¶1MEMORANDUM DECISION.
¶2The Defendant, Brian P. Glynn, was convicted in Superior Court (York County) of unlawful possession of a scheduled drug, 17-A M.R.S.A. § 1107, at a bottle club in York on June 23, 1979.1 He appeals from that judgment of conviction, asserting that the Superior Court erred in admitting a police officer’s opinion testimony as to the quantity of cocaine in the Defendant’s possession being a “useable amount” within the meaning of that statute and that the evidence was insufficient to sustain a conviction because, he contends, the State failed to prove beyond a reasonable doubt that he possessed “a useable amount” of the drug.
¶3Neither argument has merit.
¶4On the facts of this case concerning the experience and qualification of the witness, the admission of his opinion testimony was within the sound judicial discretion of the presiding justice. He did not abuse that discretion.
¶5As to the sufficiency of the evidence, a chemist’s certificate stating that “the white powder contains cocaine” was admitted without objection, and, by his answers *800to questions, the arresting officer opined that the quantity of the powder was sufficient to be inserted in one’s nose. This case, then, is indistinguishable from State v. Bonney, Me., 427 A.2d 467 (1981), decided only a few months ago, in which our Court declared that once consumability of the scheduled drug is demonstrated and the possession of a detectable amount is proved, the factfinder may infer the possession of “a useable amount.”
¶6The entry, therefore, will be:
¶7Appeal denied.
¶8Judgment affirmed.
¶9All concurring.
