Shrooms are awesome. I've eaten lots and definitely recomend them.

Coke can be fun too but I really don't advocate doing it. Some people can do a bit here, a bit there, and that's it. Other's really end up having a serious problem with it. When I was doing it, it was always a "special occasion" type of thing. Not a regular thing like weed, shrooms, or acid. If you're "surrouned with people doing it and offerin it to me " I would recommend staying away. Just too much tempation to do it on a regular basis.
