4 drug classifications

4 Drug Classifications

  • Depressants

  • Stimulants

  • Hallucinogens

  • Anabolic Steroids

  • Exception of anabolic steroid, drugs in the classes are used to alter mood, thought, and feeling.


Drug dependency

Drug Dependency

  • Physical dependence:

    • Using the drug repeatedly makes the body need the drug to continue working

    • Will result in withdrawal when stop using

  • Psychological Dependence:

    • The users feels a “need” or “craves” the drug

    • They believe they cannot function without the drug

    • Can last longer than physical dependence


Drug terms

Drug Terms

  • Withdrawal- the body’s reaction to suddenly no longer getting that drug

    • Can be life threatening, must already have a dependency on the drug

  • Tolerance- the body’s reaction, or the effect of the drug, is lessened because of repeated use

    • It is reversible, can be both physical and psychological, depends on type of drug

  • Synthetic- made artificially, not naturally occurring


Depressants

Depressants

A psychoactive drug that slows brain and body reactions is called a depressant.

  • Depressants slow body functions by decreasing heart and breathing rates and lowering blood pressure.

    Examples:

    • Alcohol

    • Codeine

    • Oxycodone

    • Morphine

    • Marijuana

    • Heroin


Effects of marijuana

Effects of Marijuana

Marijuana is one of the most frequently abused psychoactive drugs.

Its main ingredient changes the way information reaches and is acted upon by the brain.

Side effects of marijuana use include

  • distorted perceptions

  • difficulties with thinking and problem solving

  • loss of motor coordination

  • increased heart rate

  • feelings of anxiety or paranoia


Stimulants

Stimulants

A stimulant is a drug that speeds up activities of the central nervous system.

Stimulants increase

  • heart rate

  • blood pressure

  • breathing rate

  • alertness

Physicians sometimes prescribe certain stimulants to treat sleep disorders and behavioral disorders.


Amphetamines

Amphetamines

Amphetamines (am FET uh meenz) are prescription drugs that are sometimes sold illegally as “speed” or “uppers.”

Amphetamine abuse produces feelings of well-being and high energy.

The effects wear off quickly and the abuser is often left feeling depressed.


Methamphetamine

Methamphetamine

A stimulant that is related to amphetamines, but is even more powerful, is methamphetamine.

Methamphetamine initially produces a rush, or “high.”

But, after the rush wears off, the user may become

  • confused

  • shaky

  • anxious

  • irritable

  • violent


Cocaine

Cocaine

Cocaine is a powerful but short-acting stimulant.

Cocaine is highly addictive.

When cocaine’s effects wear off, abusers often experience depression, which can be severe.

  • Crack is the strongest form of cocaine.

    Other example:

    caffeine, nicotine, speed


Hallucinogens

Hallucinogens

A hallucinogen(huh LOO sih nuh jun) is a drug that distorts perception, thought, and mood.

Hallucinogens overload the brain with sensory information, causing a distorted sense of reality.

Abusers

  • cannot tell what is real

  • may experience memory loss and personality changes

  • may be unable to perform normal activities

  • may lose track of time and their surroundings

LSD

The strongest known hallucinogen is lysergic acid diethylamide, or LSD.

LSD’s effects are unpredictable—it can either stimulate or depress the central nervous system.

Abusers experience hallucinations in which they may see colorful visions and mistakenly feel they have superhuman powers.

Mushrooms

Psilocybin is a chemical found in a certain type of mushroom.

The effects of psilocybin are much like those of LSD, but not as strong.

PCP

One of the most dangerous of all drugs is PCP, short for phencyclidine.

Because the drug eliminates the sensation of pain, abusers may unintentionally injure or even kill themselves.

Some PCP abusers develop signs of schizophrenia.


Club drugs inhalants and steroids

Club Drugs, Inhalants, and Steroids

Three classes of drugs that are of growing concern in recent years are club drugs, inhalants, and anabolic steroids.

The effects of club drugs and inhalants are extremely unpredictable and dangerous.

Abuse of steroids causes lifelong damage to the body and brain.


Club drugs

Club Drugs

Club drugs got their name from the fact that they first gained popularity at dance clubs and raves.

Their effects are different from person to person and very dangerous.

While under the effects of rohypnol (roh HYP nawl), a person may be hurt or raped and not even be able to recall the event later on.


Anabolic steroids

Anabolic Steroids

Anabolic steroids are synthetic drugs that are similar to the hormone testosterone.

Steroids are abused primarily by people who want bigger muscles.

Steroids can make a user’s personality very aggressive.

Some steroid users become severely depressed.


Inhalants

Inhalants

A breathable chemical vapor that produces mind-altering effects is called an inhalant (in HAYL unt).
