Drug Addictions

Are all drugs addictive?
It depends on what we mean by addiction – see What do we mean by drug addictions ? People can become psychologically dependent on any drug – or anything else for that matter. This means that the person using drugs feels they cannot cope or face the world unless they are under the influence of drugs. This form of dependency has more to do with the people using the drug rather than about the particular drug they are taking.

Physically Dependant

In contrast people can only become physically dependent on certain drugs. Physical dependency results from the repeated, heavy use of drugs like heroin, tranquillisers and alcohol. Heavy and continual use of these drugs can change the body chemistry so that if someone does not get a repeat dose they suffer physical withdrawal symptoms - the shakes, flu like effects. They have to keep taking the drug just to stop themselves from feeling ill.

Drug Abuse

Continual use of drugs like cannabis, ecstasy and LSD does not result in physical dependency, even though people may become psychologically dependent. With other drugs – and particularly stimulant drugs such as cocaine, crack, amphetamine and the nicotine in cigarettes – there is debate over the extent that physical dependence or drug addictions can occur.
