A guy who acquires a hot peice of ass due only to his access to free drugs. Most often these are drugs dealers and tour rats commonly found in the jam band scene (Phish, Grateful Dead, The Disco Biscuits, etc.)

Similar to a Sugar Daddy.
Dude, that chick is smokin hot...What the hell is she doing with that creepy old guy?

Oh thats her Drug Daddy, she's fucking him cause he gives her free acid and molly.

Basically like a sugar daddy but he provides you with quality kush instead
I saw my drug daddy today and he put me on some good shit, except I had to give him head for it. UGHHHH
