Summary
"Participants felt significantly drowsier and more tired after THC, whatever the driving condition. Driving stability was significantly impaired after THC, both in simulated and real driving conditions."
Summary
"Acute ∆9-THC administration produced transient anxiety and psychotomimetic symptoms, the latter being greater in non-users compared to users [...] In non-users, the more severe the ∆9-THC-induced psychotomimetic symptoms and cognitive impairments, the more pronounced was the neurophysiological alteration. Previous modest cannabis use blunts the acute behavioral and neurophysiological effects of ∆9-THC, which are more marked in people who have never used cannabis."
Summary
"The 25-mg dose produced significant drug effects [...], increased incidence of adverse effects, and pronounced impairment of cognitive and psychomotor ability [...] Several subjective drug effects and observed cognitive and psychomotor impairments persisted for up to 6 hours on average."
