UPDATE: New research from the University of Bath in the UK urgently proposes safe consumption limits for cannabis, aiming to reduce the risk of cannabis use disorder (CUD). This groundbreaking study, published in the journal Addiction, defines thresholds similar to alcohol units, allowing users to better monitor their THC intake.
The study recommends that adults should not exceed 8 THC units per week, equating to approximately 40 mg of THC or one-third of a gram of herbal cannabis. Exceeding this limit significantly increases the risk of developing CUD, which affects an estimated 22% of regular cannabis users, causing serious impairment in daily life.
Researchers Dr. Rachel Lees Thorne and Professor Tom Freeman revealed that the risk of more severe CUD rises sharply above 13 THC units weekly. Their analysis, based on the CannTeen study, tracked 150 cannabis users over a year, revealing alarming statistics: 80% of users below the threshold did not report CUD symptoms, while 70% of those above did.
Dr. Lees Thorne emphasized the study’s goal: “The only truly safe level of cannabis use is no use. However, for those who don’t want to stop or can’t, our guidelines aim to lower harm.” The research encourages users to consider THC units alongside consumption frequency, promoting informed choices.
With cannabis legalization expanding globally, this research is particularly relevant. The findings have attracted attention in countries like Canada, where officials are advocating for clearer THC labeling on products. Dr. Robert Gabrys from the Canadian Center on Substance Use and Addiction acknowledged the importance of this research, stating it assists in understanding health risks associated with cannabis use.
As cannabis products continue to diversify, the need for standard THC units becomes increasingly crucial. The Bath team plans to expand this research internationally, developing tools to help users track their consumption based on local contexts.
Public health bodies are now urged to adopt these THC unit guidelines, enhancing consumer knowledge and safety. The implications for cannabis regulation are profound, as authorities strive to equip users with the information needed to make safer choices.
Stay tuned for further updates on this developing story as the research gains traction worldwide, aiming to reshape how cannabis use is approached and understood.
