The use of certain chemicals to produce pleasurable effects on the brain is referred to as drug misuse or substance abuse. Over 190 million people use drugs worldwide, and the problem has been growing alarmingly, particularly among young adults under 30. In addition to the long-term harm that drug usage does to the body, drug users who use needles run the danger of getting HIV and hepatitis B and C infections.

Causes of drug use

Drugs of abuse are usually psychoactive drugs that are used by people for various different reasons which may include:

  1. Particularly among young individuals and students in schools, curiosity and peer pressure
  2. Prescription medicines that were first prescribed to treat pain may have been used recreationally and developed an addiction.
  3. Chemicals may be utilized in religious ceremonies or practices.
  4. Recreational objectives
  5. For the purpose of finding inspiration


Drug categories

Drugs of abuse fall into three groups and these include:

  1. Depressants: These impair the functions of the brain and include substances like heroin and sleeping medications (barbiturates).
  2. Stimulants: These stimulate the brain, resulting in heightened alertness and bursts of activity. Along with behavioral changes including agitation and poor judgement, further symptoms include a quick heartbeat, dilated pupils, elevated blood pressure, nausea or vomiting, and dilated pupils. With the use of cocaine and amphetamines, delusional psychosis may arise in extreme cases.
  3. Hallucinogens: These produce hallucinations and a dissociative state that feels "out of this world." Hallucinogens can lead to delusions, paranoia, sadness, and even impaired sensory experience. Ecstasy, mescaline, and LSD are some instances.
