Bronson, J.
On September 3, 1969, a criminal warrant was issued charging defendant, Dirk Bruinsma, with violation of MCLA § 335.152 (Stat Ann 1957 Rev § 18.1122) in that defendant on March 26, 1969, did unlawfully and feloniously sell, dispense, or otherwise dispose of, to John S. Rosochaki, a narcotic drug, to wit: a quantity of marijuana. The defendant was 21 years old at the time of the alleged crime.
Prom the record, it appears that defendant retained the services of Mr. Alan Kahn, an attorney from Chicago, Illinois. Although Mr. Kahn did not appear at the arraignment held on September 19, 1969, the prosecutor informed the court that Mr. Kahn had advised the defendant to stand mute. The court, after ascertaining defendant’s desire to stand mute, entered a plea of not guilty.
On September 15, 1969, a preliminary examination was held. With Mr. Kahn present, the assistant prosecutor, Mr. Kloote, made the following motion to the court:
“Judge White: It is my understanding, Mr. Kloot, that it is agreeable that Mr. Kahn be per[171]*171mitted to represent Mr. Bruinsma for these purposes here today.
“Mr.Kloot: It is, your Honor.
“Judge White: And are you moving the court for his admission here to practice before this court for these purposes today?
“Mr. Kloote: I so move, your Honor. Mr. Kahn has indicated to me that he is licensed to practice law in the State of Illinois and I have his address as 7 S. Dearborn in Chicago 60603, and I would move that he be admitted to practice in this court for purposes of this case.
“Judge White: Alright, the motion is granted and the record may show for purposes of preliminary examination on motion of the prosecuting attorney that Mr. Alan Kahn, attorney from Chicago, Illinois, be permitted to practice before this court and represent Br. Bruinsma at this time * * * ,”1
Following the preliminary examination the magistrate made appropriate findings and orders binding defendant over for trial. On October 13, 1969, a notice regarding pretrial and trial was sent. The notice advised that the pretrial conference would be held on November 20, 1969, and that the jury trial would be set for December 9, 1969.2 On December 9, 1969, the trial was held and the defendant, Dirk Bruinsma, was present in open court. The record of the trial states that “Mr Bruinsma appeared in pro per, his counsel, Mr. Alan C. Kahn (not present) and Mr. Leon Buer of counsel [present]”. The verdict of the jury was “guilty as charged”. A motion for new trial was timely filed based on the grounds [172]*172that the trial court abused its discretion by denying defendant’s request for a continuance and that defendant was denied effective assistance of counsel. The motion was denied by the trial court. On May 11, 1970, Dirk Bruinsma was sentenced to a term of 20 to 21 years imprisonment, the 20-year minimum sentence being mandated by the statute. MCLA § 335.152 (Stat Ann 1957 Rev § 18.1122).
I.
The facts and circumstances relative to the issues on appeal are developed in a pretrial colloquy between defendant, Mr. Buer,3 and the court. The colloquy took place before the court, outside the presence of the jury, on the morning of the commencement of the trial. The record discloses the following:
“Mr. Probert [Assistant Prosecutor]: If the court please, this is case No. 13,308, People of the State of Michigan v. Dirk Bruinsma. Today is the day set for trial of this particular matter. The record should indicate that Mr. Bruinsma was originally represented on September 15, 1969, in the 63rd District Court before Judge White by Mr. Alan Kahn, an attorney from Chicago, Illinois. At that time Mr. Kahn indicated that he represented Mr. Bruinsma. When Mr. Bruinsma was arraigned before the circuit court on September 19, 1969, he appeared by himself without benefit of counsel. However, the record indicates at that point that he was still represented by Mr. Kahn of Chicago and that Mr. Kahn [173]*173was going to contact Mr. Leon Buer who would he of counsel in this particular matter.
“Mr. Buer is herewith present before the court today, as is Mr. Bruinsma. In a conversation outside the hearing of the court, Mr. Bruinsma has indicated that Mr. Kahn will not be here today to represent him.
“The Court: Let Mr. Bruinsma speak for himself.
“Dirk Bruinsma: It was like I would like to ask for a motion for continuance.
“The Court: Do you want to tell me why your attorney isn’t here ?
“Dirk Bruinsma: Why he isn’t here? I wasn’t communicating with him enough, I don’t think, which is probably my fault, and I was under the impression that today was a pretrial when it was actually the trial, and that is why he isn’t here today, because I was supposed to have him the balance of the fee prior to my trial date, and when I assumed this was a pretrial I didn’t have that in to him, and consequently he didn’t make it today.
“The Court: You knew the pretrial had already been held?
“Dirk Bruinsma: Well, no, I didn’t. I didn’t know that was the pretrial that was held. I just didn’t.
“The Court: What does the record indicate the date his attorney got notice of the trial?
“Mr. Probert: The record indicates notice was sent by Mr. Dykema October 13,1969, indicating that the pretrial conference for that particular case was to be heard November 20,1969, at 3:15 p.m., and the matter was set for trial before a jury on December 9, at 9:30 a.m.
“The Court: Did you talk to your attorney by telephone last night, Dirk?
“Dirk Bruinsma: Bight.
“The Court: What was the substance of that conversation?
[174]*174“Dirk Bruinsma: Well, then last night is when I came to realize I was going for trial today, and Mr. Kahn was unable to make it today then.
“The Court: You called him, didn’t you?
“Dirk Bruinsma: Eight. Well, first—
“The Court: Why did you call him?
“Dirk Bruinsma: First I called Mr. Buer to find out if my pretrial was at 9:30, and then I found out it was a jury trial, so I immediately called Mr. Kahn and asked him if this was correct or if it was just a misunderstanding, and he said, ‘No, it was my trial today’, and then he said, ‘No, he wouldn’t be able to make it’.
“The Court: How long have you retained Mr. Kahn?
“Dirk Bruinsma: Since about, I think it is about a week prior to my preliminary hearing. I don’t recall the date of the hearing.
“The Court: What is the date of the preliminary hearing?
“Mr. Probert: September 15.
“Dirk Bruinsma: So it would have been somewhere between the 10th and 15th I would have retained him.
“The Court: Have you been in touch with him since that time?
“Dirk Bruinsma: Yes, I have spoken to him since the preliminary, also.
“The Court: There is absolutely no reason why you should not know that your trial was set for today.
“Dirk Bruinsma: I agree that it is probably—
“The Court: You also knew that Mr. Buer was appearing of counsel, did you not ?
“Dirk Bruinsma: Well, he was — I asked Mr. Buer to appear because I think Mr. Kahn said — I don’t recall exactly what was said at the preliminary hearing then because he was from out of the state of Michigan, a Michigan attorney was needed to [175]*175sit in, or I don’t really know what exactly the words were.
“The Court: Do you recall what you said at the preliminary examination?
“Dirk Bruinsma: To Mr. Kahn? Or in relation to what?
“Mr. Probert: At the arraignment?
“The Court: Was it at the arraignment or at the preliminary examination?
“Mr. Probert: There was one statement at the arraignment before the court.
“Dirk Bruinsma: At the arraignment they asked me if I had counsel, and I said, ‘Yes, I had Mr. Kahn’.
“Mr. Probert: He was asked, ‘Is your attorney Mr. Kahn’ by Judge YanderWal, I believe. And he said, ‘Right. Also Mr. Buer. He has to get an attorney from this state.’ ‘Question: Leon Buer, is that his name?’ ‘Answer: Right. I am not sure if that is the one he contacted or not.’ ‘Question: You are instructed to stand mute, and you want a trial, is that it?’ ‘Answer: Yes.’
“The Court: So you, in your conversation with Mr. Kahn at that time you knew he was going to contact Mr. Leon Buer ?
“Dirk Bruinsma: Well, he didn’t know, really, who to work with here, to get for the Michigan attorney, so I told him there was Mr. Buer, and I think I told him there was Mr. G-eil from Muskegon, and then I just, I spoke to Mr. Buer after that, and then I think—
“The Court: You knew subsequent to that that Mr. Buer had been retained as of counsel in your case?
“Dirk Bruinsma: Well, I haven’t given him any money yet, so I don’t know if that means he is retained.
“The Court: That doesn’t answer my question. You knew he had been retained as of counsel?
[176]*176“Dirk Bruinsma: Well, I had spoken to him, and he said—
“The Court: Can you answer that question?
“Dirk Bruinsma: I don’t think I really understand the context of it.
“The Court: You knew [Mr. Buer] was going to appear of counsel in this case ?
“Dirk Bruinsma: Not as my representative, but only as a person sitting in meeting the requirements of having to have a Michigan attorney sit in.
“The Court: All right. We are prepared to go to trial this morning, and you have an attorney representing you, Mr. Bruinsma, and we are prepared to proceed at this point.” (Emphasis added.)
Following this colloquy and the court’s decision to proceed to trial, defendant Bruinsma requested permission to represent himself with “Mr. Buer to give me a little help now and then, if he would like to”. The trial court granted defendant’s request,4 whereupon Mr. Buer made the following statement to the court:
“Mr. Buer: May the record show, your Honor, that I will do everything that I can in this position. It was probably what I was employed for in the first place, only 1 hate to see Mr. Bruinsma representing himself, but he says he is familiar with the case. I certainly am not, so perhaps we can do the job. We will try.”5 (Emphasis added.)
Before we discuss the merits of defendant’s allegations of error, we cannot, confronted with the record before us, ignore the conduct exhibited in the instant case by Mr. Kahn, the attorney from Chicago. This [177]*177Court would be remiss in its duty if we permitted the instant situation to pass unnoticed.
Mr. Kahn is not an attorney licensed to practice law in this state. Nevertheless, the Legislature and the Supreme Court of this state have seen fit to permit attorneys duly licensed in other states to appear and represent clients before Michigan courts under appropriate situations. See MCLA § 600.946 (Stat Ann 1971 Cum Supp § 27A.946); MCLA § 600.916 (Stat Ann 1962 Rev § 27A.916); Johnson v. DiGiovanni (1956), 347 Mich 118. We have no objection to this courtesy extended to out-of-state attorneys, but we must insist upon the recognition of the concomitant duties and their performance. It is an untenable position to argue that nonresident attorneys who are extended the courtesy to practice in this state need not adhere to the same obligations and responsibilities we place upon licensed Michigan attorneys.
An attorney who represents a client cannot withdraw from a case in a manner which leaves his client without notice and without an adequate opportunity to seek other representation. Such conduct violates the canons of professional ethics6 and the established case law of this state.7 To protect against this situation, courts of this state require a motion to withdraw or a notice of substitution of counsel.8
[178]*178In the instant case, Mr. Kahn did not file a motion to withdraw, nor, as far as the record reveals, was sufficient notice given to defendant that Mr. Kahn, would not appear for trial. Instead, Mr. Kahn, for whatever reasons, chose not to appear on the date scheduled for trial.9 Such conduct obstructs the orderly process of criminal procedure. Absent some valid justification, this conduct is indefensible. We shall forthwith refer the conduct of counsel to the Michigan State Bar Association.
We now turn to the merits of defendant’s appeal. The granting or denial of a continuance is governed by court rule, GCR 1963, 503, and statute, MCLA § 768.2 (Stat Ann 1954 Rev § 28.1025). The ruling of the trial court is discretionary and will not be disturbed unless an abuse occurred in the exercise thereof.
Since the instant case involves a criminal proceeding, this Court not only must be satisfied that no abuse of discretion occurred by denying defendant’s request for a continuance, but we must consider whether defendant, under the facts presented, was denied his constitutional right to the effective assistance of counsel. US Const, Am 6; Const 1963, art 1, § 20. Each case in which such issues are raised will necessarily be controlled by the facts presented.
In the instant case we have a young man, 21 years old, charged with the crime which requires a minimum of 20 years’ imprisonment upon conviction. On the record before us, it does not appear that defendant had any prior experience in criminal [179]*179trials. Defendant testified that he was unaware that his trial was to commence on December 9 until he contacted Mr. Buer on December 8, the day before the scheduled trial. Defendant further testified that he had not previously discussed the case with Mr. Buer because defendant simply believed that Mr. Buer’s presence was a formality required when an out-of-state counsel conducted trials in this state. If Mr. .Bruinsma’s testimony is believed, his action in requesting a continuance was made as soon as possible.10 At any rate, this was defendant’s first request for a continuance, and the case had not been previously adjourned.
Mr. Buer not only informed the trial judge in open court that he was not prepared to proceed to trial, but has also filed an affidavit with this Court stating that had he been provided a sufficient opportunity to prepare and familiarize himself with defendant’s ease, the outcome may well have been different. 11 The witnesses subpoenaed on behalf of the prosecution were few, and nothing appears on the record to indicate that the people’s case would have been prejudiced by a continuance.12
[180]*180Considering all the facts presented, and particularly noting the severity of the sentence to be imposed upon a finding of guilt, as well as Mr. Buer’s candid admission to the court that he was not prepared to proceed, we are constrained to hold that the trial court’s denial of a continuance constituted an unsound exercise of discretion13 and denied defendant the fundamental right to effective assistance of counsel.14
We do not mean to imply by our decision herein that a trial judge may not, under appropriate circumstances, proceed to trial. We do suggest, however, that in circumstances similar to those presented in the instant case where the record does not support the conclusion that defendant deliberately attempted to keep from going to trial, the decision not to allow a continuance because of the unsettling effect it would have on the court calendar is necessarily circumscribed by the basic constitutional right to the effective assistance of counsel.
A trial judge presented with a similar situation is not without remedy. The remedy is, in our opinion, sufficient to protect against potential abuses. That is, rather than denying defendant’s motion for a continuance, the court may take such action against derelict counsel as may be appropriate. See MCLA § 600.1701 (Stat Ann 1962 Rev § 27 A-.1701); MCLA § 600.1711 (Stat Ann 1962 Rev 27A.1711).
[181]*181The Michigan Supreme Court recently addressed itself to this problem in People v. Matish (1971), 384 Mich 568, 572, wherein the Court quoted with approval from Arthur v. The Superior Court of Los Angeles County (1965), 62 Cal 2d 404 (42 Cal Rptr 441, 398 P2d 777):
“When an attorney fails to appear in court with his client, particularly in a criminal matter, the wheels of justice must temporarily grind to a halt. The client cannot be penalised, nor can the court proceed in the absence of counsel. Having allocated time for this case, the court is seldom able to substitute other matters. Thus, the entire administration of justice falters. Without judicious use of contempt power, courts will have little authority over indifferent attorneys who disrupt the judicial process through failure to appear.” (Emphasis added.)
II.
But even if this conviction did not require reversal for the reasons previously stated, I do not believe that the statutory requirement that a 20-year minimum sentence be imposed in this case can pass constitutional muster.
Ordinarily judicial restraint would dictate that this opinion not address itself to the question of the constitutionality of the statute. But two reasons exist for consideration of this issue. First, although two panels from this Court have upheld the constitutionality of the penalty imposed under this statute,15 both cases are presently before the Michigan Supreme Court.16 To the extent that the judges of [182]*182this Court are not in complete agreement on this issue, the writer of this opinion feels duty hound to make known his views. Secondly, I take judicial notice of the fact that defendant, if retried and convicted under the statute, would still face a mandatory minimum sentence of 20 years imprisonment.
The Eighth Amendment of the United States Constitution, as well as art 1, § 16 of the Michigan Constitution, forbids the infliction of cruel and unusual punishments. Normally the Eighth Amendment is regarded as a bar only to barbarous methods of punishment — whipping, torture, and the like. Powell v. Texas (1968), 392 US 514 (88 S Ct 2145, 20 L Ed 2d 1254); Louisiana, ex rel. Francis, v. Resweber (1947), 329 US 459 (67 S Ct 374, 91 L Ed 422); Jackson v. Bishop (CA 8, 1968), 404 F2d 571; Comment, 77 Harv L Rev 1071 (1964); Note, 79 Harv L Rev 635 (1966).
There is, however, authority for the proposition that quantitatively excessive sentences may constitute cruel and unusual punishment.17 Justice Douglas, concurring in Robinson v. California (1962), 370 US 660, 676 (82 S Ct 1417, 1425; 8 L Ed 2d 758, 768), stated:
“The question presented in the earlier cases concerned the degree of severity with which a particular offense was punished or the element of cruelty present. A punishment out of all proportion to the offense may bring it within the ban against ‘cruel and unusual punishment.’ See O’Neill v. Vermont, 144 US 323, 331 (12 S Ct 693, 696; 36 L Ed 450, 455).” (Emphasis added.)
[183]*183In Weems v. United States (1910), 217 US 349 (30 S Ct 544, 54 L Ed 793), a Phillipine official was sentenced to 12 years at aggravated hard labor for falsifying public records. Citing the relatively light sentences for this offense in other American jurisdictions, the Court held that this punishment violated the Eighth Amendment. Subsequently, in Trop v. Dulles (1958), 356 US 86 (78 S Ct 590, 2 L Ed 2d 630), Chief Justice Warren observed that
“The basic concept underlying the Eighth Amendment is nothing less than the dignity of man * * * . The Amendment must draw its meaning from the evolving standards of decency that mark the progress of a maturing society.” (Emphasis added.)
I am satisfied that a mandatory minimum sentence of 20 years for the sale of marijuana, regardless of quantity, is, in light of the “evolving standards of decency”, a cruel and unusual punishment for first offenders.
Clearly, it is unusual for anyone to stand trial on the charged offense of sale of marijuana. The mandatory minimum 20-year sentence is so completely out of proportion to the wrong done society that it has become the almost universal practice to offer — indeed to urge — offenders charged with the sale of marijuana to plead guilty to some lesser offense so that the mandatory minimum sentence need not be imposed with the result that it is “unusual” for anyone, even the most hardened offenders, to be sentenced for such a long term; most are sentenced to relatively short terms and many are put on probation.18
[184]*184When the 20-year minimum sentence for the sale of narcotics was established the Legislature did not differentiate between the sale of hard narcotics, e.g., heroin, and the sale of marijuana.19 Since the establishment of the 20-year minimum sentence, scientific investigations have put in question the validity of the assumptions that marijuana, like heroin, is habit forming and that marijuana like heroin, is harmful or, if harmful, anywhere nearly as harmful as the use of heroin and other hard drugs. While all the returns are not in, it does seem clear that there is a significant difference between selling marijuana and selling heroin.20
Although I do not think that it is sound legislative policy to prescribe a minimum sentence and thereby to eliminate altogether judicial and parole board discretion, I would not be prepared to say that a minimum sentence for the sale of hard narcotics is cruel and unusual in light of evolving standards of decency. But, in light of new knowledge acquired regarding the effects of the use of marijuana, and in light of the widespread use of marijuana by otherwise law-abiding citizens, it is manifestly cruel and unusual to impose a minimum 20-year sentence [185]*185for the sale of marijuana, a sentence which is considerably higher than that generally imposed for such serious offenses as second-degree murder, robbery armed, rape, and kidnapping.21
Not only do I believe that the statute is unconstitutional for the reasons pointed out, but it is also wrong in theory and dangerous in practice. The irreparable harm caused by the prolonged sentence cannot be overemphasized. The present statute results in a lamentable failure to discriminate between large-scale pushers of hard narcotics and the individual who merely sells or gives a marijuana cigarette to an acquaintance. See Michigan Revised Criminal Code § 6015, Committee Commentary (Pinal Draft, 1967).
The present statute, by requiring a minimum sentence of 20 years, is at odds with the existing philosophy for sentencing convicted offenders under our criminal laws. With the exceptions of mandatory life imprisonment for convictions of first-degree murder and treason, no other criminal statute requires such a severe minimum sentence. In fact, [186]*186the remaining criminal statutes are predicated upon a theory designed to permit the sentencing court to consider the individual before him, the nature of the offense, and the circumstances surrounding the criminal conduct. While the sentencing scheme usually provides a statutory maximum for the most egregious offenses, it assigns to the sentencing judge the task of determining what lesser sanctions, if any, will serve the interest of society without unjustly penalizing the offender.
MCLA § 335.152 (Stat Ann 1957 Rev § 18.1122) requires the sentencing court to ignore the individual offender before it and to impose, as a minimum, a 20-year prison term. The imposition of a statutory minimum, which precludes the offender from receiving the benefit of any special equity or mitigating circumstances which might otherwise result in a less severe sentence, is itself a sign of unusual severity. The sentencing judge in the instant case made known for the record his opinion of this requirement:
“I want to make it known that I am not in favor of this minimum sentence of 20 years, and I will write a letter to the corrections commission to see that you are released at the earliest possible time insofar as the law permits, giving you all the credit for ‘good time’ if you do behave yourself at the institution.”
What is the relevance, rightness, or responsiveness of the statutory requirement that an offender, who sells, dispenses, or otherwise disposes of any quantity of marijuana, be sentenced to a minimum of 20 years’ imprisonment, regardless of the circumstances? Such a situation is not only incompatible with all other criminal statutes, but is totally [187]*187inconsistent with any recognized legitimate aims of modern criminal jurisprudence.
We cannot and should not remain either silent or passive to this statutory injustice. To remain silent would destroy both the faith and confidence of many of our citizens in their justifiable belief that our laws should be based in part on a foundation of relevance, rightness, and responsiveness.
Reversed and remanded.
