Adolescent cannabis users are neither more resilient nor more vulnerable than adult cannabis users to the acute psychotomimetic, verbal memory-impairing, or subjective effects of cannabis. In a randomized, double-blind, placebo-controlled crossover experiment with 24 adolescents (16-17 years old) and 24 adults (26-29 years old) who used cannabis 0.5-3 days per week, vaporized THC (8 mg for a 75 kg person) and THC plus CBD (24 mg) both significantly increased subjective drug effect, impaired verbal episodic memory, and increased psychotomimetic effects compared to placebo. There was no evidence that adolescents differed from adults in their responses, and CBD did not modulate the acute effects of THC.
