CARLEY, Judge.
Appellant appeals from her conviction of three counts of violating the Georgia Controlled Substances Act.
1. The general grounds are raised. Appellant specifically contends that the State failed to prove that there was any sale of controlled substances.
The evidence showed that, on three separate occasions, appellant provided a substance which proved to be marijuana to an undercover narcotics agent in exchange for a sum of money. Each of these transactions constituted a sale of contraband. Johnson v. State, 154 Ga. App. 353 (1) ( 268 S.E.2d 406) (1980). See also Robinson v. State, 164 Ga. App. 652, 653 (1) ( 297 S.E.2d 751) (1982). The evidence was sufficient to enable a rational trier of fact to find beyond a reasonable doubt that appellant was guilty of the crimes charged. Jackson v. Virginia, 443 U.S. 307 (99 SC 2781, 61 L.Ed.2d 560) (1979); Johnson v. State, supra; Sankey v. State, 167 Ga. App. 224 ( 306 S.E.2d 357) (1983).
2. Appellant further enumerates as error the trial court's refusal to give her requested charge on the statutory definition of marijuana. Since there was no evidence whatsoever to indicate that the substance in issue was not marijuana, this enumeration is without merit. Branch v. State, 248 Ga. 300, 301-302 (3) ( 282 S.E.2d 894) (1981).
Judgment affirmed. Birdsong, P. J., and Beasley, J., concur.
DECIDED FEBRUARY 1, 1985 — REHEARING DENIED FEBRUARY 25, 1985.
