What is tolerance building?
Direct Answer
Tolerance building occurs when an individual requires increasing amounts of a substance or activity to achieve the original desired effect. This means the body or mind has adapted to previous levels of exposure. It does not necessarily indicate addiction or substance use disorder on its own.
Common Misunderstandings
["One common misunderstanding is that tolerance building automatically equates to addiction. Tolerance is one factor among several that are considered in evaluating substance use. Addiction involves compulsive use despite negative consequences.","Another misunderstanding is that a lack of tolerance building means there is no concern. Some substances or activities may not show significant tolerance development but can still lead to harmful use patterns."]
In Practice
When tolerance builds, the initial quantity or intensity might no longer produce the expected result. For example, a person might previously feel a specific effect from a certain dose. With tolerance, that same dose produces a diminished effect. This often leads to increased intake to attempt to regain the original effect. The body adapts to the presence of the substance or the frequency of the activity. This adaptation means the system functions differently than it did before. The initial response is no longer achieved with the same input.
What This Does NOT Mean
["This does not mean that tolerance building is always problematic. Certain medications, when taken as prescribed, can lead to tolerance building without indicating misuse or dependence. It is a physiological response, not inherently a sign of disorder.","This does not include situations where a substance's effect is consistent over time. Some substances do not produce significant tolerance. It also does not include instances where an individual is simply seeking a stronger effect from new substances or activities.","This does not guarantee the presence of withdrawal symptoms if use stops. While tolerance often precedes withdrawal, withdrawal is a distinct phenomenon. Not all tolerance building results in physical withdrawal discomfort."]
