Chunk #7 — Do cannabinoids cause short-lived positive psychotic symptoms, negative symptoms and cognitive deficits in the general population? — Anecdotal evidence, case reports, and surveys
Some of the limitations of anecdotal accounts, case reports, and case series can be addressed by surveys of larger samples of individuals who have used cannabis. In large community samples, between 20 and 50% of individuals report acute transient psychotic symptoms, including paranoia, persecutory ideas, and hallucinations under the influence of cannabis [77, 114, 115, 185, 218].
