What does increased tolerance to a substance indicate?

Increased tolerance to a substance indicates that over time, an individual requires larger amounts of that substance to achieve the same effects that were once experienced with smaller doses. This phenomenon occurs because the body becomes accustomed to the presence of the substance, leading to physiological adjustments that diminish its effectiveness. As a result, an individual may find that what once provided relief, pleasure, or other desired effects is no longer sufficient, prompting them to consume larger quantities.

Understanding tolerance is crucial for counselors working with individuals facing substance use disorders, as it can highlight the level of addiction and necessitate changes in treatment strategies. While tolerance does not necessarily mean a person cannot stop using the substance or that they are emotionally better regulated, the increase in tolerance itself is a clear signal of diminishing effectiveness in relation to the substance's impact.
