Actress Sharon Stone recently disclosed experiencing severe withdrawal symptoms after discontinuing marijuana use, a personal account that aligns with growing expert concerns about the potency of contemporary cannabis products.

Stone recounted in an interview with Variety that upon quitting, she became "pretty sick for a month" and sought help from her neurologist. The physician reportedly informed her, "Sharon, I’ve had people dying in the emergency room from marijuana," attributing Stone's experience to the increased strength of today's marijuana.

Experts corroborate that modern cannabis products are significantly more potent than those available decades ago. Dr. Chris Tuell, clinical director of addiction services at the Lindner Center in Cincinnati, noted that THC levels, the primary psychoactive compound in cannabis, have risen from approximately 3-5% in the 1980s to as high as 30% in flower products and over 90% in concentrates. This surge in potency is linked to a higher risk of dependence, cannabis use disorder (CUD), and more severe withdrawal symptoms, according to the National Institute on Drug Abuse.

While cannabis withdrawal is generally not considered life-threatening on its own, severe symptoms, pre-existing medical conditions, or interactions with other substances can complicate recovery. Common withdrawal symptoms can include insomnia, irritability, anxiety, appetite loss, sweating, and headaches, with acute physical symptoms typically resolving within a month, though mood and sleep disturbances can persist longer.

New research also casts doubt on some purported cannabis benefits, with studies indicating increased mental health risks, particularly for adolescents. Conditions such as PTSD, anxiety, depression, ADHD, and bipolar disorder have been linked to higher rates of use among young people. Since the early 2000s, marijuana usage among Americans aged 12 and older has increased substantially, leading to heightened concerns about addiction and associated health issues.

Addiction specialists emphasize that cannabis can be addictive, especially with high THC levels, and that addiction may not always be obvious. The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), outlines criteria for dependency, including using larger amounts over longer periods than intended, unsuccessful attempts to cut down, failing to meet responsibilities due to use, and continued use despite relationship problems.

For individuals experiencing significant withdrawal or those with co-occurring mental health conditions or substance use disorders, medical guidance may be beneficial. Experts advise that underlying mental health issues often co-exist with CUD, and addressing these can aid in reducing problematic marijuana use. Addiction experts also strongly suggest a gradual reduction in THC intake to mitigate severe rebound symptoms.
