MILWAUKEE (WITI) -- Are YOU familiar with "Molly?" There's a good chance your kids know about it! It's a powerful drug, popular in the club and festival scene. What your kids may not know is what's actually in the bag.
In clubs and at festivals across the country, huge crowds gather every summer.
They are moved by the music -- and for some, the beat is enhanced by a drug known as "Molly."
Two people agreed to walk with FOX6 News about their experience with Molly -- but asked that we protect their identity.
"As soon as I closed my eyes, I was like whoa! It affects all the five senses. You move your hand and there's like, a glow after it. You're kind of like...wow!" Molly user #1 told FOX6 News.
"It's a feeling that -- the way people describe it is euphoria. It makes light a lot brighter. The theory is that Molly is the pure MDMA in powder form," Molly user #2 told FOX6 News.
MDMA is better known as ecstasy.
It has long been popular in the club scene. Once available only in pill form, the drug arrived on dance floors as a powder with the new name.
"We used to call it cutting electricity out of the air. It felt like you could take a knife and just cut electricity out of the air -- and just like, look at it," Molly user #1 said.
"It kind of helps you connect and communicate with people," Molly user #2 said.
The Molly users that talked with FOX6 News say their first experiences were life-changing.
"Myself personally, coming to terms with my relationship with my father," Molly user #2 said.
Law enforcement officials say Molly is dangerous.
"You're playing Russian roulette with what you`re putting into your body. You have no idea what that substance is going to be," James Bohn, the Assistant Special Agent in Charge with the U.S. Drug Enforcement Agency.
Bohn says what many users don't realize is that they don't really know what they're taking.
The DEA says while users think they're getting the pure form of MDMA, Molly is often laced with other chemicals and drugs.
Many bags contain no ecstasy at all!
"It`s all clandestinely manufactured. It`s all clandestinely sold, so it`s kind of a buyer beware, in an illegal market," Bohn said.
The DEA says bad batches can have deadly consequences.
In June of 2013, one person died and 125 were hospitalized after ingesting Molly at the Central Washington State Music Festival.
In August of 2013, three people overdosed and one died at a bar in Boston.
Days later, a concert was shut down after two died and four overdosed at a festival in New York City.
"You lose the ability to regulate your body temperature -- and people basically were burning from the inside out," Bohn said.
"It's something that can't be taken lightly," Molly user #1 said.
These admitted drug users say there is more risk now, since more people are trying Molly.
"I think it is scary, and I think when you talk about it as a drug -- and when you talk about it now, really you can`t call it a single drug right? It`s really whatever is in the bag," Molly user #2 said.
These users also say taking the drug doesn't always guarantee a good time.
"It can produce a euphoric feeling, but that is right at the beginning. What`s going to happen the other eight hours? That`s where it causes a lot of damage," Molly user #1 said.
The drug's side effect of depression has it's own name: Suicide Tuesday.
"It's something that can't be abused. It will just mess with all of your senses and emotions," Molly user #1 said.
"You're risking your life every time," Bohn said.
Knowing the risks, the users FOX6 News spoke with don't agree on whether they'll use again.
Molly user #2 tells us he will "absolutely" take the drug in the future -- but Molly user #1 says he "doesn't think he will."
The street price for Molly can be as low as $20.
