Appellant was charged in an eight-count indictment with possession and distribution of cocaine, in violation of 21 U.S.C. § 841(a)(1), and with using communication facilities to facilitate dis- ■ tribution in violation of 21 U.S.C. § 843 (b). The jury returned a verdict of guilty on all eight counts.
Although appellant raises thirteen assignments of error, only three warrant discussion:
1. admissibility of tape-recorded telephone conversations between appellant and a government informant;
2. admissibility of evidence regarding prior purchases of cocaine; and
3. propriety of limitation on cross-examination of a government witness.
Appellant contends that the taping of conversations between government informant Teply and himself was an unreasonable invasion of privacy, violative of his Fourth Amendment rights. Teply consented to the taping, thus eliminating any constitutional overtones. United States v. White,
The second assignment of error involves the introduction of evidence showing purchases of cocaine by appellant prior to the sales alleged in the indictment. Appellant argues that such evidence was irrelevant and prejudicial. The evidence was relevant to the issues of the case since it tended to show possession by appellant of quantities of co *407 caine substantially in excess of his needs as a practicing physician.
Finally, appellant claims that he should have been permitted to inquire into the specific address of the informant. However, Smith v. Illinois,
The court finds no merit in any of appellant’s other contentions and affirms the conviction on all counts.
Affirmed.
