Cocaine
Cocaine is an extremely popular drug on the party circuit, and is well known for its association with the rich and famous (because only they could afford to maintain a habit). Unfortunately, a new form of cocaine, crack, is significantly more accessible and has ruined the lives of many.
A stimulant that works on dopamine, cocaine produces feelings of euphoria, energy and excitement. The crash can be nasty, however, and potential side effects include paranoia and delusions that bugs are crawling over your skin. Not to mention its exceptionally high rates of addiction.
