Top 8 Drug Categories


Drug Categories

Drugs come in various forms, and can be taken numerous ways. Some are legal and others are not. Drug abuse and misuse can cause numerous health problems, and in serious cases death can occur. Treatment for drug abuse is often sought to aid in recovery.


These drugs speed up the body’s nervous system and create a feeling of energy. They are also called “uppers” because of their ability to make you feel very awake. Stimulants have the opposite effect of depressants. When the effects of a stimulant wear off, the user is typically left with feelings of sickness and a loss of energy. Constant use of such drugs can have very negative effects on the user. In order to prevent extreme negative side effects of these drugs and the impact they have on life, drug treatment centers are often recommended.

Types of drugs include:

  • Cocaine
  • Methamphetamines
  • Amphetamines

Inhalants are sniffed or huffed and give the user immediate results. Unfortunately, these immediate results can also result in sudden mental damage.

Other effects include liver, lung and kidney problems, affected sense of smell, difficulty walking and confusion.

Types of drugs include:

  • Glues

  • Marijuana


Depressants slow down activity in the central nervous system of your body. These drugs are also called “downers” because they slow the body down and seem to give feelings of relaxation. Depressants are available as prescription drugs to relieve stress and anger, although drowsiness is often a side effect. The “relaxation” felt from these drugs is not a healthy feeling for the body to experience, to stop abuse of this drug, drug treatment is suggested.

    Kaye, Cannabis is said to be a hallucinogen because Marijuana produces hallucinations at times when taken. Marijuana is a drug that impacts your short term memory, making you forget at times what’s real and not. Any drug can be classified as a hallucinogen if it interferes with real perspective of life. Artists for instance find inspiration from the drug. This is one big reason it is said to be a hallucinogen drug.
