Cannabis is becoming increasingly popular in 2026, with estimates indicating that around 15% of Americans currently use it and more than 22% have used it in the past year. With the trend of Dry January prompting many to cut back on alcohol, dispensaries are reporting a notable spike in marijuana sales, coining this phenomenon “High January.”
The potential medical benefits of cannabis—such as pain relief, reduced anxiety, and improved sleep—are often emphasized. However, experts caution about the associated health risks of its use.
Corey Gamberg, an expert in mental health and addiction, highlights a common misconception that marijuana is completely safe because it’s “natural.” He notes that today’s cannabis products are significantly more potent than those from previous decades, leading to various mental, emotional, and physical issues observed in clinical practice.
Trent Carter, an addiction recovery specialist from New Mexico, has noticed that while marijuana has gained acceptance, he’s seen a rise in negative side effects among his patients. Many use it to address mental and physical health issues, only to develop new symptoms over time.
Impact on Mental Health
Gamberg warns of the adverse effects of marijuana on individuals with underlying conditions like anxiety or depression. Although some users may initially feel relaxed, he observes increases in anxiety, panic, emotional blunting, and even paranoia in certain cases. For vulnerable populations, cannabis might worsen rather than improve mental health.
Worryingly, recent studies have shown a nearly 50% rise in emergency visits for cannabis-related mental health issues between 2019 and 2020, a trend that seems set to continue.
Brain Function and Motivation
Gamberg notes that regular cannabis use can affect various aspects of brain function such as attention, memory, and motivation. Individuals often describe a sense of being “stuck,” feeling less emotionally responsive and lacking motivation.
Concerns are especially heightened for younger users, as early and frequent marijuana use can have long-term effects on cognition and emotional regulation, increasing the risk of severe substance use disorders later in life.
Impact on Heart Health
New research indicates that cannabis users may face higher risks of heart attacks and strokes, with a recent meta-analysis revealing a 29% increase in heart attack risk and a 20% rise in stroke risk among frequent users.
Sleep Disorders
Though marijuana is sometimes used as a sleep aid, experts caution that its use can disrupt normal sleep patterns. THC may inhibit REM sleep, which is essential for processes like memory consolidation and emotional regulation. Users may experience poorer sleep quality over time.
Cannabis Use Disorder
Nicole Short, a specialist in cannabis use disorders, points out a prevailing belief that cannabis is non-addictive. However, she asserts that dependency can develop, and stopping use can lead to withdrawal symptoms such as anxiety and irritability.
Regulatory Movement
In December 2025, an executive order reclassified marijuana, lowering its status from a Schedule I to a Schedule III drug, recognizing its medical uses and potential for misuse. This change is reflected in a 2023 FDA review that supported the medical application of marijuana for conditions like chronic pain and nausea.
Effects May Vary
It’s crucial to recognize that cannabis affects individuals differently, influenced by factors like dosage and usage patterns. While some people may experience positive effects with low doses, high doses can lead to adverse outcomes. Therefore, proper medical guidance is essential.
As discussions around cannabis continue, experts emphasize the importance of providing accurate information. There’s a need for clear communication about both the benefits and potential risks associated with cannabis use.
If anyone is facing negative health effects from cannabis, seeking professional medical advice is strongly recommended.
