Den of Geek! compiled their top 50 favorite movie scenes "where the effects of drug-taking are depicted." When possible, they've also embedded YouTube clips of the scenes (hence the slow load of the pages). Their top five scenes are from:
1. Rosemary's Baby
2. The Big Lebowski
3. Fear and Loathing in Las Vegas
4. Altered States (seen above, with a new trance soundtrack by Bedrock)
5. The Matrix
