Watch one of the greatest "drug" movies of all time.  I hate to call it a drug movie, but it kind of is.  Watch Fear and Loathing in Las Vegas online.

Fear and Loathing is based on the book by Hunter S. Thompson and stars Johnny Depp as the main character.

Here's a brief synopsis of the book and movie from wikipedia (it explains it better than I can):

Fear and Loathing in Las Vegas: A Savage Journey to the Heart of the American Dream is a novel by Hunter S. Thompson, illustrated by Ralph Steadman. The book is a roman à clef, rooted in autobiographical incidents. The story follows its protagonist, Raoul Duke, and his attorney, Dr. Gonzo, as they descend on Las Vegas to chase the American Dream through a drug-induced haze. The novel first appeared as a two-part series in Rolling Stone magazine in 1971, was printed as a book in 1972, and was later adapted into a film of the same name in 1998 starring Johnny Depp and Benicio del Toro.

It is a pretty amazing movie--I remember watching it one summer after high school and it sort of blew my mind.  I couldn't believe how strange and weird Fear and Loathing was, but it also seemed to affect me in terms of how I saw the world through this one man's crazy, irreverent perspective.  Hunter S. Thompson was an interesting writer with a lot to say.
