Drug addiction

Drug addiction is a condition which can be classified as abnormal. An addict is someone who is obsessed with a particular substance or substances which can be uncontrollable and compulsive which without having it can lead to withdrawal symptoms as the person’s body becomes dependent on this substance in order to function. This dependency on this substance continues and can become destructive. Drug addiction can be for the increase in demand for substance or even medication..

Drug addiction can start from a casual use of drugs, example when socialising which can become a habit where there is an increase of dosage which gradually leads to addiction. When a person is at the stage where they cannot survive without this dosage is when the person is known to become an addict as the person will have normal cravings for the substance

Addiction to drugs varies depending on the types of substance where the addiction has two measures: physical dependency and psychological dependency. Physical dependency means the body has become familiar with the drug and its absence will initiate withdrawal symptoms Psychological dependency happens when the mind relies on the effects of the drug and its absence produces cravings. An addict can possibly encounter both physical and psychological dependency. Drugs are often categorised as legal or illegal, hard or soft uppers or downers or addictive and non-addictive. However they can also be recognised based upon the effect they produce as stimulants, hallucinogens and depressants. Stimulants are drugs that increase the activity of the central nervous system and increase brain activity. Examples include alkyl nitrites, amphetamines, cocaine and crack, ecstasy,, , anabolic steroids and nicotine. Some of these give the feelings of greater confidence, energy and alertness. Depressants are drugs that reduce the activity of the central nervous system and slow down brain activity. Examples include heroin and tranquillisers, barbiturates, solvents and alcohol. Common affects of these drugs are impaired coordination, balance and judgement Hallucinogens alter perception of reality, changing the way users experience the world through their senses. Examples include cannabis, magic mushroom, LSD and ketamine. Often users will experience paranoia. Hallucinogens can also trigger psychotic reactions, including paranoia.

Drug users are often called 'junkies shooting up', and although there might be some truth in it most addicts do not measure up to this stereotype. Addiction sometimes start with a conscious decision to experiment with drugs, however scientific research has found that drugs interfere with normal functioning of the brain and have long-term effects on the brain’s activity. The extensive use of the drugs leads to drug addiction where the craving for the drugs becomes uncontrollable and that cannot be overcome without treatment. Addiction can affect anyone and both legal and illegal drugs can be addictive. Many view addicts as morally weak, yet addiction is a chronic, relapsing illness. An addict will experience withdrawal symptoms if their body is craving for the substance and they do not get it. Some common withdrawal symptoms are: • vomiting

• sweating
• shaking
• tremors
• insomnia.
