Is Building Tolerance a Myth or Real Concern?

Direct Answer

Tolerance is a physiological process. It involves a reduced response to a substance over time. This means the same amount of a substance produces a lesser effect. It also means increased amounts are required to achieve the original effect.

Tolerance does not necessarily mean addiction. Tolerance is a physical adaptation. Addiction involves compulsive use and negative consequences despite harm. However, tolerance can be a component of some substance use disorders.

Common Misunderstandings

["Some people wrongly believe tolerance is merely a mental desire for more. Tolerance is a measurable change in bodily responses. It is not solely psychological.","The idea that building tolerance guarantees addiction is incorrect. Tolerance can occur without addiction. Many factors influence the development of addiction.","Believing that tolerance only applies to illicit drugs is a misunderstanding. Tolerance can develop with prescribed medications and other substances. Alcohol and caffeine are common examples."]

In Practice

When tolerance develops, the body adapts to a substance's presence. Cells may become less sensitive to its effects. The body might also increase its efficiency in breaking down the substance.

This adaptation can lead to needing higher doses for the same outcome. For example, a person might need more of a pain medication for the same level of pain relief. Or, a person might need more caffeine to feel alert.

Developing tolerance does not determine an individual's intent or moral character. It reflects physiological changes within the body's systems.

What This Does NOT Mean

["This does not mean that tolerance is always a sign of problem use. Tolerance can be an expected outcome of consistent substance exposure. It varies by substance and individual.","This does not include the psychological desire for a substance, although those can co-occur. Tolerance is primarily a physical adaptation. Craving is a distinct phenomenon.","This does not imply a universal rate or amount for tolerance development. The speed and extent of tolerance vary greatly. It depends on the substance, dosage, frequency, and individual physiology."]
