This isn't legal or controlled, but if you spend some time attending music festivals, you can come across just about and drug you would imagine (speaking about the US). LSD and mushrooms are popular at these shows. Speaking from experience, I would that if you have a personality that can handle finding drugs, then this would be less risky than buying from an online source.
