The name sounds harmless enough, but doctors say don't be fooled -- the drug known as "Molly" can be fatal.
Molly is a form of MDMA (3,4-methylenedioxy-N-methylamphetamine), the drug that is used in ecstasy. Molly usually refers to MDMA in a powder or crystalline form, and it's marketed as a "pure" form of ecstasy -- a common misconception, since it is often mixed with highly addictive drugs like cocaine, meth and bath salts.
At a party with friends, 15-year-old Diane met Molly for the first time.
"Some people were taking it, and then I took some," she said. "I popped one then snorted a line of another one."
Molly is landing more people in emergency rooms because it is often laced with other drugs and substances.
"What they actually took is not what they thought they took," said emergency physician Dr. Timothy Dougherty.
Molly is an amphetamine, a stimulant that raises blood pressure and body temperature. It can lead to seizures, kidney failure, heart attack and even death.
"The probability of you dying -- it's just not worth it," said Dr. Dougherty.
MDMA is highly addictive. The price ranges from $8 to $25 per pill. Though the drug can create euphoric feelings, the crash that follows is equally dramatic.
