DSST Substance Abuse Practice Exam

The correct response identifies impaired coordination and slurred speech as common physical effects of alcohol use. When alcohol is consumed, it acts as a central nervous system depressant, which slows down brain function and disrupts communication between neurons. This neurological impact directly affects motor skills, leading to unsteady movements and a lack of coordination. Individuals under the influence of alcohol often struggle with balance and muscle control, which can be observed in activities such as walking or performing any task that requires fine motor skills.

Additionally, slurred speech is another hallmark of alcohol consumption. Alcohol affects the muscles involved in speech production, leading to slurred words and difficulty articulating thoughts clearly. As a result, these two physical effects are widely recognized symptoms of alcohol intoxication and are important indicators for assessing an individual's level of impairment due to alcohol use.
