What cannabis risk means
Acute effects can include impaired attention, memory, coordination, judgment, anxiety, and increased heart rate. Risk varies with THC exposure, age, frequency, route, other substances, and health conditions.
Cannabis findings depend on the product, dose, route of administration, population, and outcome measured. A result about one cannabinoid or formulation should not be generalized to every cannabis product.
How strong is the evidence?
We weigh systematic reviews and well-controlled human studies above observational reports, case series, animal studies, and laboratory experiments. Each can answer useful questions, but they do not support the same degree of certainty.
Long-term outcomes are harder to isolate because exposure patterns and confounding factors differ. Association does not always establish causation, but uncertainty is not evidence of safety.
