The acute effects of cannabis use: An escalating THC dose-finding pilot study in frequent cannabis users.
In this randomised, double-blind, dose-finding experimental study, frequent problematic cannabis users will attend 3 experimental sessions, in which they will be administered inhaled cannabis, with each session involving a different THC dose. The doses will be 10, 20, and 30mg of THC. The aim of the present preliminary study is to determine which dose of THC induces subclinical paranoid ideations and/or cognitive impairments in frequent cannabis users.
