Tolerance Building: Not Just Physical, Not Just Opioids

Direct Answer

Across public conversations, 'tolerance building' is often narrowly understood as a purely physical process related solely to opioids. This is a common misconception; tolerance building encompasses a broader range of physiological and psychological adaptations to various substances and behaviors, not just physical dependence on specific drugs. Understanding this broader scope helps clarify the complex ways individuals respond to repeated exposure and how these responses influence perception and behavior.

It is important to note that acknowledging the complexity of tolerance building does not diminish the significance of physical dependence where it occurs. Instead, it expands the understanding of how diverse forms of tolerance manifest across different substances and behavioral patterns. This broader perspective moves beyond a singular, drug-specific model.

Common Misunderstandings

One common misconception is that tolerance only applies to illicit drugs or prescription opioids. The correction is that tolerance can develop to a wide range of substances, including alcohol, caffeine, nicotine, benzodiazepines, and even certain behavioral patterns.

Another misunderstanding is that tolerance always implies addiction. The correction is that while tolerance is a component of physical dependence, which can be part of addiction, it does not, by itself, equate to addiction. An individual can develop tolerance to a medication without meeting criteria for a substance use disorder.

Many believe tolerance building is solely a physical phenomenon. The correction is that psychological and behavioral tolerance also occur, where the body and mind adapt to the effects of a substance or behavior over time, requiring more to achieve the desired psychological or subjective effect.

In Practice

This means that a client may describe needing more alcohol to feel relaxed or more cannabis to achieve a certain effect, using language like 'my tolerance is really high now.' It also means a client on long-term benzodiazepine therapy might report needing increasing doses to manage anxiety, attributing this solely to a 'weakness' rather than a physiological adaptation. Or, family members might dismiss a loved one's increasing use of a non-opioid substance because 'it's not an opioid, so tolerance isn't a big deal.'

What This Does NOT Mean

This does not mean that all tolerance building is indicative of a substance use disorder. This does not mean that physical dependence on opioids is any less significant. This does not include a judgment on the 'good' or 'bad' nature of tolerance, but rather an observation of its diverse manifestations.
