Drug addiction is characterized by compulsive substance use that leads to an impairment in judgment, paranoia, aggressiveness, and more. A person who abuses a drug will eventually need more and more of it to produce a similar effect. This can increase the risk of an overdose and also exacerbates the adverse effects of drug consumption.
Drug addiction can be treated, if the disorder is identified at an early stage and treatment is sought from a trained mental health professional. Treatment includes psychotherapy, group therapy, medication management, and more. Detoxification and abstinence is the key to long-term recovery from the disorder that sustains.
