Smoking shrooms, is not a very good idea. It is not Poisonous or lethal. But the active ingredients are changed by smoking them. Therefore the experience is different. Still very enjoyable though. The problem with smoking shrooms is that it causes flashbacks.
Do shrooms get old/stale? I have some leftovers (less than an 1/4) that are about 6-8 months old. Are they still good to eat? They were good the first time I had them.
I've tried smoking, I don't know how many herbs and most of them that give an effect orally, give an effect when smoked. Mostly different(milder) and shorter.
