2C-B is a phenellthylamine first synthesized by
Alexander Shulgin.
I was never in pain any time I took it (around 10 times), it used to be legal and cheap, now it's a Schedule II substance. The experience is like a mix of acid and ecstasy but still unique. The trip usually lasts between 5-8 hours in my experience. Other drugs in the 2C family are more fun in my experience, namely 2C-I which felt like a mix of acid and ecstasy as well but with better defined visuals and a more euphoric trip. And I wouldn't snort it, put it in a gelcap or something, you can even sprinkle it on your tongue if you like but it tastes oddly sweet and thoroughly disgusting.
Your mileage may vary.
