What is often a consequence of drug tolerance?

Increased drug dependency is a common consequence of drug tolerance because as a person develops tolerance to a substance, they often need to consume larger amounts to achieve the same effects. This escalation in usage can lead to a heightened physical and psychological dependency on the drug, as the individual may find it increasingly difficult to function without it. Over time, this can result in a cycle where the individual becomes more reliant on the substance not just for the intended effects but also to avoid withdrawal symptoms.

While other options present different scenarios related to drug use, they do not accurately reflect the dynamics associated with drug tolerance. For instance, complete cessation of drug use would be an uncommon response to tolerance; instead, individuals often increase their use. Improved coping with life problems suggests a beneficial outcome not usually linked to increased drug use or tolerance. Lastly, a decrease in substance cravings is contrary to what typically occurs; as tolerance develops and dependency increases, cravings often intensify, leading to further substance use.
