DRUGS AND ALCOHOL ABUSE
The drugs, which are commonly abused are opioids, cannabinoids
and coca alkaloids. Majority of these are obtained from flowering plants. Some are obtained from fungi.

Opioids are the drugs, which bind to specific opioid receptors present in our central nervous system and gastrointestinal tract. Heroin
(Figure 8.7), commonly called smack is chemically diacetylmorphine which is a white, odourless, bitter crystalline compound. This is obtained by acetylation of morphine.

Cannabinoids are a group of chemicals, which interact with cannabinoid receptors present principally in the brain. Natural
cannabinoids are obtained from the inflorescences of the plant Cannabis sativa.
Coca alkaloid or cocaine is obtained from coca plant Erythroxylum coca, native to South America. It interferes with the transport of the neuro-transmitter dopamine. Cocaine, commonly called coke or crack is usually snorted.

Drugs like barbiturates, amphetamines, benzodiazepines, lysergic acid diethyl amides (LSD), and other similar drugs, that are ormally used as medicines to help patients cope with mental illnesses
