USE & ABUSE OF DRUGS

DONE BY: SHAIBAN IBRAHIM 9S-1

WHAT IS A DRUG ?

a substance used in the prevention, cure, or alleviation of disease

or pain or as an aid in some diagnostic procedures.

TYPES OF DRUGS

Most psychoactive drugs fall into the categories of : Stimulants Depressants Opiates Hallucinogens

STIMULANTS

Stimulants act on the central nervous system and are associated with feelings of extreme well-being, increased mental and motor activity. Examples include cocaine, crack cocaine, amphetamines (speed) and ecstasy (which is also a hallucinogen).

DEPRESSANTS

Depressants are chemicals that slow down the central nervous system and suppress brain activity causing relief from anxiety. The most common depressants are alcohol and cannabis. Others include barbiturates and benzodiazepines (e.g. vallium, temazepam). 

OPIATES

Opiate drugs provide pain relief, euphoria, sedation and in increasing doses induce coma.

Examples include: heroin, morphine, opium, methadone, dipapanone and pethidine.

HALLUCINOGENS

Hallucinogens cause changes in a person's perception of reality. These include cannabis, LSD, ecstasy and psilocybin (magic mushrooms).

DRUG ABUSE

An excessive or improper use of drugs, especially through self-administration for nonmedical purposes.

REACTIONAL DRUGS:

Recreational drugs use is the use of psychoactive substances to have fun, for the experience, or to enhance an already positive experience. National laws prohibit the use of many different recreational drugs and medicinal drugs that have the potential for recreational use are heavily regulated. Many other recreational drugs on the other hand are legal, widely culturally accepted, and at the most have an age restriction on using and/or purchasing them.

HEROIN

Heroin is an opioid drug that is synthesized from morphine, a naturally occurring substance that is extracted from the seed of the Asian poppy plant. Heroin usually appears as a white or brown powder or as a black sticky substance, known as “black tar heroin.”

The scientific name for heroin is diacetylmorphine.

EFFECTS OF HEROIN

• After an intravenous injection of heroin, users report feeling a surge of euphoria (a “rush”) accompanied by a dry mouth, hot flushes, heaviness of the hands and feet, and clouded mental functioning. Following this initial euphoria, the user alternates between a wakeful and drowsy state.

• Heroin has a rapid effect, beginning with euphoria and feelings of peace and contentment. It makes the user indifferent to hunger and sexual urges, and masks all inhibitions, fears and remorse - shielding the user from his or her immediate environment, both internal and external. This makes heroin one of the most addictive of all the illicit drugs.
