The drug cocaine comes from the leaves of the Coca shrub. The white powder that sniffed most of the nose is chemically extracted. The effect occurs after a short time and can last up to 60 minutes. The result is an elevated mood, the suppression of sexual inhibitions and it can lead to increased performance. Again, there is the danger of prolonged consumption in dependence.
The alkaloid cocaine is recovered from the leaves of the coca shrub by a chemical extraction process and converted into a powdery substance (cocaine hydrochloride). The cultivation area of the coca plant is mainly South America. Until the beginning of the 20th century, cocaine was used in medicine as a local anesthetic or for headache and fatigue. Later it was banned because of the high addictive potential. Nonetheless, cocaine has become one of the most popular scene drugs worldwide. Consumers are mostly members of higher social classes. In case of cold, the usual form of consumption, the effect occurs after two to three minutes and lasts for up to one hour. It can also be sprayed or smoked. Smoking or spraying causes a much faster, stronger but shorter lasting euphoric "kick". Cocaine increases efficiency, self-esteem and sexual desire. Hunger feelings are suppressed. It acts in the central nervous system and enhances the secretion of the body's neurotransmitters dopamine, norepinephrine and serotonin. At the same time, their reuptake into the nerve cell is prevented. This causes an extreme stimulation of the nervous system, which is characterized by an increased pulse rate, talkativeness, increased breathing and enlargement of the pupils. After this euphoria subsides, it often leads to depressive moods that can lead to the re-use of the drug. This is where the source of danger of the drug lies - namely the psychological dependence.
