These drugs were legal at the time. I blame myself for my own actions(but it was almost a decade ago and I have moved on, which is why I'm comfortable being open about it), but blame is not always singular. The state is also partially to blame because they banned all the good drugs, leading to grey markets with dangerous, untested, experimental drugs.
As for my friend, I had nothing to do with what happened to him, I only met him after the fact.
Drugs are illegal for a good reason. What did you expect?
Your friend lost his mind, you narrowly escaped death and you blame the government for making this substance illegal? Correct?
