KAPLAN, J.

The defendant was indicted for trafficking in cocaine of a weight of one hundred grams or more but less than two hundred grams (G.L.c. 94C, § 32E[ b][2], as appearing in St. 1983, c. 571, § 3). Under a search warrant, the police seized drugs and other things found in a designated apartment and a related hall closet or locker. Before trial the defendant moved to suppress the evidence seized, and to suppress also certain statements made by the defendant during the execution of the warrant. The first motion failed; the second was allowed in part. At trial the jury brought in a verdict of guilty of trafficking as charged. The defendant appeals from the judgment of conviction. Also under appeal is the denial of a postverdict motion for a new trial based upon an alleged conflict of interest on the part of defense counsel.

1. The judge left to the jury the trafficking in 100-200 grams and the lesser included offense of simple possession; he did not put to the jury, as additional lesser included offenses, trafficking in 28-100 grams or possession with intent to distribute. The defendant contends that the omission was error. We must set the stage.

Seized under the warrant in the apartment was a bag with a small residue of cocaine, and from the closet, 111.82 grams of eighty-six percent pure cocaine in "rock" form. Also seized were paraphernalia of the narcotics trade, which need not be described.

The defendant took the position at trial with respect to the rock cocaine that he did not possess or control it for any purpose, whether for trafficking or personal use. However, he attempted to show that he was a cocaine user of up to two grams a week.

The defendant objected to the judge's omission to charge in accordance with the defendant's proposed instruction No. 1 (as well as Nos. 2 and 3). No. 1 was entitled "Instruction on `Lesser Included Offenses'" and set out proposed charges on the three offenses short of the larger trafficking offense named in the indictment. The defendant referred the judge to the proposed instruction by number. He did not address the judge on the grounds of the instruction or, correspondingly, the grounds of the objection to the court's failure to give the instruction. Thus the defendant appears to have done less than is called for by Mass.R.Crim.P. 24(b), 378 Mass. 895 (1979), which requires that counsel specify both "the matter to which he objects" and "the grounds of his objection." See Commonwealth v. Keevan, 400 Mass. 557, 563-564 (1987); Commonwealth v. Maskell, 403 Mass. 111, 115 (1988).

The defendant gets around to stating his "grounds" in his brief on appeal. There he indicates that, in his conception of trafficking by possession with the intent to distribute, the Commonwealth is bound to prove, out of the total quantity of the drug the defendant possessed, what amount thereof he intended to distribute, and it is that amount which fixes the range or bracket of the trafficking, e.g., whether 28-100 or 100-200. Thus, in the defendant's view, the jury should have been asked to attempt to consider (even despite the defendant's disclaimer of possession of the rock) what part of the rock was intended to be consumed by the defendant himself, and to deduct that amount from the 111.82 grams: thus an instruction would be in order as to the lesser offense involving 28-100 grams.

We think this interpretation of the statute is erroneous and the quantity of rock possessed by the defendant fixed the trafficking bracket so long as there was an intent to distribute some part of it. The language of the statute easily permits that interpretation, and it is reason for accepting the reading that the defendant's contrary interpretation would create great practical difficulty in the enforcement of the law. We cannot suppose that a Legislature which has successively increased the penalties for trafficking would be content with the defendant's interpretation or its practical result. The maxim that penal statutes are to be strictly construed does not mean that an available and sensible interpretation is to be rejected in favor of a fanciful or perverse one. See Edgartown v. State Ethics Commn., 391 Mass. 83, 90 (1984) (quoting from Simon v. Solomon, 385 Mass. 91, 102-103 [1982]: the maxim "is a guide for resolving ambiguity, rather than a rigid requirement that we interpret each statute in the manner most favorable to defendants"); United States v. Restrepo, 676 F. Supp. 368, 372 (D. Mass. 1987), aff'd, 867 F.2d 605 (1st Cir. 1988) ("I must not construe the criminal statute so strictly as to defeat the obvious intention of the legislature. . . . Nor may I manufacture ambiguity to invoke the rule of lenity so as to defeat that intent"). And see the discussion of the maxim in Estridge and Frickey, Cases and Materials on Legislation: Statutes and the Creation of Public Policy 658-676 (1988).

There was no contest about the weight of the rock taken from the closet; the jury may be taken to have found that the defendant possessed that weight and intended to distribute at least a part of it. What has been said supports the judge's omission to charge on the 28-100 grams provision of the statute as a lesser included offense. So also, the weight being uncontested, there was no proper basis for charging on possession with intent to distribute, that is, possession of an indeterminate weight. See Commonwealth v. Egerton, 396 Mass. 499, 504 (1986).

2. Other claims of error are without merit. The search warrant was adequately supported by the affidavits presented to the magistrate; and there was no basis for suppressing the evidence found. The judge's ruling on the motion to suppress statements was correct. There was no error in the trial judge's admitting expert testimony regarding certain practices of the narcotics trade. The pretrial ruling with regard to an alleged conflict of interest was correct, and a new trial motion for the same alleged reason was properly denied.

Judgment affirmed. Order denying motion for a new trial affirmed.
