CLAIM DATABASE
Each record separates the claim, grade, confidence, rationale, source, review date, and correction history.
THC can affect reaction time, coordination, perception, and judgment. Risk depends on dose, timing, individual response, and co-use of alcohol or other substances.
Smoke from cannabis contains many of the same toxins and irritants as tobacco smoke. Evidence does not support calling inhaled smoke harmless.
Cannabinoids may help some treatment-related symptoms, but that is not evidence that cannabis cures cancer. Laboratory findings do not establish a human cancer cure.
A purified CBD medicine is FDA-approved for seizures associated with specific conditions. That does not validate every CBD product, dose, or epilepsy claim.
Some people develop cannabis use disorder. Estimates vary by definition, population, frequency, potency, and age of initiation, so a single universal percentage can mislead.
Research associates early, frequent use with cognitive concerns, but “every user” and a fixed permanent effect overstate what observational evidence can establish.
