Substance addiction is a serious mental illness characterized by a dependence on a psychoactive substance such as alcohol or illegal drugs. The person with this disorder has difficulty controlling their substance use and continues to use it despite negative consequences on their health, social life, and work.

Symptoms

Symptoms of substance addiction can vary depending on the substance consumed and the severity of the dependence. Here are some signs that may indicate substance addiction:

• Strong desire or need to consume the substance
• Increased need for the substance to achieve the same effect
• Unsuccessful efforts to reduce or stop consumption
• Relational, professional, or legal problems due to consumption
• Mood disorders such as anxiety or depression in the absence of the substance

Treatment

Treatment for substance addiction may include a combination of therapy, medication, and social support. Cognitive-behavioral therapy (CBT) and group therapy can help the person understand and change the thoughts and behaviors underlying their addiction. Medications may be used to help reduce withdrawal symptoms and prevent relapses. Social support may include assistance from a support group such as Alcoholics Anonymous or Narcotics Anonymous.

Advice 

If you have a loved one with substance addiction, it is important to show them your support and love, but also to set clear boundaries and protect yourself. Here are some tips:

• Encourage the person to seek professional help
• Offer your support during treatment, but do not try to do it in their place
