Addiction is the inability to stop consuming a substance or engaging in a behavior despite the adverse health and social consequences. Doctors now diagnose addiction under the umbrella of substance use disorders.
While anyone can develop a substance use disorder, some personal and medical factors can increase the risk of dependence.
The most obvious risk factor is taking an illicit or mood-altering substance, but a complex web of risk factors can contribute to addiction. Many substances that form the basis of addiction are not chemically addictive. This means that other elements can lead to substance use disorders.
