What is Blue Dolphin ecstasy?
From CNN’s Katherine Dillinger
Cassie Ventura testified today that she took drugs during “Freak Offs” with Sean “Diddy” Combs, including a version of ecstasy called Blue Dolphin.

Ecstasy, also known as molly or MDMA, is part of a class of psychoactive drugs that produce experiences of emotional communion, relatedness and openness. Some users report having less of an urge to eat, drink or sleep, contributing to its use as a party drug.

The drug is taken orally, usually in tablets or capsules, and may be made in different strengths or combined with other drugs. Many manufacturers create their tablets in specific colors or stamp them with certain symbols as a way of branding their products, building confidence in the contents and increasing their appeal to users. Popular symbols include alligators, trees, doves and dolphins, as well as logos like Chanel, Honda and Superman. Blue Dolphin is a blue MDMA tablet stamped with a dolphin symbol.
