SPRINGFIELD, Mo. -- The name may seem innocent, but the drug "Molly" can be dangerous.
Miley Cyrus sings about dancing with Molly in her current hit, and Madonna mentioned the drug at a concert last year.
Three people died at music festivals last week after taking the drug -- known as a pure form of ecstasy -- or MDMA.
"Molly -- that's nothing good," one KOLR10 viewer says. "Every single touch that you make, every light that you see, all your senses are just boosted where it's beautiful. You feel great."
"People use it when they go listen to music, music festivals, raves, things like that, because the effects of it can last hours and it kind of gives them a euphoria," says Sally Gibson, director Adolescent Substance Abuse Program (CSTAR) at Burrell Behavioral Health.
Gibson says "Molly" has been around for years, but "it's made a resurgence," thanks to popular music and the idea that it's safe to take.
However, Gibson says that couldn't be further from the truth. People who buy the drug don't know how it's been made.
"So that's where the dangers get into it, especially when you are buying it, you don't know really what you're buying when you take it."
But it's easy to find and the popularity is growing. More and more kids are visiting drug treatment centers like Burrell, saying "Molly" is their drug of choice.
One problem, Gibson says, is that young people don't believe it's addictive.
"They may have used other things and once they start using Molly, people will tell you it's not addictive, but they don't want to quit using it, so that says a lot right there."
And they don't consider the long-term dangers.
"If I keep taking it over a prolonged period of time it can really cause some physical effects, which is why the kids are ending up in the hospital," adds Gibson.
Since the drug is most popular among teens, Gibson says parents need to be on alert if their kids want to invite "Molly" to their next party.
Some things parents can look out for with their kids are major personality changes and lack of sleep.
