HALLUCINOGENS OR HALLUCINOGENIC PLANTS Prepared By: Sujata Assistant Professor
Hallucinogens are natural and synthetic (synthesized) substances that, when ingested (taken into the body), significantly alter one’s state of consciousness. Hallucinogenic compounds often cause people to see (or think they see) random colours , patterns, events and objects that do not exist. Many types of substances are classified as hallucinogens, solely because of their capacity to produce such hallucinations. These substances are sometimes called ‘psychedelic’, or ‘mind-expanding’
A few hallucinogens have been used in medicine to treat certain disorders, but they must be given under controlled circumstances. The real danger of hallucinogens is not their toxicity (poison level), The actual causes of such hallucinations are chemical substances in the plants. These substances are true narcotics
MEDICAL USES OF HALLUCINOGENS: Hallucinogens have been studied for possible medical uses, including the treatment of some forms of mental illness, alcoholism and addiction to the drug opium. A synthetic form of the active chemical in marijuana, Tetra hydro cannabinol (THC) has been approved for prescription use by cancer patients, who suffer from severe nausea after receiving chemotherapy (treating cancer with drugs). THC is also used to reduce
eye pressure in treating severe cases of glaucoma. Phencyclidine (PCP) is occasionally used by veterinarians as an anesthetic and sedative for animals Some of the important plant hallucinogens are as follows : 1. Belladonna ( Atropa belladonna ) 2. Betel Nut ( Areca catechu ) 3. Donana ( Coryphantha macromeris ) 4. Henbane 5. Datura ( Datura species) 6. Marijhuana (Bhang)
