Sharon Stone’s cannabis withdrawal highlights risks of today’s high-THC pot

Sharon Stone says quitting marijuana made her so sick she consulted a neurologist, highlighting how today’s high-THC cannabis (flower up to ~30% and higher in concentrates) can drive dependence and severe withdrawal. Experts warn cannabis use disorder involves changes in the brain’s reward system, with withdrawal symptoms like insomnia, irritability, anxiety, appetite loss, sweating and headaches; most symptoms resolve within weeks, but mood and sleep issues can linger. Medical guidance and a slow taper are advised, especially for those with medical or mental health conditions or concurrent substance use, and underlying mental health issues should be addressed to reduce risk.
