Behavioral signs of drug use may include which of the following?

The behavioral signs of drug use often manifest in various ways, particularly through emotional and psychological changes. Nervousness, paranoia, or evasion are common indicators of substance abuse. Individuals under the influence of drugs may experience heightened anxiety, feel unusually suspicious, or attempt to avoid conversations and situations where their drug use might be discovered. These behaviors are often a direct result of the psychological effects of the substances being used.

In contrast, increased confidence and focus, engagement in social activities, or improved work performance may not reliably indicate drug use. Such behaviors could also stem from other factors unrelated to substance use, making them less indicative of drug use. Thus, the signs of nervousness, paranoia, or evasion provide a clearer link to potential drug-related issues among individuals, making them the appropriate choice for identifying behavioral signs of drug use.
