A comprehensive analysis of 80 scientific studies has identified a window of impairment of between three and 10 hours caused by moderate to high doses of the intoxicating component of cannabis, tetrahydrocannabinol (THC).

The study found the exact duration of impairment depends on the dose of THC, whether the THC is inhaled or taken orally, whether the cannabis user is regular or occasional and the demands of the task being undertaken while intoxicated.

While the intoxicating ingredient in marijuana, THC, can be detected for weeks after consumption, researchers found people remained impaired for between three and 10 hours after consuming moderate to high doses of cannabis. The Lambert Initiative for Cannabinoid Therapeutics was launched at Sydney University after Barry and Joy Lambert made a $33.7 million donation for research into the therapeutic use of medicinal cannabis.
