'Molly' is a purer, powdered  form of Ecstasy chemically known as methylenedioxymethamphetamine (MDMA). It has been around for decades. It has lately surged in popularity with college students, and is being name-checked by mainstream artists ranging from Kanye West and Rick Ross to Miley Cyrus and Madonna. Molly can be taken orally in powder, tablet or capsule form. The effects, which include a sense of increased energy, euphoria and empathy, can last from three to six hours after ingestion. It was first created as a diet drug in 1914, and in the 1970s was used by doctors as an aid in psychotherapy. In the 1980s and 1990s it burst upon the club scene as a party drug. Today, the drug is currently in clinical trials as a potential aid to treat post-traumatic stress disorder as well as anxiety in terminal cancer patients.

Colorado and Washington state have legalized marijuana.

Alaska, California, Oregon, Nevada, Maine, New Hampshire, Massachusetts, Connecticut and Rhode Island have both medical marijuana and decriminalization laws.
