Outcomes
Primary Outcome Measures
Number of Self-administered Puffs of Smoked Cannabis Containing Active THC Concentrations Compared to Placebo Under Controlled Laboratory Conditions
The reinforcing effects of cannabis were determined using a modified progressive ratio procedure in which subjects made 8 choices between puffs of each available cannabis dose and money (US$0.50). The numbered of self-administered puffs of smoked cannabis are measured for each cannabis concentration (0 and 5.9% THC) during active (300 and 450 mg) and placebo (0 mg and 0 mg) pregabalin maintenance.

5. Study Description
Brief Summary
Cannabis is the most commonly used illicit drug in the United States, and its use is associated with rates of development of abuse and dependence, treatment admission and relapse that are comparable to other illicit drugs. Currently there is no effective pharmacological treatment for cannabis-use disorders. The purpose of the present study is to evaluate the ability of pregabalin to reduce cannabis use thereby evaluating its effectiveness as a medication for cannabis-use disorders.
