Cannabis popularity continues to rise, with approximately 15% of Americans identified as current users and more than 22% having used it in the past year. As people cut out alcohol during the Dry January trend, dispensaries have reported a surge in marijuana sales, with some industry insiders and media outlets dubbing the phenomenon “High January.” While cannabis has been promoted for potential medical benefits including pain relief, reduced anxiety, and improved sleep, health experts warn that today’s cannabis products are far more potent than in previous decades and carry significant health risks.
Mental Health and Brain Function Effects
Mental health professionals caution that while some users initially feel calmer, cannabis often increases anxiety, panic symptoms, emotional blunting, and in some cases paranoia or psychosis—particularly risky for people with underlying anxiety, depression, or trauma histories. A recent study from Truveta, a health data company analyzing de-identified electronic health records from U.S. health systems, found that emergency department visits for cannabis-induced mental health disorders rose nearly 50% between 2019 and 2020 and remained elevated through 2023. Regular marijuana use affects attention span, memory, and motivation; clinically, users describe feeling “stuck”—less emotionally responsive, less driven, and less engaged with life. Early and frequent use is linked to long-term changes in cognition and emotional regulation, and increased risk of severe substance use disorders later in life. THC suppresses rapid eye movement (REM) sleep, disrupting normal sleep architecture and interfering with memory consolidation and emotional regulation. Chronic marijuana use is associated with decreased deep sleep and higher rates of sleep fragmentation.
Cardiovascular and Addiction Risks
Recent studies suggest marijuana users face elevated risk of heart attack and stroke. A meta-analysis of more than 400 million patients found a significant increase in major cardiovascular events, including 29% higher likelihood of heart attack, 20% higher risk of stroke, and twice the chances of cardiovascular death, with highest danger for those using cannabis at least weekly. Approximately 30% of people who use cannabis develop cannabis use disorder, characterized by an inability to stop using despite significant negative effects. Symptoms include cravings, unsuccessful quit attempts, tolerance, and withdrawal. Stopping can lead to irritability, insomnia, anxiety, and mood changes. In December, President Trump issued an executive order calling for marijuana to be reclassified from Schedule I to Schedule III under the Controlled Substances Act, citing a 2023 FDA review that found scientific support for medical use in treating pain, anorexia, and nausea/vomiting.
