1. Amphetamine, is a synthetic drug which is a phenylisopropylamine. Chemists often use the term "amphetamine class" to describe chemicals that are structurally similar (and often similar in effect as well) to amphetamine--namely, chemicals with an ethyl backbone, terminal phenyl and amine groups, and a methyl group adjacent to the phenyl.

10. Amanita muscaria "Fly Agaric" Amanita muscaria is a color variant of Amanita muscaria. Amanita muscaria can be white, yellow, red, orange or even brown. The book Alice in Wonderland was written by Lewis Carroll after he had experimented with Amanita muscaria and the changes in size and time perception described in Alice in Wonderland are characteristic effects of the mushroom intoxication.

11. Amanita muscaria Siberian tribesmen valued Amanita muscaria for its effects and would even trade a prized reindeer for one or two dried specimens. When they urinated on the ground an hour after eating the mushrooms, the reindeer would come for the salt in the yellow snow and become intoxicated, clueing poorer tribesmen to capture the urine for their own intoxication. The common name "Fly Agaric" refers to the fact that in the Middle Ages Europeans learned that the mushroom crushed in a saucer of milk would attract flies that would become stupefied and drown. In some parts of the world, Amanita muscaria is still used as an insecticide.

13. Effects Amanita muscaria, is one of the seIt induces muscle spasms, dizziness (and vomiting, if too many mushrooms have been eaten), then a deep sleep, full of fantastic dreams, lasting about 2 hours. On waking, the subject usually experiences a 'good trip': a feeling of elation that persists for several hours. People often become hyperactive, making compulsive and uncoordinated movements, perhaps talking non-stop, and having altered perceptions of reality. Occasionally the experience is a 'downer.' Clearly, Amanita muscaria contains a substance that specifically affects the central nervous system.

18. Effects As with other psychedelics such as LSD, the experience, or "trip", is strongly dependent upon set and setting. A negative environment could induce a bad trip, whereas a comfortable and familiar environment would allow for a pleasant experience. Many users find it preferable to ingest the mushrooms with friends, people with whom they are familiar, or people who are also 'tripping'.psychedelicsLSDset and settingbad trip
