Yeah he did, and he's not the same. But there's a difference in safely taking moderate doses of drugs, and abusing them. In his case he was being stupid and mixed 5-meo with some mdma and fucked himself over. And he hasn't been the same since!! He does these weird movements that he's never even done before, and sometimes he acts like he can't even think. And keep in mind that 5-meo is a Maoi, and Extasy is a seritonin reputake inhibitor or something like that. When you start mixing those 2 kinds of drugs together, your bound to screw yourself up in the head, BIG TIME. So in his case, those 2 drugs he mixed really are the cause of his problems.
That's just like people who are heroin addicts. Yeah the drug is the cause of their problems because they can't stop. But someone who is moderatly doing it every once in a while shouldn't blame the drug for any of their problems because it's not an every day thing. Big difference there.
