The High Risks of High-THC Cannabis

While the landscape of cannabis legalization continues to evolve, recent scientific findings underscore the importance of understanding the potential downsides of high-THC marijuana. New research, highlighted in prominent sources like National Geographic, illuminates significant health risks, from cardiovascular complications to serious mental health impacts and addiction. Let's delve a little deeper so you can make informed choices for your well-being.
The Alarming Link Between High-THC Cannabis and Cardiovascular Disease
The latest studies provide compelling evidence that cannabis use, particularly products with high levels of THC, substantially increases the risk of serious cardiovascular events. One recent retrospective study, analyzing data from over 4.6 million individuals, found that cannabis users younger than 50 were more than six times as likely to experience a heart attack compared to non-users, even among those without prior cardiovascular comorbidities. Furthermore, a large meta-analysis of 12 previously published studies, encompassing over 75 million people, revealed a 50% increased risk of heart attack among active cannabis users. High THC Cannabis use causes inflammation of the Cardiovascular system. The risk of a heart attack can peak approximately one hour after marijuana consumption. Beyond heart attacks, cannabis use has also been linked to a fourfold increased risk of ischemic stroke and a twofold increased risk of heart failure. This is a critical public health concern, as cardiovascular disease remains the leading cause of death globally.
Beyond the Heart: Addiction, Hyperemesis, and Mental Health Concerns
The dangers of high-THC cannabis extend beyond cardiovascular health, touching upon issues of addiction, gastrointestinal distress, and severe mental health conditions. High-potency cannabis is increasingly recognized as habit-forming and addictive, with approximately 3 in 10 marijuana users developing cannabis use disorder. The potency of THC in street marijuana has significantly risen over the past two decades, with THC content increasing from 3.7% in 1993 to 12.6% in 2013 to upwards of 30-40% in NYC dispensaries in 2024/25. This rise in potency contributes to a higher risk of dependence and addiction.
Moreover, chronic heavy marijuana use can lead to Cannabinoid Hyperemesis Syndrome (CHS), characterized by recurrent severe nausea, intractable vomiting, and abdominal pain. First described in 2004, this side effect has seen a doubling in emergency room visits from 2017 to 2021, and it is estimated to affect as many as 2.75 million people in the U.S. annually. The only known long-term solution for CHS is complete abstinence from cannabis.
Mental health repercussions are another grave concern. Higher THC intake has been associated with an increased risk of psychotic symptoms, and a study published in The Lancet Psychiatry suggests that the risk of psychosis is three times higher in users of high-potency herbal cannabis than in non-users. Chronic heavy marijuana use, particularly beginning in adolescence, correlates with a higher risk of psychotic illness, earlier onset of schizophrenia, and persistent neuropsychological deficits. This is not to mention that high levels of THC can increase anxiety, panic attacks, and paranoia. These findings underscore the urgent need for greater public awareness regarding the full spectrum of risks associated with cannabis use.
Quitting Cannabis and Exploring CBD
Recognizing the harm of high-THC cannabis, many are looking to quit. Both smoking and edibles carry similar risks. Quitting "cold turkey" is an effective method, although a tapering plan can also be effective. Many of our clients at Spiral Herbal Remedies have found that slowly substituting our Organic, Plant-based Smoking Blend for high-THC cannabis is very effective, calming, and can help heal the lungs at the same time.
Withdrawal symptoms such as irritability, anxiety, mood swings, and sleep problems are common. For support in managing cravings and withdrawal, Spiral Herbal Remedies' Organic, THC-Free, CBD can help. The World Health Organization (WHO) has affirmed that CBD exhibits no effects indicative of abuse or dependence potential, and there is no evidence of public health problems associated with the use of pure CBD. Research suggests that CBD can help lower cravings for tobacco and heroin, and animal models indicate it may also lessen cravings for other addictive substances like cannabis. Beyond addiction management, CBD offers a myriad of other potential benefits, including reducing anxiety and depression, improving sleep, alleviating chronic pain and inflammation, and acting as a potent antioxidant.
When Marijuana was first being legalized, I enquired about the cost of a license. It's $1 Milllion in NYC. Only big corporations can afford that. I find it interesting that THC levels have skyrocketed with the opening of these dispensaries and that these severe health issues have now surfaced.
