Drug Dependency – What is it?

Drug abuse is the overuse or misuse of drugs for non-medical purposes. These can be illicit drugs such as speed, ice or prescription drugs such as Valium or common anti depressants such as Xanax, Codeine, Oxycodone (Endone), Dexamphetamine, etc.

Types Of Drug Dependency

There are three main kinds of drugs, each of which causes different physical and mental reactions:


Heroin, cannabis, alcohol and other depressants slow your breathing and heart rate down and in small quantities can make you feel happy and relaxed.

But while they can provide a short-term sense of pleasure, they also bring on feelings of anxiety or depression in some people and regular long-term use can negatively affect your mood, making it harder to cope with everyday life.


Speed, ice, cocaine, ecstasy and other stimulants increase your heart rate, body temperature and blood pressure and can give you a temporary ‘buzz’ which makes you feel more confident, motivated and energetic.

However, they can also have a number of side effects including stomach cramps, headaches, dizziness and feelings of anxiety, paranoia and aggression.


LSD, ketamine, magic mushrooms and other hallucinogens cause you to hear and see things that aren’t really there.

As a result of hallucinogens, many experience unpleasant changes to their reality as a result,which can cause anxiety, depression, paranoia and psychosis in those susceptible to mental health problems.

The effect each of these types of drugs has on the user depends on their BMI and the amount and regularity with which the drug is being consumed, but all three have the potential to be both physically and mentally addictive.
