Acute Effects of THC on Time Perception in Frequent and Infrequent Cannabis Users
Psychopharmacology November 24, 2012 R. A. Sewell, Ashley Schnakenberg, Jacqueline Elander et al.
Intravenous THC, at doses from 0.015 to 0.05 mg/kg, produces time overestimation and underproduction in seconds-range tasks, indicating an increased internal clock speed. This effect is not dose related and is blunted in frequent cannabis smokers, who show no differences in time perception compared to infrequent or nonsmokers. Chronic cannabis use does not alter baseline time perception.
