Claim summary · not a verbatim quotation
Marijuana, particularly edibles, can trigger schizophrenia in people who are predisposed to the condition.
The finding
What the evidence shows
The general point holds up. A King's College London study found <cite index="20-8">frequent cannabis use is linked to more psychosis, highest among daily users of high-potency cannabis</cite>. A UK Biobank study found <cite index="23-9">people genetically predisposed to schizophrenia may be especially vulnerable to psychotic experiences from cannabis</cite>. The "particularly edibles" part is weaker. The edible evidence is mostly case reports of acute, short-term psychosis from taking too much, not proof that edibles trigger schizophrenia more than smoking. A large study showing edible users develop schizophrenia at higher rates than smokers would back the claim.
