A Historical Tolerance Review Separated the Label High From Other Cannabis Effects

A 1976 review argued that reports of feeling high could reflect expectancy and labeling as well as pharmacology. Its discussion illustrates why subjective intoxication and adaptation on other endpoints should not be treated as interchangeable.

The source was an interpretive synthesis

The review discussed behavioral compensation, tissue adaptation and drug disposition across species and functions. It did not present one new experiment establishing a universal mechanism. Its broad claims should therefore be read as historical interpretation of the evidence then available.

Expectancy could complicate apparent increased sensitivity

The author discussed placebo-related explanations for reported reverse tolerance in experienced smokers. A stronger reported high after repeated exposure does not necessarily establish a stronger receptor response. Conversely, a placebo contribution does not mean every reported effect is imaginary or pharmacologically absent.

Distinct endpoints can retain distinct histories

The source considered subjective labeling alongside residual tolerance on other effects. These can coexist because a report of high is not the same measure as physiological or behavioral performance. The review's older statements about dependence prevalence are not presented here as current clinical conclusions.

Applying the distinction

When comparing subjective ratings across repeated exposures, ask whether expectations, instructions and comparator conditions were held constant. Then ask whether the conclusion concerns subjective experience or another measured function. A history of reported increased sensitivity cannot, by itself, settle whether a physiological response became more or less tolerant.

What the finding means

The enduring methodological point is to ask what was measured, what participants expected and what comparison controlled those expectations. This historical review does not supply an individual impairment test or establish that subjective ratings can be ignored. It supports interpreting them in context.
