Berdon, J.
The defendant is charged with possession of “a cannabis-type substance,1 to wit: [325]*325marihuana, with intent to sell2 or dispense, in violation of” General Statutes § 19-480 (b).3 Before the [326]*326court is the defendant’s motion to quash,4 in which inter alia5 he claims that the statute is unconstitutional as it pertains to possession with intent to sell or dispense marihuana because it arbitrarily and irrationally classifies marihuana with far more dangerous drugs. It is his claim that such classification is in violation of the equal protection clauses of the fourteenth amendment to the federal constitution and article first, § 20, of the Connecticut constitution.6
The defendant, charged with violation of § 19-480 (b), in part bases his constitutional claims on the assumption that violations concerning narcotic substances (morphine- and cocaine-type drugs)7 fall within this paragraph for penalty purposes. Although the wording of this statute leaves much to be desired, there can be no question that the legislature intended to classify narcotic substances under paragraph (a), which calls for a much more severe penalty.8 Paragraph (a) prohibits acts pertaining to narcotic substances and hallucinogenic substances other than marihuana, and para[327]*327graph (b) applies to all other controlled substances, including marihuana, barbiturate-type drugs9 and amphetamine-type substances.10 The court must therefore determine whether this classification of marihuana, amphetamines and barbiturates for penalty purposes is a violation of the equal protection clauses of the federal and state constitutions.
“Equal protection analysis must commence with a determination of whether a legislative classification . . . impinges upon a fundamental right. Where the legislation impinges upon a fundamental right ... it must be struck down unless justified by a compelling state interest. Dunn v. Blumstein, 405 U.S. 330, 335, 342 .... Where the statute does not involve fundamental rights . . . the legislation will withstand constitutional attack if the distinction is founded on a rational basis. McGinnis v. Royster, 410 U.S. 263, 270 . . . ; Dandridge v. Williams, 397 U.S. 471, 484, 485 ... ; F. S. Royster Guano Co. v. Virginia, 253 U.S. 412, 415 . . . ; In re Application of Griffiths, 162 Conn. 249, 258 ..., rev’d, 413 U.S. 717 ... ; see Douglas v. California, 372 U.S. 353, 358 .. . .” Laden v. Warden, 169 Conn. 540, 542; Liistro v. Robinson, 170 Conn. 116, 124. Possession of marihuana is not a fundamental right guaranteed by the constitution. [328]*328Therefore, in determining whether the classification is constitutional, the court will apply the “rational relationship” test.11
That test requires that the statutory classification “be based upon some real and substantial distinction, bearing a reasonable and just relation to the things in respect to which such classification is imposed; and classification cannot be arbitrarily made without any substantial basis.” Southern Ry. Co. v. Greene, 216 U.S. 400, 417; Atchison, T. & S.F. Ry. Co. v. Vosburg, 238 U.S. 56, 59 . . . ; State v. Hurliman, 143 Conn. 502, 506. (But see footnote 59 infra). And it is clear that if the statute includes within the class an object whose inclusion is irrational or arbitrary, such inclusion is in violation of the equal protection clause. “[W]e recognize that the constitutionality of a statute, valid on its face, may be assailed by proof of facts tending to show that the statute as applied to a particular article is without support in reason because the article, although within the prohibited class, is so different from others of the class as to be without the reason for the prohibition.” United States v. Carolene Products Co., 304 U.S. 144, 153. But, in “adjusting legislation to the need of the people of a State, the legislature has a wide discretion and it may be fully conceded that perfect uniformity of treatment ... is neither practical nor desirable, that classification ... is constantly necessary and that questions of proper classification are not free from difficulty.” Truax v. Corrigan, 257 U.S. 312, 337. “Primarily the question of classification is one for the legislature, and the courts will not interfere unless it is clearly unreasonable.” State v. Zazzaro, 128 Conn. 160, 166.
[329]*329It then remains to be seen whether the statute in question meets this rational relationship test. It must be borne in mind that when challenging the constitutionality of a statute the defendant has a heavy burden of proof.12 Kellems v. Brown, 163 Conn. 478, 486. “Because of the separation of powers, one claiming that a legislative enactment is invalid on the ground that it is unconstitutional must establish its invalidity on that ground beyond a reasonable doubt.” Adams v. Rubinow, 157 Conn. 150, 152; Kellems v. Brown, supra. “It is our duty to approach the question with great caution, examine it with infinite care, make every presumption and intendment in its favor, and sustain the Act unless its invalidity is, in our judgment, beyond reasonable doubt.” Beach v. Bradstreet, 85 Conn. 344, 349. Within this context, we must review the statutory classification of marihuana.
It is obvious that the purpose of the legislation is not only to protect the health of those who may be tempted to use marihuana but, in the exercise of the state’s police power, to protect society from the effects of a drug which the legislature concluded to be appropriately classified for penalty purposes with amphetamines and barbiturates. This court is therefore required to look at the effect of marihuana on both the user’s13 health and the public welfare, and to compare this to the effect of amphetamines and barbiturates.
The court is not required to restrict itself to the facts or data that were present before the legisla[330]*330ture when the legislation prohibiting the conduct was adopted. “[A] police regulation, although valid when made, may become, by reason of later events, arbitrary and confiscatory in operation.” Abie State Bank v. Bryan, 282 U.S. 765, 772; Leary v. United States, 395 U.S. 6, 38. “[A] Court is not at liberty to shut its eyes to an obvious mistake, when the validity of the law depends upon the truth of what is declared. ... A law depending upon the existence of . . . certain facts to uphold it may cease to operate if . . . the facts change even though valid when passed.” Chastleton Corporation v. Sinclair, 264 U.S. 543, 547. So, even if there were no empirical data available to the legislature at the time, or the legislature had erroneous information regarding the effects of marihuana, this court is not bound to review the constitutionality of the statute based on these misconceptions. The question before this court is whether the present state of knowledge of the effects of marihuana provides a rational basis within the standards previously set forth to classify it with amphetamines and barbiturates for penalty purposes.14
The defendant, pursuant to a stipulation entered into with the state, introduced in evidence transcripts of the testimony of expert witnesses for the defendant in the case of United States v. Maiden, 355 F. Sup. 743 (D. Conn.). The state offered no evidence. This testimony was given by Lester Grin-spoon, professor of psychiatry at Harvard Medical School, Joel Fort of the University of California and a former consultant to the United Nations World Health Organization, and Edward Breeher, a scientific research writer. The court is satisfied [331]*331that the evidence constituted a sufficient record on which it could determine the issues raised in this case.
The facts relied on by the court in its decision are based on the testimony contained in the transcripts. The court has also made references to corroborating empirical data and other studies which include the first report of the National Commission on Marihuana and Drug Abuse, entitled “Marihuana: A Signal of Misunderstanding” (1972), cited as “Signal of Misunderstanding,” and its second report, entitled “Drug Use in America: Problems in Perspective” (1973), cited as “Drug Use in America.” This commission was authorized by Congress in the Comprehensive Drug Abuse Prevention and Control Act of 1970, and it was directed to study and report on marihuana.15 The significant findings of the commission were confirmed by the Canadian Commission of Inquiry into the Non-Medical Use of Drugs, Cannabis (1972).
Marihuana comes from the hemp plant, cannabis sativa. It is a psychoactive drug16 and its strength [332]*332varies greatly depending on the amount of isomers of tetrahydroeannabiniol, or THC, from the plant’s resin, it contains. Marihuana, which is generally used in this country, has the least potency; the strongest is hashish.17 Although hashish is many times stronger in effect than marihuana, Connecticut statutes make no distinction between these drugs.18
The evidence introduced before this court is that there are no significant short-term physiological effects from the use of marihuana.19 It has been described by Grinspoon as “a remarkable drug for the paucity of physiological effects.” The minimal short-term physical effects are limited to the reddening of the whites of the eyes, a slight lowering of blood pressure and an increase in the pulse rate.20 [333]*333The short-term psychological effects21 are characterized by a euphoria of good feeling,22 increase of the sense of perception, enhanced appetite and some effect on the short-term memory during the course of the euphoric feeling.23 For a small number of users, it may cause unpleasant feelings of anxiety and accentuate preexisting neuroses. There are no known long-term or permanent physiological or psychological effects from the use of marihuana.24
[334]*334Marihuana is not addicting,25 but for heavy, long-term users it can produce a mild psychological dependence26 in the manner that a person could obtain a habit through ordinary use and routine.27
Marihuana does not have a high potential for abuse.28 It does not lead to crime or violent [335]*335behavior.29 “Marihuana use, in and of itself, is neither causative of, nor directly associated with crime, either violent or non-violent. In fact, marihuana tends to be underrepresented among assaultive offenders, especially when compared with users of alcohol, amphetamines and barbiturates.” Drug Use in America, p. 165. The drug is not aphrodisiac30 and does not cause death.31
One misconception must be put to rest and that is the “stepping stone argument.”32 “[T]he ‘stepping stone argument’ that marijuana use leads to use of ‘hard narcotics’ has no scientific basis. The President’s Commission on Law Enforcement and Administration of Justice, Task Force Report: Narcotics and Drug Abuse, found at pp. 13-14: ‘The charge that marihuana “leads” to the use of addicting drugs needs to be critically examined. There is evidence that a majority of the heroin users who come to the attention of public authorities have, in fact, had some prior experience with marihuana. But this does not mean that one leads to the other in the sense that marihuana has an intrinsic quality that creates a heroin liability. There are too many marihuana users who do not graduate to heroin, and too many heroin addicts with no known prior marihuana [336]*336use, to support such a theory. Moreover there is no scientific basis for such a theory. The basic text on pharmacology, Goodman and Gilman, The Pharmacological Basis of Therapeutics (Macmillan 1960) states quite explicitly that marihuana habituation does not lead to the use of heroin.’ (Emphasis added.)” People v. Sinclair, 387 Mich. 91, 111.
There is evidence that marihuana can cause psychological disturbances in users who have a predisposition to these disorders, but such disturbances might equally be precipitated in these persons by alcohol, other psychoactive drugs or a traumatic event.33 And there is evidence that marihuana use has an effect on driving performance.34 It should, however, be noted that there is other legislation to protect society by imposing criminal penalties for operating a motor vehicle under the influence of intoxicating liquor or drugs.35
[337]*337In sum, the overwhelming evidence presented to this court indicates that experimental, intermittent and moderate use of marihuana “carries minimal risk to the public health” and that “neither the marihuana user nor the drug itself can be said to constitute a danger to public safety.”36 These physiological, psychological, socioeconomic and societal effects of marihuana must be compared to those of the other members of the classification, to wit: barbiturates and amphetamines.
The short-term psychological effects of a barbiturate37 are that it acts as a depressant on the brain comparable to narcotics and alcohol, which produces sleep, coma and stupor.38 There is an impairment of the health of the individual as a result of loss of appetite, malnutrition and lack of attention to personal hygiene. The long-term effects are that a user has the feeling that life centers around him, there is an' impairment of social and vocational functioning and a tendency to become a drug abuser. The user develops a tolerance for the drug and physical dependence on it; he then begins to use it daily as a pattern of his life. When taken off the drug, the user experiences withdrawal illness.39 This withdrawal illness is characterized by convulsions and toxic psychosis.
Barbiturates can increase aggression40 and lead to crime, particularly in the case of those who are predisposed to violence, in much the same way as [338]*338alcohol.41 Overdose of the drug can cause death;42 death may also be caused by untreated convulsions experienced by the user in withdrawal.
When asked whether it was reasonable to classify marihuana with barbiturates in terms of the effect on users and the potential for abuse, Fort testified: “It’s not reasonable at all. They are unlike each other pharmacologically, they differ markedly in their short-term effect, differ markedly in their long-term effect. When you compare heavy use of the two drugs, marihuana has a very, very low potential for abuse and barbiturates have a high potential for abuse. Marihuana does not produce death, even in the enormous doses, and barbiturates frequently produce death or commonly produce it with large doses.”43
Authorities also agree that amphetamines44 are truly dangerous drugs which have become a major problem in the United States.45 The short-term physiological effects of the drug are increase in pulse rate, increase in alertness, restlessness, agitation, nervousness, tremors, increase in blood pressure and increase in perspiration. The short-term psychological effects are euphoric feeling, a sense of confidence, insomnia and diminution of appetite.
The most prevalent difference between amphetamines and marihuana is to be found in the long-term psychological effects, which for amphetamines are characterized by a severe psychological dependence [339]*339and addiction.46 Amphetamine use can cause psychosis which is indistinguishable from paranoid schizophrenic reaction. The drug can cause serious hallucinations and delusions, particularly paranoid delusions. The use of amphetamines can cause death. Amphetamines have a high potential for abuse and frequently lead to crime and violence.47 One particular amphetamine, methamphetamine (commonly referred to by the street name “speed”) should be singled out. The violence, paranoia and [340]*340physical depletion which result from this drug are substantially more severe than result from other forms of amphetamines.48
Fort also testified that marihuana and amphetamines “are totally dissimilar pharmacologically, socioeconomically in their street-pattern use and their potential for abuse and in their effect both from short-term and long-term use, so there is no rationale for . . . [classifying] them together with marihuana.”
The defendant also claims that the exclusion of other psychoaetive drugs, which are far more dangerous than marihuana, from the prohibitive classification is arbitrary and irrational and therefore violates the equal protection clause. The defendant points out that the psychoaetive drugs alcohol and nicotine49 are more dangerous than marihuana to the public health and welfare and that the possession and sale of these drugs are not outlawed by § 19-480 of the General Statutes; these drugs are specifically excluded as controlled substances under § 19-443 (8) and are not subject to the criminal penalties imposed under chapter 359 of the General Statutes, entitled “Dependency-Producing Drugs.” But these drugs are controlled or regulated by legislation, and violation of such legislative controls results in misdemeanor penalties.50
Federal decisions under the fourteenth amendment do not hold that the legislature is required to [341]*341regulate or prohibit all harmful substances just because it regulates some of those substances. “It is no requirement of equal protection that all evils of the same genus be eradicated or none at all.” Railway Express Agency, Inc. v. New York, 336 U.S. 106, 110; see Dandridge v. Williams, 397 U.S. 471, 486; United States v. Kiffer, 477 F.2d 349, 355 (2d Cir.), cert. denied, 414 U.S. 831. “Assuming some degree of control of marijuana use is permissible, it does not follow that the political obstacles to placing controls on alcohol and tobacco should render the legislature unable to regulate other substances equally or less harmful. It is not irrational for the legislature to regulate those public health areas where it can do so, when there exists other areas where controls are less feasible.” Ravin v. Alaska, 537 P.2d 494, 512 (Alas.).
But the obiter dicta of the Connecticut Supreme Court indicates that irrational exemptions from a statute would be a denial of the guarantees under the due process clause. Our Supreme Court has consistently enunciated this rule as follows: “Legislation, even though it is within the police power, may be violative of due process if it is discriminatory in that it deals differently with different classes of persons without the existence of some natural and substantial difference, germane to the subject and purposes of the legislation, between those within the class included and those whom it leaves untouched.” Schwartz v. Kelly, 140 Conn. 176, 181; State v. Hurliman, 143 Conn. 502, 505-506; Lyman v. Adorno, 133 Conn. 511, 521; State v. Cullum, 110 Conn. 291, 295.
Whether or not such an exemption is the basis for a constitutional attack, it is still the duty of the court in this case to review the effects on the public health and welfare of the psychoactive drugs which are excluded from the classification and com[342]*342pare them to marihuana. The purpose of this examination is to aid the court in determining whether there is a rational basis for the inclusion of marihuana and whether such inclusion has relevancy to the subject and purposes of the legislation.
Heavy use of alcohol is clearly more dangerous than marihuana for the user and society.51 Alcohol is a depressant similar to barbiturates and narcotics. It causes an increase in chemical activity of the brain and loss of alertness, judgment and coordination. With larger doses, it causes drowsiness, sleep, stupor and coma. Long-term excessive use causes cirrhosis of the liver and brain damage. Cirrhosis of the liver is the actual destruction of the cells of the liver, causing sears which result in the inability of the liver to perform its metabolic functions. The brain damage is the direct destruction of brain cells which results in atrophy of the brain, that is, the shrinking of the brain with consequent impairment of memory, judgment, reasoning and ability to function in general.
Alcohol leads to habituation and can be addicting.52 Its use can lead to violence and crime.53 “There is no doubt that alcohol is involved in a large percentage of crimes of violence in the United States, especially homicide. This involvement is certainly consistent with alcohol’s known effect of releasing emotion and lessening cortical control over anger.” Kaplan, Marijuana — The New Prohibition, p. 304 (1971). It is generally accepted that alcohol is a major contributing factor in traffic accidents and fatalities; alcohol can cause chronic and acute psychoses from heavy use, can cause death, and is [343]*343a major factor in suicides.54 The psychoactive drug, alcohol, has a devastating effect on public health and safety. “Comparison of the effects of marijuana use on both the individual and society with the effects of other drug use demonstrates not only that there is no rational basis for classifying marijuana with the ‘hard narcotics,’ but, also, that there is not even a rational basis for treating marijuana as a more dangerous drug than alcohol.” People v. Sinclair, 387 Mich. 91, 104.
Nicotine also has widespread use; about sixty to seventy million people in this country regularly use the psyehoactive drug nicotine. Long-term use of nicotine may result in lung cancer, high blood pressure and stroke, bronchitis and emphysema, and coronary heart disease.55 Nicotine abuse results in approximately four hundred thousand deaths each year in the United States. None of these diseases is caused by the use of marihuana. Nicotine also leads to a strong habituation which is common among smokers.
This court has been unable to find any case wherein the constitutional issue of the rationality and reasonableness of classifying marihuana with drugs such as barbiturates and amphetamines has been decided. The issue of classifying marihuana with narcotics has been before the courts on several occasions. In those instances some courts have held that such a classification violates the equal protection clause and other courts, for a variety of reasons, have failed to declare the legislation unconstitutional.56 It would be of help to review some of these cases.
[344]*344People v. McCabe, 49 Ill. 2d 338, held unconstitutional the classification of marihuana with narcotics for penalty purposes as being in violation of the equal protection clause. The court in dicta opted for classification of marihuana with amphetamines and barbiturates for penalty purposes. This rationale was obviously based on the court’s being confronted with the classification of marihuana as a narcotic substance which called for a minimum penalty of ten years, while the classification of amphetamines and barbiturates under a different Illinois act provided for a penalty of not greater than one year. It is further apparent that the ease was argued by the defendant on this theory. Nevertheless, the court in its opinion discussed the very serious and harmful effects of amphetamines and barbiturates and compared them to marihuana, which it concluded to be a relatively harmless drug. This analysis by the court clearly demonstrates the significant differences between marihuana and the psychoactive drugs — amphetamines and barbiturates.
In People v. Sinclair, 387 Mich. 91, the court, voiding the conviction of the defendant for illegal possession of marihuana, was divided on its reasons, but two of the justices were of the opinion that the statutory classification of marihuana with narcotics was unconstitutional in that it denied equal protection of the law.
The federal District Court in United States v. Maiden, 355 F. Sup. 743 (D. Conn.), found the classification of marihuana with narcotics to be constitutional because federal legislation did separate the drugs for penalty purposes. The court also pointed out that Congress established a scheme of penalties that only applied to marihuana. Id., 748. This is not the case under the Connecticut statutes. Possession with the intent to sell or dispense marihuana, whether in small amounts or not and whether [345]*345for remnneration or not, is classified in § 19-480 (b) with such drugs as amphetamines and barbiturates. The court in Maiden did concede that if marihuana was classified with hard drugs for penalty purposes the argument of the defendant might have had force. In United States v. Kiffer, 477 F.2d 349 (2d Cir.), cert. denied, 414 U.S. 831, the court also upheld the constitutionality of a federal statute prohibiting possession with intent to distribute marihuana, on the same ground as in Maiden, i.e., Congress provides a different set of penalties for marihuana. The court further noted (p. 353) that Kiffer was convicted of possession of two tons of marihuana and alluded to the “commercial distribution of marihuana.” Apparently the trial court also had evidence before it which put in question the “present state of knowledge of the effects of marihuana.” Id., 353. This is not the case before this court; the empirical data presented to this court are sufficiently certain and complete to support its conclusions.
The only conclusion to which this court can come is that there are substantial differences between marihuana and psyehoactive drugs such as amphetamines and barbiturates. Marihuana is a relatively mild drug which causes minimal risk to the public health and does not constitute a danger to public safety.57 Amphetamines and barbiturates are drugs [346]*346which seriously affect the health of the user and have a substantial adverse effect upon the social and economic well-being of society and public safety. The irrationality of this classification is put in sharper focus by considering that other psychoactive drugs such as alcohol and nicotine, which are probably more destructive in their effects on society than marihuana, are not included.58 Although the legislature may not have been required to include these other drugs in the prohibitive classification under § 19-480 (b), the exclusion certainly demonstrates that there was no intention to outlaw all psychoactive drugs. Therefore, it is obvious that the legislature intended to include in this classification under § 19-480 (b) only those psychoactive drugs which have a serious harmful effect upon the public health and welfare. Marihuana does not have this effect.
It becomes clearly apparent that the classification of marihuana under § 19-480 (b) for penalty purposes does not rest on grounds which have a fair and substantial relation to the purposes of this legislation, nor is there any state of facts which can reasonably be conceived by this court to justify such a classification.59 This court must conclude that the classification of marihuana with the dangerous psychoactive drugs — amphetamines and barbiturates — under § 19-480 (b) is irrational and unreasonable, and therefore in violation of the equal protection clauses of the state and federal constitutions.
[347]*347The court feels compelled to comment on the practical effects of the present classification of marihuana with dangerous drugs for penalty purposes. Marihuana is widely used. The National Commission on Marihuana and Drug Abuse in 1972 estimated that twenty-four million Americans have at least tried the drug once.60 Although the incidence of use is greatest among young people, use of marihuana is found in all age groups and “in all socioeconomic groups and occupations, though slightly more predominant among persons with above-average incomes.”61 Occasional and regular use of marihuana “is almost equally prevalent among sales workers, clerical workers, skilled, semiskilled and unskilled workers, managers, owners, professionals and technical workers.”62
With such widespread use, the dangers of an irrational classification undermine a fundamental respect for the law. Those who have used the drug have not experienced the great harm supposedly attributed to it. The law in such instances loses its credibility. It severely punishes a person for conduct he regards as harmless.63 It makes it difficult to convince young people that harmful drugs such as amphetamines and barbiturates are really dangerous to health and society when they are classified with marihuana.64 It encourages young people freely to use alcohol and other psychoaetive drugs which are not prohibited by the classification.65
The practical aspects of the problem do not stop there. The number of persons arrested for violation of the marihuana laws have steadily increased. It was reported that during the year of 1973, 420,000 [348]*348were arrested in the United States, an increase of one-third from 1972.66 The National Commission on Marihuana and Drug Abuse reports that 81 percent of these individuals have no prior record of convictions of any crime and 91 percent have never been convicted of a drug-related crime.67 The social costs of enforcing these laws is staggering on these individuals and our society, and overwhelming on our law enforcement agencies.68
It should be emphasized that marihuana is a psychoactive drug, and like all psychoactive drugs, including alcohol and nicotine, it is potentially harmful depending on the intensity, frequency and duration of use. “The state has a legitimate concern with avoiding the spread of marijuana use to adolescents who may not be equipped with the maturity to handle the experience prudently . . . .” Ravin v. Alaska, 537 P.2d 494, 511 (Alas.). Therefore, under the police power of the state, the legislature may exercise its jurisdiction by prohibiting or at least controlling the distribution of marihuana.69 But in doing so, it may not arbitrarily and irrationally classify marihuana for penalty purposes with drugs which are far more dangerous.
The motion to quash is granted.
