Sharon Stone's terrifying weed withdrawal sparks warning about today's potent marijuana

Hollywood icon Sharon Stone recently opened up about a health scare after quitting marijuana, revealing her symptoms were so intense that she turned to a neurologist.

During an interview with Variety, the actress said her decision to quit was driven by a desire for a drug-free life.

"And because I think they put so much stuff in it now — they really do — when I stopped smoking pot, I also got sick," she said.

CANNABIS COMPOUNDS COULD REVERSE DISEASE AFFECTING ONE-THIRD OF ADULTS

"I got pretty sick for a month. I went to my neurologist, and he said, ‘Sharon, I’ve had people dying in the emergency room from marijuana.'"

Stone attributed her ordeal to the potency of modern weed, saying, "It’s not like you’re pulling it out of the ground anymore ... It’s not like when we were kids."

Experts note that cannabis withdrawal itself is generally not considered life-threatening, although severe symptoms, underlying medical conditions or interactions with other substances can complicate recovery.

FLYING WITH CANNABIS? TSA'S NEW GUIDANCE COMES WITH A MAJOR HEALTH WARNING

Dr. Chris Tuell, clinical director of addiction services at the Lindner Center in Cincinnati, confirmed that today's cannabis products are vastly different from the strains of decades past.

THC levels in marijuana have surged from about 3% to 5% in the 1980s to as high as 30% in today's cannabis products, while concentrates can exceed 90% THC, he told Fox News Digital.

Higher THC concentrations have been linked to greater risks of dependence, cannabis use disorder (CUD), psychosis in some users and more severe withdrawal symptoms, according to the National Institute on Drug Abuse.

As today's cannabis products become increasingly potent, experts say there are several risks and warning signs that daily users should know before deciding whether to continue — or quit — using marijuana.

According to Cleveland Clinic, CUD occurs when marijuana takes over the brain's reward pathways, amplifying compulsive behavior.

"I do believe cannabis is addicting, especially with the high levels of THC," Tuell told Fox News Digital.

The American Psychiatric Association’s DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition) outlines the following diagnostic criteria signaling that casual use may have crossed into dependency.

Quitting heavy, long-term cannabis use can trigger withdrawal symptoms within 24 to 48 hours, Cleveland Clinic notes.

Users frequently experience severe insomnia, intense irritability, anxiety, appetite loss, sweating, headaches and stomach upset. While acute physical symptoms typically resolve within a month, mood swings and sleep issues can linger much longer, according to Tuell.

While cannabis withdrawal alone rarely requires hospitalization, Cleveland Clinic notes that people with significant medical or mental health conditions — or those stopping cannabis while also withdrawing from alcohol, opioids or certain other medications — may benefit from medical supervision.

Mental health conditions often occur alongside cannabis use disorder, and treating those underlying issues may help reduce problematic marijuana use, according to the National Institute on Drug Abuse and the Cleveland Clinic.

"I strongly believe that CUD and mental health issues co-exist, and that mental health counseling can address the issues driving the addictive behaviors," Tuell said.
