And it get's worse. Because your not really tripping but rather fighting poisoning, it effectively cuts the connection to the better part of who you are. If it wasn't for alcohol, a lot of the trouble we see in society simply wouldn't exist.
Some would say the puke part is part of the cleansing, more spiritual than physical. Comparing shrooms to alcohol is very unfair. One is a spiritual plant, one is poison.
Pish. Once in a while, a drink is just the right elixer for a conversation or a mood change with a new friend. It doesn't deserve top billing, and the other drugs don't deserve to be so screwed, but it does have a deserved place in the human experience. Calling it mere 'poison' misses the mark for me.
