Drug addiction, also termed substance use disorder, is a disease that adversely impacts a person’s brain and behaviour. The affected individual is unable to control the use of the drug. The addict continues to use the substance despite the harm caused by its usage.

Drug addiction can begin with experimental use of recreational activity in social situations. For some people, the drug use becomes more frequent. For others, particularly in the case of opioids, drug addiction starts with exposure to prescribed medications.

The risk of addiction and how fast you become addicted varies by drug. Some drugs, such as opioid painkillers, cause addiction more quickly than others.

As time passes, the person will need larger doses of the drug to get high and feel good. As the drug consumption increases, the individual may find that it is increasingly difficult to go without the drug. Attempts to stop drug usage may trigger intense cravings and physical illness (withdrawal symptoms).
