Heavy cannabis use linked to urinary tract problems in young adults

This large-scale database study examined the relationship between Cannabis Use Disorder (CUD) and lower urinary tract symptoms (LUTS) in over 168,000 young adults aged 18-34. Researchers used propensity score matching to compare health outcomes between individuals with CUD and matched controls over a 5-year period. The findings reveal a significant association: individuals with CUD had 69% higher risk in males and 81% higher risk in females of developing new-onset LUTS compared to their peers without CUD.

The study identified increased risks for multiple specific urinary conditions among CUD patients, including dysuria (painful urination), pelvic/perineal pain, and urinary tract infections in both men and women. Notably, the research found no significant association between CUD and overactive bladder (OAB), suggesting that cannabis-related urinary issues may involve specific mechanisms rather than affecting all lower urinary tract functions equally. These findings were statistically significant across all measured groups.

The research highlights an important but understudied health consequence of regular cannabis use in young adults. While the study establishes a clear association between CUD and LUTS, the authors emphasize that further research is needed to understand the specific mechanisms by which cannabinoids affect lower urinary tract function. This work contributes to growing evidence that heavy cannabis use may carry risks beyond psychiatric or respiratory concerns, particularly relevant for young people with developing habits.
