Bennies

Bennies is a slang term used to describe "Benzedrine" off of the street and/or “Benadryl”. Ironically enough the drugs are very different. Benzedrine is similar to that of Methamphetamine. While Benadryl gives the user a nightmarish high with lots of cramps and visual effects.

Dude… I haven’t slept in 3 days, these Bennies got me awake asf.
