I don't think the dose for amanita muscaria is 1-5 grams. Smoking the extract would be damn cool. But, your lungs would throw a shit fit. Amanita's make for just a 'stoned' feeling when you smoke em. I bet extract might be even moreso, or less needed for effects. Most people take between like 15 and 30 grams dried. So I don't know what extract number the amanita extract is, but if you just want to eat it, it should probably be 15x+.

Anyway, if you do decide to skip em, get some HB Woodrose. They rock large amounts of rockingness, and are legal. Just don't get em from Iamshaman, their's are duds.
