Colors awhirl. Imaginary sounds loudly humming in your ears. Inanimate objects suddenly glowing with new life. No, we're not on drugs, but we can't say the same for the people in the following movie scenes. And while Complex certainly doesn't condone drug use (those D.A.R.E. presentations really got to us), we do approve of any film than can take us on an effective "trip" while we're still lounging lazily on our couches.

Magic Trip, a new documentary in theaters today, follows infamous author Ken Kesey (One Flew Over The Cuckoo's Nest) on his LSD-induced adventures across America in 1964. But if you're not quite ready to move beyond your bed, we've got you covered. The way we see it, there are two types of substance-abuse scenes: ones that merely show people on drugs, and others that make you feel like you, the viewer, are the one on drugs.

We prefer the latter. So sit back and trip vicariously through our favorite on-screen fiends in the 10 Greatest Drug Scenes In Movies.
