bud hound 

A person who is particularly deft at tracking down and helping acquire illicit, substances, especially marijuana. Note: He's not a drug dealer, but rather makes the connection between buyer and seller.

I ran out of weed on Friday night, but this bud hound I know came through in a pinch.
