What is a key indicator of substance abuse disorder?

The need for drugs to function normally is a key indicator of substance use disorder because it signifies a physical or psychological dependence on the substance. When an individual reaches a point where they cannot manage daily activities or cope with stress without the use of drugs, it suggests that their body and mind have adapted to the presence of the substance. This dependency often leads to increased tolerance, where the person requires more of the drug to achieve the same effect, and withdrawal symptoms when not using, further reinforcing the cycle of abuse.

Occasional social use of drugs does not reflect a disorder; rather, it might be seen as typical behavior for some individuals who use substances responsibly. Participating in drug education programs is usually a preventive measure rather than a manifestation of addiction, and minimizing drug intake over time can indicate a positive step towards recovery rather than a marker of disorder. Thus, the need for drugs to function normally clearly demonstrates the characteristic reliance associated with substance use disorder.
