It airs again at 3am tonight, not seeing any other times presently.
Just saw a history of drugs documentary on the History Channel. They
definitely brought a lot of perspective and (obviously) historical
insight into the subject. This documentary was called History Alive:
Cocaine but it actually touched on most common drugs including opium,
heroin, crack, and marijuana. Very interesting & informative. And they
didn't even bust on techno culture.... :) (They're holding out for
History Alive: MDMA)
