What is the primary risk associated with the use of controlled drugs?

The primary risk associated with the use of controlled drugs is dependency and abuse. Controlled substances are often regulated due to their potential to be addictive. When individuals use these drugs, especially without medical supervision, they may become reliant on them to function or feel normal, leading to a cycle of increased use and potential withdrawal symptoms when not using the drug. This dependency can have serious physical, psychological, and social consequences, including health issues, impaired judgment, and strained relationships.

The other options do not accurately reflect the main risks of using controlled substances. While some may claim enhancements in cognitive or physical performance, these effects are often temporary and can mask the negative consequences of drug use. Similarly, while some individuals may experience short-term social interactions when under the influence, these interactions can lead to problematic behavior and further dependency. Thus, the focus on dependency and abuse captures the most significant and concerning risk associated with controlled drugs.
