Drug addiction is a chronic brain disease which causes mental and physical harm to the user. People start to abuse drugs for a variety of reasons, such as peer pressure and stress, and many become addicted to different types of drugs.
As drug addiction becomes established there are changes in the brain. These neurochemical changes affect the person’s self-control and decision making processes. There is a strong impulse to continue taking drugs despite the harm that drug use is causing.
Addiction to drugs can take hold quickly, and the user requires increasing amounts or stronger substances to achieve the desired effect. Drug craving and drug withdrawal keeps the user 'hooked' and those suffering from addiction often resort to crime to fund the habit.
When people are addicted to drugs they are usually in denial about their addiction and unwilling to get help for their drug addiction.They do not see that they are addicted and often blame those around them for the problems that have arisen from their drug abuse. Sadly, drug addiction not only affects the user, but also their family and friends.
