Methylone's behaviour profile is fairly similar to MDMA, which is as likely to kill you as riding a horse. It's not addictive, like Meth, Heroin, Nicotine or Cocaine. It is a scheduled substance though, and so it is illegal to import, possess or sell. )
Interesting. I was under the impression the effects are similar to MDMA, but that Methylone has far more harmful side effects. Even so, these research chemicals are still relatively untested compared to stuff like MDMA, Meth, Nicotine, etc.
I'm still blown away that moron mentioned a 250% profit margin on Himalayan salt in his blog. He's totally fucked.
