Why we checked itAyotte asserts that today's marijuana is significantly more potent than in the past and is specifically causing addiction in youth — a specific factual claim about THC potency trends and addiction rates that can be checked against clinical data.
What we foundThe claim is well-supported: modern marijuana is demonstrably far more potent than in previous generations, and higher-potency cannabis is independently linked to greater addiction risk, especially among young people.
