What is substance use disorder?

Substance use disorder is the medical term used to describe a pattern of using a substance (drug) that causes significant problems or distress. This may be missing work or school, using the substance in dangerous situations, such as driving a car. It may lead to substance-related legal problems, or continued substance use that interferes with friendships, family relationships, or both. Substance use disorder, as a recognized medical brain disorder, refers to the use of illegal substances, such as marijuana, heroin, cocaine, or methamphetamine. Or the misuse of legal substances, such as alcohol, nicotine, or prescription medicines. Alcohol is the most common legal drug associated with substance use disorder.

Substance (drug) dependence

• Spending a lot of time to get, use, and recover from the effects of using drugs
• Withdrawal from social and recreational activities
• Continued use of the drug even though you are aware of the physical, psychological, and family or social problems that are caused by your ongoing drug use

What causes substance use disorder?

Cultural and societal factors determine what are acceptable or allowable forms of drug or alcohol use. Public laws determine what kind of drug use is legal or illegal. The question of what type of substance use can be considered normal or acceptable remains controversial. Substance use disorder is caused by multiple factors, including genetic vulnerability, environmental stressors, social pressures, individual personality characteristics, and psychiatric problems. But which of these factors has the biggest influence in any one person cannot be determined in all cases.  What is true is when the substance being used causes issues in your life, it is time to ask for help!
