Drug use and effects

Drug use can also be termed as drug abuse; it is the misuse of certain substances. Therefore, it can be described as intentional, improper use of a substance that may have excessive, dangerous or undesirable effect on an individual (Abadinsky, 2008, p. 4).
Drugs can be classified in two main categories: legal and illegal. Legal drugs are those that regulations and laws control their availability, price and quality such as tobacco. On the other hand, illegal drugs are those that are not regulated by regulations and laws such as heroin. These drugs are usually toxic, and prolonged use of them leads to death (Abadinsky, 2008, p. 224)

Drugs have an effect on the nervous system. They can be classified as stimulants, depressants and hallucinogens. Each has different effects on the nervous system. For example, large consumption of stimulants can lead to over stimulations and cause panic, anxiety, seizures, stomach cramps, headache and aggression. However, the hallucinogen type of drugs affects people's perception; those who use them are likely to hear or see things that do not exist; they tend to see things distorted. The effects of hallucinogen are unique for each person; this makes it difficult to identify them. Some of the effects are loss of appetite, talking or laughing, increased activity, psychological and emotional excitement (Abadinsky, 2008, p.187).

Depressants, the other type of drugs, do not always make someone feel miserable; taken in small quantities, they make one feel relaxed and inhibited. Depressants also affect user’s co-ordination and concentration thus making him slow to react; taken in large quantities, they cause vomiting, unconsciousness or even death (Woods, 1979, p. 56).
In conclusion, taking drugs without a specialist’s instructions is always harmful to someone’s health; therefore, drug should be regulated by use of regulations and law.
