Peyote: source for mescaline production
Hallucinogen is a drug of natural or chemical origin that causes changes in perception (most commonly visual), in the ability to think and in the mood of the person who eats it.
The best known hallucinogens
The most common hallucinogens are LSD (Lysergic Acid Diethylamide) and mescaline (a cactus known as Peyote).
Mechanism of action in the body
There is no common mechanism of action for hallutionogens, although many of them are structurally similar to central nervous system neurotransmitters (eg, serotonin and catecholamines).
Human health effects
Hallucinogens have considerable effects on the health of humans and vary according to the type used, amount and organism of the person. LSD, for example, has several negative effects, the most common being paranoia, mental confusion, anxiety, panic, concentration problems and even psychosis.
