- •Regular use lowers IQ; risk rises with heavier consumption.

Summary
The video warns that cannabis can damage memory and cognition even when users are not feeling high. It stresses that regular consumption lowers IQ and that the effect intensifies with heavier use, making it a concern for anyone who uses marijuana frequently.
Research cited shows that adolescent exposure—especially before age 16—leads to structural changes in white‑matter and raises the likelihood of psychosis. The presenter notes that memory deficits persist off‑dose and that long‑term cognitive decline is linked to cumulative exposure.
Clinicians advise patients to mitigate risks by selecting products with a higher CBD‑to‑THC ratio, avoiding smoked or vaped forms, and opting for tinctures or edibles. They also stress never to drive after use, even at low doses, and acknowledge that many patients rely on cannabis for chronic nausea despite the hazards.
The message underscores the need for broader public awareness, particularly among families with teenagers, as well as more research on older adults, who now represent the fastest‑growing segment of cannabis users.
