To understand a drug, you need to understand its effects, why people use it, and the risk it poses in terms of both health and criminal penalties.

Marijuana

Marijuana

Marijuana is the most popular and easily accessible illegal drug in the U.S. today. The use of marijuana for both medicinal and recreational purposes is not new. Indeed, the use of marijuana has been documented as far back as 12,000 years ago, making it one of the earliest cultivated crops.

Heroin

Heroin is processed from morphine, a naturally occurring opiate extracted from the seedpod of certain varieties of poppy plants. The opium poppy has been cultivated for more than five thousand years for a variety of medicinal uses.

MDMA (Ecstasy, Molly)

MDMA, often referred to as “ecstasy” or “molly”, is short for 3,4 methylenedioxymethamphetamine, a psychoactive drug derived from safrole oil. MDMA produces effects that resemble both stimulants and psychedelics, as well as its signature effect: a feeling of connectedness.
