Sharon Stone’s account of becoming ill after quitting cannabis has prompted discussion of the risks associated with higher-potency modern marijuana products.

– Stone said she was unwell for about a month and consulted a neurologist after stopping cannabis.
– An addiction specialist said cannabis products now may contain up to 30% THC, while concentrates can exceed 90%, compared with roughly 3–5% in the 1980s.
– Higher THC levels are associated with increased risks of dependence, cannabis use disorder, psychosis in some people and more severe withdrawal symptoms.
– Withdrawal may begin within 24–48 hours and can include insomnia, irritability, anxiety, appetite loss, sweating, headaches and stomach upset; it is generally not considered life-threatening.
– The article advises people with significant health conditions, mental-health concerns or simultaneous withdrawal from other substances to seek medical guidance.
