Defendant’s sole assignment of error is based upon his exception to the court’s allowance of certain questions propounded to defendant on cross-examination. Defendant does not argue that a defendant in a criminal case who testifies in his own behalf may not be subjected to impeachment by questions related to specific acts of criminal, degrading or disparaging conduct; however, he argues that the questions in this case did not deal with specific acts. That portion of the cross-examination to which defendant excepted proceeded as follows:
“Q. How many times have you smoked marijuana? Objection. Sustained as to the form of the question.
Q. How many times have you possessed marijuana before April 4, 1973, and one year prior to that time? Objection. Overruled.

Chief Justice Bobbitt addressed himself to the problem of the scope of cross-examination of a defendant in a criminal trial in State v. Williams, 279 N.C. 663, 675, 185 S.E. 2d 174, 181 (1971), where he said:.
“It is permissible, for purposes of impeachment, to cross-examine a witness, including the defendant in a criminal case, by asking disparaging questions concerning collateral matters relating to his criminal and degrading conduct. State v. Patterson, 24 N.C. 346 (1842) ; State v. Davidson, 67 N.C. 119 (1872) ; State v. Ross, 275 N.C. 550, 553, 169 S.E. 2d 875, 878 (1969). Such questions relate to matters within the knowledge of the witness, not to accusations of any kind made by others. We do not undertake here to mark the limits of such cross-examination except to say generally (1) the scope thereof is subject to the discretion of the trial judge, and (2) the questions must be asked in good faith.”
See also State v. Black, 283 N.C. 344, 196 S.E. 2d 225 (1973), and State v. Mack, 282 N.C. 334, 193 S.E. 2d 71 (1972) .
In the case at bar, defendant, who was shown to be an outstanding high school senior, admitted possession and distribution of the marijuana; he contended, however, that his actions resulted from the continued insistence of an undercover agent who proved to be a High Point police officer. Defendant testified that eventually he was persuaded to buy the marijuana from a third party and to resell it to the officer, merely as a favor to the officer. In view of those contentions, we think the trial court clearly was justified in permitting the district attorney to “sift the witness” in order to show the defendant’s involvement in violating the narcotic laws. The questions asked defendant related to matters within his knowledge; and there is nothing to indicate that the questions were not asked in good faith. We hold that the trial court did not abuse its discretion.
*22For the reasons stated, we find
No error.
