RAMIL, Justice,
with whom MOON, Chief Justice, joins.
We granted certiorari to review the memorandum opinion of the Intermediate Court of Appeals (ICA) filed on May 10, 1993. The central issue before us is whether the express right to privacy located in article I, section 6 of the Hawai‘i Constitution1 encompasses a right to possess and use marijuana2 for recreational purposes. Because we believe that the right to privacy does not in-[442] elude such a right, we affirm the ICA’s decision.
I. BACKGROUND
The facts of this case are not in dispute. On October 20, 1990, at approximately 10:16 p.m., Petitioner-Appellant Lloyd Malian was arrested in the parking lot of the Waikiki Shell after Honolulu police officers, attracted by the odor of burning marijuana, found a partially burnt marijuana cigarette in Malian’s automobile. Malian was charged with promoting a detrimental drug in the third degree, in violation of Hawaii Revised Statutes (HRS) § 712-1249 (1993).3
Malian does not deny that he broke the law on the night in question:
[MALLAN:] I have a deep interest in music and I’d just seen the Honolulu Symphony concert and went back to my car and listened to the — turned on the radio and listened to a jazz tune that I hadn’t heard for years, by Keith Jarrett....
And I had a little bit of, of marihuana with me. And I thought as commemoration of my listening to Keith Jarrett, I would smoke a joint or whatever I had left, which was minimal.
And I was pursuing my sense of happiness and that it would enhance my appreciation of the music....
... I thought I was in privacy. Nobody was around. It was after the concert and I had no place to go, really. And a voice [inside my head] said, “Don’t do it,” but I did it anyway.
Before trial, however, Malian filed a motion to dismiss. In support of the motion, Malian argued, inter alia, that the right to smoke marijuana is protected by the Hawaii Constitution’s right to privacy. At a subsequent hearing on the motion, the parties stipulated to the testimony of Malian’s expert witnesses. The witnesses would have testified that, in their opinion, marijuana is not addictive and that there is no proof that the use of marijuana is harmful to the user or to others. However, the witnesses would also have testified that the effects of marijuana have been the subject of debate. The experts would have further testified that, in their opinion, the studies concluding that marijuana has harmful effects are speculative and flawed. After oral argument on the motion, the trial court rejected Malian’s contentions. The trial court ruled that “possession and use of marihuana ... is not protected under our right of privacy.” The trial court ruled that “the possession of marihuana ... does not rank as any kind of fundamental freedom” and that the statute need only be supported by a rational basis, not a compelling state interest. The trial court noted that the question whether marijuana has harmful effects is a controversial area. The trial court noted that, according to the stipulated evidence, some literature supports the conclusion that marijuana is harmful, while other literature supports the conclusion that it is harmless. Consequently, the trial court ruled that, in applying the rational basis test, the statute is constitutional.
The case then proceeded to trial, and the court found Malian guilty. Malian was sentenced to a fine of $60. Malian filed a timely notice of appeal, and the case was assigned to the ICA. The ICA based its decision on our prior case law holding that the possession of marijuana for personal use is not protected by the right to privacy. See State v. Bachman, 61 Haw. 71, 595 P.2d 287 (1979); State v. Renfro, 56 Haw. 501, 542 P.2d 366 (1975); State v. Baker, 56 Haw. 271, 535 P.2d 1394 (1975). The ICA noted that Renfro and Baker were decided before article I, section 6 was added to the Hawaii Constitution. The ICA further noted that, although Bachman was decided five months after article I, section 6 was ratified, the appellate briefs in Bachman were filed before ratification. Nevertheless, the ICA felt obligated to follow [443] Bachman and, therefore, affirmed Malian’s conviction. Malian subsequently applied to this court for a writ of certiorari, which we granted.
II. STANDARD OF REVIEW
The scope of the right to privacy under article I, section 6 of the Hawai'i Constitution is a question of constitutional law. “We answer questions of constitutional law by exercising our own independent constitutional judgment based on the facts of the case. Thus, we review questions of constitutional law under the right/wrong standard.” State v. Arceo, 84 Hawai'i 1, 11, 928 P.2d 843, 853 (1996) (internal quotation marks and citations omitted).
III. DISCUSSION
Initially, we note that although our prior eases addressing the constitutionality of our marijuana possession statutes did address the right to privacy, see Bachman, supra; Renfro, supra; Baker, supra, those cases did not directly address article I, section 6. Thus, the specific question whether article I, section 6 encompasses a constitutional right to possess and use marijuana has yet to be answered by this court.
A. Our Prior Privacy Case Law: Mueller, Kam, and Baehr
1. Two Approaches
To date, our case law interpreting article I, section 6 has apparently established two distinct approaches to the right to privacy.4 The first approach was applied by this court in State v. Mueller, 66 Haw. 616, 671 P.2d 1351 (1983), and later by the plurality in Baehr v. Lewin, 74 Haw. 530, 852 P.2d 44, reconsideration granted in part, 74 Haw. 650, 875 P.2d 225 (1993). Under this approach, “only personal rights that can be deemed ‘fundamental’ or ‘implicit in the concept of ordered liberty’ are included in this guarantee of personal privacy.” Mueller, 66 Haw. at 628, 671 P.2d at 1355 (quoting Roe v. Wade, 410 U.S. 113, 152, 93 S.Ct. 705, 726, 35 L.Ed.2d 147 (1973)) (citations omitted). In determining which rights are fundamental, we must look
to the “traditions and [collective] conscience of our people” to determine whether a principle is “so rooted [there] ... as to be ranked as fundamental.” ... The inquiry is whether a right involved “is of such a character that it cannot be denied without violating those ‘fundamental principles of liberty and justice which lie at the base of all our civil and political institutions’ .... ”
Baehr, 74 Haw. at 556, 852 P.2d at 57 (quoting Griswold v. Connecticut, 381 U.S. 479, 493, 85 S.Ct. 1678, 1686, 14 L.Ed.2d 510 (1965) (Goldberg, J., concurring)) (alterations in original). If a right is determined to be fundamental, it is “subject to interference only when a compelling state interest is demonstrated.” Comm. Whole Rep. No. 15, in 1 Proceedings of the Constitutional Convention of Hawai'i of 1978, at 1024 (1980). See also Mueller, 66 Haw. at 627, 671 P.2d at 1359. In the absence of a fundamental right, however, a statute need only satisfy the minimum rationality requirements of due process, ie., it must have a “rational basis.” Id. at 628, 671 P.2d at 1359.
In the past, we have applied the Mueller /Baehr approach in rejecting claims that certain acts are protected by the right to privacy. In Mueller, our first case directly addressing the scope of article I, section 6, we held that prostitution is not protected by the right to privacy because the decision “to engage in sex for hire at home” is not a fundamental right nor is basic to ordered liberty. Id. at 628, 630, 671 P.2d at 1359, 1360. Similarly, in Baehr, the plurality held, in an opinion written by Justice Levinson:
[444] [W]e do not believe that a right to same-sex marriage is so rooted in the traditions and collective conscience of our people that failure to recognize it would violate the fundamental principles of liberty and justice that lie at the base of all our civil and political institutions. Neither do we believe that a right to same-sex marriage is implicit in the concept of ordered liberty, 'such that neither liberty nor justice would exist if it were sacrificed. Accordingly, we hold that the [plaintiffs] do not have a fundamental constitutional right to same-sex marriage arising out of the right to privacy or otherwise.
Baehr, 74 Haw. at 556-57, 852 P.2d at 57.
It should be noted that, in applying the Mueller /Baehr approach, we have tended to focus on “personal decisions relating to marriage, procreation, contraception, family relationships, and child rearing and education.” Mueller, 66 Haw. at 627, 671 P.2d at 1359 (quoting Carey v. Population Servs. Int’l, 431 U.S. 678, 685, 97 S.Ct. 2010, 2016, 52 L.Ed.2d 675 (1977)) (internal quotation marks and ellipses omitted). A report from the 1978 Constitutional Convention’s Committee of the Whole, “reflecting the consensus of the assembly,” id. at 625, 671 P.2d at 1357, stated that the right to privacy “is similar to the privacy right discussed in [federal] cases such as Griswold v. Connecticut, 381 U.S. 479[, 85 S.Ct. 1678, 14 L.Ed.2d 510 (1965), Eisenstadt v. Baird, 405 U.S. 438, 92 S.Ct. 1029, 31 L.Ed.2d 349 (1972), Roe v. Wade, 410 U.S. 113, 93 S.Ct. 705, 35 L.Ed.2d 147] (1973), etc.” Comm. Whole Rep. No. 15, 1 Proceedings, at 1024. Griswold and Eisen-stadt both involved contraception and Roe dealt with abortion. See Griswold, swpra; Eisenstadt, supra; Roe, supra. Accepting the reasoning in Mueller, Justice Levinson wrote in Baehr: “We ultimately concluded in Mueller that the federal cases cited by the Convention’s committee of the whole should guide our construction of the intended scope of article I, section 6.” Baehr, 74 Haw. at 552, 852 P.2d at 55. Therefore, “[w]hile the outer limits of this aspect of privacy have not been markedf,]” Mueller, 66 Haw. at 627, 671 P.2d at 1359 (quoting Carey, 431 U.S. at 685, 97 S.Ct. at 2016), it is clear that the framers of article I, section 6 and our own decisions have emphasized protection of intimate personal relationships such as those concerning marriage, contraception, and the family.
The second approach, adopted by this court in State v. Kam, 69 Haw. 483, 748 P.2d 372 (1988), is ultimately based on the United States Supreme Court’s decision in Stanley v. Georgia, 394 U.S. 557, 89 S.Ct. 1243, 22 L.Ed.2d 542 (1969). In Stanley, the Court held that the right to read or view pornographic material in the privacy of one’s home is protected by the First Amendment. Id. at 565, 89 S.Ct. at 1248 (“If the First Amendment means anything, it means that a State has no business telling a man, sitting alone in the privacy of his own house, what books he may read or what films he may watch.”). In Kam, we accepted the reasoning in Stanley, but additionally based the right to read or view pornographic material within the home on article I, section 6. Kam, 69 Haw. at 493-94, 748 P.2d at 378-79. We held that the right “to read or view pornographic material in the privacy of one’s home must be afforded the protection of the Hawaii Constitution article I, section 6[.]” Id. at 493, 748 P.2d at 378-79. Furthermore, we extended the principles in Stanley to include the “correlative right to purchase [pornographic] materials for ... personal use [at home].” Id. at 495, 748 P.2d at 380 (emphasis added). We reasoned that “[i]t is obvious that an adult person cannot read or view pornographic material in the privacy of his or her own home if the government prosecutes the sellers of pornography ... and bans any commercial distribution.” Id. at 495, 748 P.2d at 379. Thus, under the Stanley/Kam approach, the right to privacy located in article I, section 6 encompasses the right to read or view pornographic material in the privacy of one’s home, as well as the correlative right to purchase such materials for use in one’s home. The State cannot interfere with these rights unless a compelling state interest is demonstrated. Id.
It should be noted that there are two significant aspects of the Stanley /Kam approach. First, the approach focuses squarely on the home as the situs of privacy. Rather than focusing on intimate relationships, as in the Mueller /Baehr approach, the Stanley [445] /Kam approach is tied to a specific place. Stanley repeatedly referred to the privacy of one’s own home:
Moreover, in the context of this case — a prosecution for mere possession of printed or filmed matter in the privacy of one’s home — that right takes on an added dimension_ He is asserting the right to read or observe what he pleases — the right to satisfy his intellectual and emotional needs in the privacy of his own home. ... Whatever may be the justifications for other statutes regulating obscenity, we do not think they reach into the privacy of one’s own home. ... As we have said, the States retain broad power to regulate obscenity; that power simply does not extend to mere possession by the individual in the privacy of his own home.
Stanley, 394 U.S. at 564, 565, 568, 89 S.Ct. at 1247, 1248, 1249 (emphases added). “The Constitution extends special safeguards to the privacy of the home, just as it protects other special privacy rights such as those of marriage, procreation, motherhood, child rearing, and education.” United States v. Orito, 413 U.S. 139, 142, 93 S.Ct. 2674, 2677, 37 L.Ed.2d 513 (1973). “The protection afforded by Stanley v. Georgia, 394 U.S. 557, 89 S.Ct. 1243, 22 L.Ed.2d 542 (1969), is restricted to a place, the home. In contrast, the constitutionally protected privacy of family, marriage, motherhood, procreation, and child rearing is not just concerned with a particular place, but with a protected intimate relationship.” Paris Adult Theatre I v. Slaton, 413 U.S. 49, 66 n. 13, 93 S.Ct. 2628, 2640 n. 13, 37 L.Ed.2d 446 (1973). It is true that Kam extended the principles in Stanley to include the buying and selling of pornographic materials, and such commercial activities do not take place in the home. However, we also stated in Kam that the right to purchase pornographic materials is a “eorrel-ative right” to the right established by Stanley. Thus, even though the material may be purchased outside the home, it still must be purchased for personal use within the home. Therefore, a crucial factor in the Stanley /Kam approach is its emphasis on the home.
The second aspect of the Stanley /Kam approach is that freedom of speech and freedom of the press are strongly implicated. Pornography and obscenity deal with printed or filmed matter and, consequently, raise First Amendment concerns. Stanley was based on the First Amendment, as applied to the states through the Fourteenth Amendment. Stanley, 394 U.S. at 568, 89 S.Ct. at 1249 (“We hold that the First and Fourteenth Amendments prohibit making mere private possession of obscene material a crime.” (Emphasis added.)). Although Kam subsequently grounded the right to read or view pornographic material within the home on article I, section 6, we cannot ignore the fact that freedom of speech and freedom of the press are essential factors in the Stanley /Kam analysis.
2. The Present Case
In the present case, Malian argues that the right to privacy in article I, section 6 encompasses the right to possess marijuana for personal use. We disagree. Applying the Mueller/Baehr approach, it is clear that the right to possess and use marijuana cannot be considered a “fundamental” right that is “implicit in the concept of ordered liberty.” We cannot say that smoking marijuana is a part of the “traditions and collective conscience of our people.” In Hawai'i, possession of marijuana has been illegal since 1931. See 1931 Haw. Sess. L. Act 152, § 12, at 155-56. In the rest of the United States, the possession and/or use of marijuana, even in small quantities, is almost universally prohibited.5 Therefore, tradition appears to be in [446] favor of the prohibition against possession and use of marijuana. Additionally, we have no reason to believe that the collective conscience of the people supports the possession and use of marijuana under the circumstances of this case. Furthermore, we cannot say that the principles of liberty and justice underlying our civil and political institutions are violated by marijuana possession laws. We dare say that liberty and justice can exist in spite of the prohibition against marijuana possession. Therefore, the purported right to possess and Use marijuana is not a fundamental right and a compelling state interest is not required.
Because the right to privacy is not implicated, HRS § 712-1249 need only survive the rational basis test.
Generally, where no fundamental rights or suspect classifications are involved, there is a due process violation only if there is no rational basis to sustain the challenged statute.... Under the rational basis test, we inquire as to whether a statute rationally furthers a legitimate state interest. Our inquiry seeks only to determine whether any reasonable justification can be found for the legislative enactment.
Estate of Coates v. Pacific Engineering, 71 Haw. 358, 363-64, 791 P.2d 1257, 1260 (1990) (citations omitted). Furthermore, we have long held that: “(1) legislative enactments are presumptively constitutional; (2) a party challenging a statutory scheme has the burden of showing unconstitutionality beyond a reasonable doubt; and (3) the constitutional defect must be clear, manifest, and unmistakable.” State Organization of Police Officers (SHOPO) v. Society of Professional Journalists—University of Hawai'i Chapter, 83 Hawai'i 378, 389, 927 P.2d 386, 397 (1996) (citing Pray v. Judicial Selection Comm’n, 75 Haw. 333, 340, 861 P.2d 723, 727 (1993)). See also Kam, 69 Haw. at 496, 748 P.2d at 380; Mueller, 66 Haw. at 626-27, 671 P.2d at 1358. Thus, in the present case, Malian has the heavy burden of demonstrating that HRS § 712-1249 lacks any rational basis. If Malian fails to satisfy his burden, the statute is presumed to be constitutional and must be upheld.
We believe that Malian has failed to satisfy his burden. The stipulated evidence provided by Malian’s expert witnesses certainly support his argument that marijuana is not harmful. However, those experts [447] would also have testified that the question whether marijuana has harmful effects is still controversial and that there are studies supporting the other side of the debate. “It is well settled that when a substance has been proscribed as harmful, the presumption of constitutionality applies although there are conflicting scientific views as to its harmful effects.” State v. Baker, 56 Haw. 271, 276, 535 P.2d 1394, 1397 (1975). Thus, insofar as a genuine controversy exists and scientists have not reached a consensus as to the harmful effects of marijuana, we cannot say that Malian has sufficiently rebutted the presumption of constitutionality attached to HRS § 712-1249 and that the statute lacks any rational basis. See id. at 278, 535 P.2d at 1398; State v. Renfro, 56 Haw. 501, 503, 542 P.2d 366, 368 (1975) (holding that a marijuana possession statute’s presumption of constitutionality had not been sufficiently rebutted).6 It is not our role to make an independent legislative determination as to the harmfulness of marijuana. Our role is to determine whether Malian has overcome the presumption of constitutionality and has proven that the statute is not supported by any rational basis at all. This we cannot say.
It is also clear that the Stanley /Kam approach does not support Malian’s purported right to possess and use marijuana. The record indicates that Malian was not in the privacy of his own home when he was arrested for possession of marijuana. Rather, he was sitting in an automobile parked in a public parking lot. Additionally, this case involves the possession of marijuana, not the possession of pornographic material. Therefore, neither of the two elements required under the Stanley /Kam approach have been met, and the right to privacy does not apply on this basis.
However, we note that because Malian relies on Kam in arguing this case, he is apparently suggesting that we extend the Stanley /Kam approach beyond the home and beyond pornography. We decline to do so. Stanley itself limited its application to cases implieat-tag First Amendment concerns. The Court noted:
What we have said in no way infringes upon the power of the State or Federal Government to make possession of other items, such as narcotics, firearms, or stolen goods, a crime. Our holding in the present case turns upon the Georgia statute’s infringement of fundamental liberties protected by the First and Fourteenth Amendments. No First Amendment rights are involved in most statutes making mere possession criminal.
Stanley, 394 U.S. at 568 n. 11, 89 S.Ct. at 1249 n. 11. Thus, by its own terms, Stanley rejected any application to drug possession cases. Furthermore, by attempting to sever Stanley and Kam from the concept of privacy within the home, Malian appears to suggest that the right to privacy should protect a defendant any time he subjectively feels that he is “in privacy.” In the present case, Malian thought that he was “in privacy” when he was sitting in an automobile in a public parking lot. We are not prepared to extend the right to privacy this far. To do so would give “talismanic effect” to the phrase “in privacy” — an approach we have rejected in the past. See Baehr, 74 Haw. at 555, 852 P.2d at 57; Mueller, 66 Haw. at 630, 671 P.2d at 1360.
B. Further Approaches to the Right to Privacy
Although, to date, our cases have recognized two approaches to the right to privacy, this does not mean that additional approaches cannot be adopted in the future. In Mueller, we were careful to note that “the outer limits of this aspect of privacy [ie., the personal autonomy prong] have not been marked[.]” Mueller, 66 Haw. at 627, 671 P.2d at 1359.
The approach taken in Mueller and Baehr was based on federal cases such as Griswold, Eisenstadt, and Roe. Similarly, the approach taken in Kam was based on Stanley, another federal case. Nevertheless, we are not limited to the federal interpretation [448] of constitutional rights and have often extended the protections of the Hawaii Constitution beyond those of the United States Constitution. See, e.g., State v. Bowe, 77 Hawai'i 51, 57, 881 P.2d 538, 544 (1994); State v. Lessary, 75 Haw. 446, 453-57, 865 P.2d 150, 154-55 (1994); State v. Quino, 74 Haw. 161, 170, 840 P.2d 358, 362, reconsideration denied, 74 Haw. 650, 843 P.2d 144 (1992), cert. denied, 507 U.S. 1031, 113 S.Ct. 1849, 123 L.Ed.2d 472 (1993); State v. Kaluna, 55 Haw. 361, 369, 520 P.2d 51, 58-59 (1974); State v. Texeira, 50 Haw. 138, 142 n. 2, 433 P.2d 593, 597 n. 2 (1967). “As the ultimate judicial tribunal with final, unre-viewable authority to interpret and enforce the Hawaii Constitution, we are free to give broader privacy protection than that given by the federal constitution.” Kam, 69 Haw. at 491, 748 P.2d at 377. Moreover, unlike the federal constitution, our state constitution contains a specific provision expressly establishing the right to privacy as a constitutional right. Thus, our case law and the text of our constitution appear to invite this court to look beyond the federal standards in interpreting the right to privacy.
Consequently, applying the Mueller /Baehr approach and the Stanley /Kam approach to the facts of this case is simply an initial step in the analysis. The question remains whether we should adopt another, completely new approach not based on federal ease law. The development of new approaches to the right to privacy will, of course, take place on a case-by-case basis, as different factual situations arise and new legal standards are formulated.7 However, regardless of the direction in which our privacy jurisprudence evolves, it is clear, at present, that our right to privacy does not extend to the possession and use of marijuana.
“[W]e have long recognized that the Hawaii Constitution must be construed with due .regard to the intent of the framers and the people adopting it, and that the fundamental principle in interpreting a constitutional provision is to give effect to that intent.” Convention Center Authority v. Anzai, 78 Hawai'i 157, 167, 890 P.2d 1197, 1207 (1995) (internal quotation marks and citations omitted). Based on the committee reports and debates in the Constitutional Convention, we believe that the delegates adopting the privacy provision did not intend to decriminalize the possession and use of contraband drugs.
Nothing in the committee reports indicates that the delegates intended such a drastic step as the decriminalization of drugs for personal consumption. If the delegates had intended such a result, surely they would have placed an explicit reference in the committee reports. Instead, the committee reports contain no mention of the legalization of illicit drugs. See Stand. Comm. Rep. No. 69, in 1 Proceedings, at 674-76; Comm. Whole Rep. No. 15, in 1 Proceedings, at 1023-24.
A close reading of the convention debates reveals a sincere concern, perhaps even a strong fear, among the delegates that an express right to privacy might further impede the battle against illegal drugs.
Now, what alarms me is that by putting in the language as it is right now — that the right to privacy “is recognized and shall not be infringed without the showing of a compelling state interest” — goes beyond our present statutory law and would in fact hinder law enforcement.... The result would then be that it would be virtually impossible, as I can see it, to stop criminal activity conducted in what can be considered a dwelling. For instance, if a [449] person were to manufacture cocaine, angel dust or what have you, if it’s for the purpose of manufacturing for personal use, ... I don’t see how anyone can say that there’s a compelling state interest to go in there. This language seems to say that it’s all right for a person to do anything he wants as long as we cannot show that someone else will be affected.
2 Proceedings, at 629-30 (Delegate Tam). In response, Delegate Hino reassured Delegate Tam that the privacy provision was not intended to hinder law enforcement or protect criminals.
I’d like to allay the fears of law enforcement officials and people connected with law enforcement that this provision will make it a little more difficult for the law to be enforced. This factor was recognized during our committee’s deliberations.... [W]e proposed that this privacy provision be put in a separate section, of and by itself, to show that it was not the intent of the committee to upset any kind of precedents on criminal justice or law enforcement procedures; that this privacy provision would refer to and protect the rights of noncriminals.
Id. at 630 (Delegate Hino) (emphasis added). Other delegates raised similar concerns:
I feel that the greatest benefit in the long run in Hawaii shall be from the criminal element_ I honestly feel from my experience that this right to privacy is a protective device for these so-called professional criminals, who have become so sophisticated in their techniques and their planning.... And this type of right to privacy, as good as it is for all of us, somehow will have an insidious effect on a very serious concern in Hawaii today — the rising tide of crime.
Id. at 632 (Delegate Chung).
[I]f, as the previous delegate has said, smoking marijuana was one of the main reasons this has been proposed,
