Taken together, the evidence in the record tends to show a connection between Jamison and the contraband sufficient to prove that he knowingly shared with his brother the power and intention to exercise dominion or control over the cocaine mixture. See Glenn v. State, 251 Ga.App. 336, 337–338(1), 553 S.E.2d 323 (2001). As for the contention that Jamison did not have constructive possession of the mixture found in the second bedroom—even if he did have constructive possession of the mixture found in the kitchen—it appears to be premised on the notion that the second bedroom was that of Royrecaus.

The State may present expert testimony that a specific amount of drugs is greater than a person would possess for personal use. See Glenn v. State, 251 Ga. App. 336, 338-339(2) ( 553 S.E.2d 323) (2001). While Agent Hemphill was not officially tendered as an expert witness, Bussey did not object to his testimony.
