¶1Defendant was convicted of a violation of the Georgia Controlled Substances Act. Held:
¶2Defendant complains that the court erred in allowing *180two witnesses to testify that an arrest warrant was pending against a defense witness. No objection was interposed by the defendant when these questions were asked. A failure to object at trial constitutes a waiver of any objection to evidence. Gattlen v. State, 134 Ga. App. 71 (213 SE2d 173).
¶3Judgment affirmed.
