Acute effects of high‑potency cannabis flower and cannabis concentrates on everyday life memory and decision making
2021
This is the first study to examine acute effects of cannabis on prospective memory, temporal order memory, resistance to framing and sunk cost biases, under/overconfidence and consistency in risk perception. Despite the use of high-potency products, we failed to detect any significant effects on any of these outcomes. It is possible that this reflects a true absence of effects of cannabis on these aspects of cognition.
Indeed, the null findings on tests of non-normative decision making are consistent with the conclusions of some previous literature which has demonstrated minimal or mixed acute effects of cannabis on decision making. The availability of more potent cannabis products is not a new phenomenon.
In fact, higher potency products, like hashish, have always been available to consumers. Typically, when consumers encounter higher potency products, they consume lesser quantities of them. This self-regulatory process is known as self-titration.
