Tolerance refers to a physiological state in which a person requires larger doses of a substance to achieve the same effects that they once experienced at lower doses. When it comes to hallucinogens, repeated use can lead to diminished effects over time. This phenomenon occurs because the brain and body adjust to the presence of the drug, resulting in a reduced response to its acute effects.

In the case of hallucinogens, individuals may find that the vivid experiences, alterations in perception, and emotional responses they initially encountered become less intense as they continue to use the drug regularly. Therefore, tolerance can effectively diminish the acute effects, meaning that the user may need to increase their dosage to regain the previous level of experience. This is a critical aspect for addiction counselors to understand, as it impacts treatment strategies and the risk of increased substance use.

It's essential to note that while hallucinogens may not lead to physical dependence in the same way substances like opioids or alcohol might, the development of tolerance can still influence usage patterns and the experiences associated with the drug.
