In 2023, Minnesota legalized adult recreational cannabis use. Cannabis includes the dried flowers, leaves, stems, and seeds of the cannabis plant and contains two main chemicals: tetrahydrocannabinol (THC), which causes impairment and a “high,” and cannabidiol (CBD), which does not cause a high but can still affect the user.
In the 1960s and ‘70s marijuana was widely considered an “all-natural” substance, and the psychoactive potency reflected that perception. At that time the average level of THC was usually around just 1%. Now, vapes and joints routinely push 30% THC, while dispensary shelves are stocked with concentrates—some boasting 90% to 95% THC—in the form of waxes, edibles, and more (Prince, M. A., & Conner, B. T., Behaviour Research and Therapy, Vol. 115, 2019)” (https://www.apa.org/monitor/2025/06/marijuana-potency-policy-risk)
Research shows that long-term, daily, or near-daily cannabis use can lead to memory damage lasting a week or longer after use, hallucinations and paranoia (temporary psychosis), and an increased risk of developing psychotic disorders such as schizophrenia. Youth are especially vulnerable because the brain continues developing until about age 25. Cannabis use at a young age may disrupt brain development related to attention, memory, and learning, increase the risk of addiction, lead to poorer school performance, and raise the likelihood of suicidal thoughts. Although more research is needed, current evidence indicates cannabis can alter behavior and interfere with normal brain development.
Regular cannabis use may also negatively affect physical health. Studies suggest daily use can increase the risk of heart failure, stroke, and heart attack. People with existing cardiovascular conditions should consult a healthcare provider before using cannabis and consider possible drug interactions. Smoking or vaping cannabis can damage the lungs, worsen respiratory symptoms, and increase episodes of chronic bronchitis. Individuals with asthma or chronic obstructive pulmonary disease (COPD) may experience greater harm from cannabis smoke.
To reduce risks, people should not drive after using cannabis, as driving under the influence is dangerous and illegal. Cannabis should not be used during pregnancy or when pregnancy is possible. Products should be stored securely, out of sight and reach of children, and kept in child-resistant containers.
Consuming too much THC can cause poisoning or serious injury, and effects vary based on product strength, strain, and THC analogues. Excessive use may lead to cannabinoid hyperemesis syndrome, sometimes called “scromiting,” characterized by severe, persistent vomiting, screaming, and dehydration, with only hot showers providing temporary relief. This condition can cause dangerous complications and requires medical attention. If someone, especially a child, consumes too much THC or has a severe reaction, immediate medical help should be sought or Poison Control contacted at 1-800-222-1222.
