Explanation:
1- Cocaine is an alkaloid that is often used as an intoxicant. Cocaine is extracted from leaves of the shrub plant Erythroxylon coca, which grows in South America, especially in Colombia, Bolivia and Peru. Colombia is responsible for the production of more than 75% of all cocaine.
In pure form, the effect of cocaine is considerably stronger than in the cocoa leaves. Medically, it was used for local anesthesia until synthetic cocaine was developed in the 1940s. Even today, cocaine can be used as a local anesthetic in special cases.
Cocaine can be used in a variety of ways to promote energy and a sense of well-being, while reducing the need for food and sleep. It provides rapid onset and powerful intoxication. The body reacts with higher blood pressure. How much depends on dose and administration. The cocaine intoxication is intense but short-lived, usually 15-60 minutes. The substance is highly addictive.
Even in small doses, the user is given a feeling of being very upstairs, but can also lead to bizarre and violent behavior. The user can become restless, excited and extremely anxious with panic. Chronic cocaine users can develop irritability, insomnia and suspicion, sometimes also hallucinations and persecution.
2- Caffeine is an alkaloid that acts as a psychoactive stimulant drug. It is found in various amounts in beans, leaves and fruits in over 60 different plants.
In humans, caffeine is a stimulant of the central nervous system that has the ability to temporarily counteract fatigue. The use of caffeinated beverages, such as coffee, tea, soft drinks and energy drinks, is widespread in all ages around the world. Caffeine is the world's most consumed psychoactive drug. Every year, 120,000 tonnes of caffeine are consumed globally.
3- Morphine is a drug used for pain relief, among other things. It is classified as an alkaloid opioid analgesic and a drug.
Morphine is one of the main constituents of opium and is the basis for the preparation of heroin, codeine and other opium derivatives (opioids) used as analgesics, cough suppressants and stopping agents. There is a risk, among other things, of breathing problems in overdose.
4- Heroin is an analgesic opioid officially known as diamorphine. It was first synthesized in 1874 by Charles Romley Alder Wright by adding two acetyl groups to a volcano of morphine, naturally found in the opium poppy. Heroin on its own is a non-active drug, but when put into the body, it is converted into morphine. Like other opioids, heroin is used both as an analgesic and as a recreational drug. Frequent use is associated with tolerance and physical dependence.
5- LSD is a semisynthetic psychedelic that causes the user to have an altered state of consciousness, which may include, for example, hallucinations. It does not cause physical dependence and the development of psychic dependence is rare. LSD is not known to cause brain damage and has very low dose-proportional toxicity. Anxiety and paranoia can be caused as psychological side effects.
6- Marijuana is an herbal substance and drug made from hemp plants. The intoxicating and medicinal effects of cannabis are based on herbal cannabinoids. It is most commonly used because of its psychoactive and physical effects, which include increased mood, euphoria, relaxation, increased appetite, and an emphasis on associations and sensory experiences.
