What might increased tolerance indicate in relation to substance use?

Increased tolerance is a significant indicator in the context of substance use, as it typically suggests that an individual requires larger quantities of a substance to achieve the same effects that they once experienced with smaller amounts. This phenomenon occurs because the brain and body adapt to the presence of the substance over time.

When someone develops increased tolerance, it often signals that their body is undergoing changes that may be associated with the development of substance use disorder. This includes physiological adaptations that can lead to a cycle of increased consumption as users seek to regain the initial effects they experienced, potentially escalating their substance use and contributing to harmful patterns.

Understanding tolerance as a marker for substance use disorder is critical because it can guide interventions and help identify individuals who may be at risk, enabling them to receive appropriate support and resources. Recognizing the implications of increased tolerance allows healthcare providers and individuals to address substance use issues proactively, rather than waiting for more severe consequences to emerge.
