Synthetic chemical which, when taken orally or, less commonly, in the lining of an eyelid or nostril, is the most potent hallucinogen known to the common public.
One of the cheapest drugs available, it is neither addictive nor physically dangerous. Taken by an intelligent, open-minded person, it can create fantastic revelations and experiences.
It is not a good party drug, and, in a hostile environment such as a party, it can lead to what is known as a 'bad trip', where the person under the influence of the substance in question has an experience which is totally frightening. Fear, depression and anger are accentuated to fill the entire body to a point where entire thought patterns are controlled by these emotions.
The same accentuation goes for happiness and relaxation, often leading to a state of artificial nirvana, the only difference being that the person is absolutely suggestible and can lose the ability to reason.
It is only when one becomes cocky and stupid that LSD causes bad effects.
