A grand jury in Essex County returned indictments against the defendant for involuntary manslaughter, G. L. c. 265, § 13 (1988 ed.), and for the unlawful distribution of a class A controlled substance, namely heroin, G. L. c. 94C, § 32 (a) (1988 ed.). The indictments stemmed from testimony before the grand jury of the defendant’s sale of heroin to Grace Randazza and her death after use of the heroin. The defendant filed a motion to dismiss the manslaughter indictment on various grounds, including an assertion that the evidence presented to the grand jury was insufficient to justify the return of an indictment for involuntary manslaughter. See
Commonwealth
v. McCarthy,
“1. Was the evidence presented to the Grand Jury sufficient to support an indictment for manslaughter under the principle of ‘unlawful act-manslaughter’?
“2. Was the evidence presented to the Grand Jury sufficient to support an indictment for manslaughter under the principles of Commonwealth v. Welansky,316 Mass. 383 (1944) (wanton and reckless conduct)?” 2
We allowed a joint application for direct appellate review. We conclude that the defendant cannot be charged on the theory of unlawful-act manslaughter, but that the evidence before the grand jury is sufficient to support his prosecution under
Commonwealth
v.
Welansky,
*781 The evidence presented to the grand jury, viewed in the light most favorable to the Commonwealth, indicated the following. On the afternoon of October 31, 1986, Christine Murphy Pratt, who was driving her automobile in Gloucester, picked up Peter Gabriele. Gabriele told Pratt that he was looking for heroin. Pratt advised Gabriele that the defendant had “some dope.” Gabriele knew the defendant as a heroin dealer and had previously purchased heroin from him.
Pratt and Gabriele drove to a café where they picked up the defendant and Randazza. After Randazza and the defendant entered the vehicle, there was a conversation about purchasing heroin. The defendant told Randazza that he had “Seven-Life” heroin which was “very potent stuff [and] that she shouldn’t fool around with it.” The defendant told Randazza not to “do a whole one.”
Pratt dropped Gabriele and Randazza at a “sub shop” and then drove the defendant a short distance to his house. The defendant quickly entered his house and returned to Pratt’s car. On the return trip to the sub shop, Pratt purchased one bag of “Seven-Life” heroin from the defendant for $50.
Randazza and Gabriele were in the sub shop when the defendant returned. Randazza said to Gabriele, “[H]e’s here, give me the money.” Gabriele witnessed the defendant hand Randazza three bags of “Seven-Life” heroin. Randazza then handed Gabriele two bags for which he had paid $100. She kept one bag for herself.
Randazza was known to the defendant and to Pratt as a heroin user, and to Gabriele as a heroin addict. The defendant acknowledged that Randazza could not handle a full bag of “Seven-Life” heroin. The defendant further acknowledged that “he had helped [Randazza] from overdosing” on several occasions. The defendant also admitted to the police that he was aware of- another overdose of “Seven-Life” heroin which had almost resulted in an individual’s death.
Randazza returned home between 2:30 p.m. and 3:30 p.m. At approximately 5:30 p.m., a relative of Randazza found her unconscious in a bedroom in his home. His attempt at resuscitation was unsuccessful. Found near Randazza were a hy *782 podermic needle, syringe and “cooker spoons,” which were turned over to the police. An analysis of the spoons revealed heroin residue; no controlled substance was found in the needle and syringe.
Randazza was transported to the hospital where a nurse retrieved a glassine bag labeled “Seven-Life” from her dungaree pocket. The glassine bag was turned over to the police; analysis revealed that it contained heroin residue.
An autopsy was performed on the body of Randazza. According to the pathologist’s report, Randazza died of “pulmonary congestion as a result of combined drug use.” The combined drugs were heroin and alcohol. Although the alcohol alone would not have caused her death, according to the pathologist, the heroin found in her body was a lethal dose.
1.
Unlawful-act manslaughter.
The first reported question asks whether the evidence presented to the grand jury was sufficient to support the defendant’s prosecution for manslaughter under the theory of so-called unlawful-act manslaughter. The indictment, however, reads in relevant part as set forth below,
3
and is framed in terms of whether the defendant committed manslaughter under the principles set forth in
Commonwealth
v.
Welansky,
A defendant cannot be prosecuted for an act which was not a crime when it was performed,
Lembersky
v.
Parole Bd. of the Dep’t of Correction,
The parties, however, have briefed and argued questions about the state of certain aspects of involuntary manslaughter after the decision in
Commonwealth
v.
Matchett,
There is no statutory definition of manslaughter in Massachusetts; its elements are derived from common law.
Commonwealth
v.
Godin,
The present state of unlawful-act manslaughter suffers from the same problem that affected second degree felony murder prior to the
Matchett
decision. In
Commonwealth
v.
Matchett, supra
at 492, we moderated our previous common law felony-murder rule, which automatically imposed “criminal liability for homicide on all participants in a certain com
*785
mon criminal enterprise if a death occurred in the course of that enterprise.”
Id.
at 502, quoting
Commonwealth
v.
Watkins,
As was the case under our common law felony-murder rule prior to the
Matchett
decision, a defendant presently may be found guilty of unlawful-act manslaughter if a death is caused by his commission of a misdemeanor or other unlawful act, without regard to the nature of the act or the dangerousness of the defendant’s conduct. The Supreme Judicial Court of Maine in
State
v.
Pray,
It is not surprising, therefore, that unlawful-act involuntary manslaughter has been severely criticized. LaFave & Scott, Criminal Law 602 (1972); Wilner, Unintentional Homicide in the Commission of an Unlawful Act, 87 U. Pa. L. Rev. 811 (1939). The principle that underpins the offense perpetuates the notion of constructive crime which has been generally discredited. The Model Penal Code rejects the concept of unlawful-act manslaughter altogether. Under the Code, a defendant’s conduct must be reckless before he can be punished for manslaughter, Model Penal Code and Commentaries, Official Draft & Revised Comments 210.3(l)(a) (1980); and the Code establishes a separate crime of criminally negligent homicide. Model Penal Code, supra at § 210.4. Some States have adopted this approach. 7 Other States have modified their manslaughter law by requiring, either by case law or statute, that the underlying unlawful act meet some minimum standard of seriousness. Some of those States focus on the perpetrator’s mental state and require *787 recklessness or some form of negligence. 8 Others focus on the risk to human life or safety inherent in the underlying act, 9 or use an approach which is an amalgam of one or more of the above. 10
We believe that unlawful-act manslaughter should be abandoned in Massachusetts except for appropriate cases which are based on the principle that a battery that causes death is manslaughter. The latter principle has long been part of our common law and has been applied, as the
Sheppard
case illustrates, see note 6,
supra,
in circumstances in which the defendant is, or should be, cognizant of the fact that the battery he is committing endangers human life. Apart from this principle, unlawful-act manslaughter has
*788
been rarely used as a basis for prosecution, and then in cases that are factually eccentric.
11
Any effort to redefine the basis of culpability for unlawful-act manslaughter in terms of the various standards described above, see notes 8, 9, and 10,
supra,
would cast the offense in terms of a standard which comes close to duplicating the standard set forth in
Commonwealth
v.
Matchett, supra
at 508, for felony-murder (conduct involving a “conscious disregard of the risk to human life”), or the standard for implied malice in murder described in
Commonwealth
v.
Starling,
There is no doubt of the desirability of legislative consideration of the homicide law with a view toward simplification and modernization. See Commonwealth v. Starling, supra at 428-429. However, in the absence of definitive action by the Legislature, we must bring our involuntary manslaughter law in line with the Matchett decision. See LaFave & Scott, Criminal Law 602 (1972 ed.). For the reasons stated above, *789 a person henceforth may be prosecuted for involuntary manslaughter only for causing an unintentional death (1) during the commission of wanton or reckless conduct, as defined in Commonwealth v. Welansky, supra, or (2) during the commission of a battery, under the principles set forth in Sheppard, supra, and the other cases cited therein.
For the reasons previously stated, the answer to the first reported question is “no.”
2.
Welansky manslaughter.
The second reported question asks whether the evidence before the grand jury supports the defendant’s indictment for manslaughter under the principles set forth in
Commonwealth
v.
Welansky,
We inquire whether the evidence presented to the grand jury was sufficient to support the defendant’s indictment for involuntary manslaughter under the
Welansky
theory as described above. The defendant has not yet been tried on this charge, so we are not concerned with whether sufficient evi
*790
dence exists to warrant a finding of his guilt beyond a reasonable doubt. Rather, we consider only whether the information before the grand jury was adequate to establish his identity and probable cause to arrest him for the crime charged. See
Commonwealth
v.
McCarthy,
Here, evidence was presented that the defendant committed the felony of distributing heroin (in fact a potent form of the substance known as “Seven-Life” heroin). 12 The distribution of heroin is a particularly serious crime. See G. L. c. 94C, § 32 (a). Between 225 and 315 people in this Commonwealth alone died from heroin abuse during the year ending in March, 1988. Recognizing the critical nature of the heroin use problem, both Congress and our Legislature have placed heroin in the most dangerous category of controlled substances. See 21 U.S.C. § 812 (1982); G. L. c. 94C, § 31 (1988 ed.). This classification reflects a legislative determination that heroin has “a high potential for abuse,” “no currently accepted medical use” in the United States, and lacks “accepted safety” for use even under medical supervision. 21 U.S.C. § 812 (b)(1) (West 1981); G. L. c. 94C, § 3 (1) (1988 ed.). Violation of our statute proscribing heroin distribution carries a severe penalty of up to ten years in prison and $10,000 in fines. See G. L. c. 94C, § 32 (<z) (1988 ed.). Repeat offenders face a mandatory minimum prison sentence of five years, and a maximum of fifteen years. See G. L. c. 94C, § 32 (b) (1989 Supp.).
The New York Supreme Court has aptly described the risks inherent in the defendant’s action. In
People
v.
Cruciani,
The defendant’s contention that the causal link between the heroin sale and Randazza’s death was broken by Randazza’s intervening conduct of injecting herself lacks merit. Intervening conduct that is reasonably foreseeable will not relieve the defendant of criminal responsibility. See
Commonwealth
v.
Askew,
The evidence before the grand jury furnishes probable cause to believe that the defendant committed involuntary manslaughter under the principles stated in the Welansky case. It follows that our answer to the second reported question is “yes.”
Notes
This rule of criminal procedure reads as follows:
“If, prior to trial, or, with the consent of the defendant, after conviction of the defendant, a question of law arises which the trial judge determines is so important or doubtful as to require the decision of the Appeals Court, the judge may report the case so far as necessary to present the question of law arising therein. If the case is reported prior to trial, the case shall be continued for trial to await the decision of the Appeals Court.”
In connection with the report, the Commonwealth was designated the appellant.
The indictment alleges that the defendant “did assault and beat Grace Randazza and by such assault and beating did kill Grace Randazza, in that he did, with wanton and reckless disregard of the probable harmful consequences of his action, distribute to Grace Randazza a controlled substance in Class A of General Laws, c. 94C, § 31, to wit: heroin, and by such action caused the death of Grace Randazza.” In
Commonwealth
v.
Campbell,
4Commonwealth
v.
Adams,
The battery causing death theory of manslaughter is not exactly the same as Welansky manslaughter. In Commonwealth v. Sheppard, supra at 776 n.l, we rejected the defendant’s argument “that a ‘battery’ to be the basis of a conviction of involuntary manslaughter, must first be found to have amounted to ‘wanton or reckless conduct.’ ”
Our recent decision in Commonwealth v. Sheppard, supra illustrates this type of involuntary manslaughter. In that case, the defendant punched the victim in the face causing him to fall backward and hit his head. The victim died as the result of a severe skull fracture. We noted that the trial judge instructed the jury as follows: “you [must] find that the Commonwealth ha[s] proved [that] the defendant punched the victim. Further, there would have to be proof . . . this punching, was harmful. A harmful battery occurs when the touching is done with such violence that harm is likely to result.” 404 Mass, at 777. We then went on to state “[g]iven this instruction, the fact that the defendant was six feet tall and weighed 185 pounds while the victim was only five feet seven inches tall and weighed 125 pounds, the fact that the punch was of sufficient force to cause the victim’s head to hit the street and cause a severe skull fracture and brain hemorrhage, and the evidence that the defendant called the blow a ‘knockout punch’, the jury’s finding of an intentional battery done ‘with such violence that harm [was] likely to result’ was a sufficient basis to support the manslaughter conviction.” Id.
See, e.g., Conn. Gen. Stat. Ann. § 53A-56 (West 1985) (a person who “recklessly causes the death” of another is guilty of second degree manslaughter); N.Y. Penal Law § 125.15 (Lawyers Co-op. 1984) (same); Wis. Stat. Ann. § 940.06 (West Supp. 1989) (person who “recklessly causes the death” of another is guilty of second degree reckless homicide).
These jurisdictions also follow the Model Penal Code in establishing separate statutory crimes to cover homicides caused by criminally negligent behavior. See Conn. Gen. Stat. Ann. § 53a-58 (West 1985); N.Y. Penal Law § 125.10 (Lawyers Co-op. 1984); Wis. Stat. Ann. § 940.08 (West 1982 & Supp. 1989) (negligent use of various enumerated weapons).
The Revised Criminal Code of Massachusetts, proposed by the Massachusetts Criminal Law Revision Commission in 1971, but never enacted, mirrored the Model Penal Code’s approach. Section 3 of the proposed code would have required proof of recklessness before a defendant could be convicted of involuntary manslaughter. Section 5 of that code would have established a new statutory crime of criminally negligent homicide. See Proposed Criminal Code of Massachusetts 96-98 (Lawyers Co-op. 1972).

In addition, there was evidence that the defendant knew he was distributing a highly potent brand of heroin, that Randazza had a low tolerance for the drug and had overdosed in the past, that she could not handle a whole bag of this type of heroin, and that she needed to be warned not to “do a whole one.”
In some States the sale of a dangerous drug has been held to be a sufficient predicate for a felony-murder prosecution. See
People

Poindexter,
