They explained that the predictor variable was self-reported cannabis use, stratified by frequency, ranging from none, 1-19 days per month, to 20-30 days per month. In addition, the primary outcome variable was adherence to recommended cancer screenings, while a multivariable-adjusted model evaluated predictors of adherence. A total of 229,711 patients were included in the analysis, corresponding to a weighted population of 46.9 individuals eligible for screening. According to the findings, high-frequency cannabis use, defined as 20-30 days per month, “was associated with lower adherence to breast cancer screenings (adjusted odds ratios \[aORs\], 0.70 \[95% CI, 0.54 to 0.91\]),” while moderate use, defined as 1-19 days per month, “showed no significant effect.” The findings also revealed that cannabis use at any frequency level correlated with “lower adherence to prostate cancer screenings (1-19 days: aOR, 0.76 \[95% CI, 0.58 to 0.98\]; 20-30 days: aOR, 0.60 \[95% CI, 0.44 to 0.82\]).”   Overall, high-frequency cannabis use correlated with lower adherence to recommended breast and prostate cancer screenings, and moderate-frequency use correlated with lower adherence to prostate cancer screenings alone. “Close monitoring of adherence to breast cancer screenings in women and prostate cancer screenings in men with frequent cannabis use might be beneficial,” the investigators concluded.     [by Cancer Nursing Today](https://www.cancernursingtoday.com/post/study-links-frequent-cannabis-use-to-lower-cancer-screening-rates)   [Medical Cannabis News](https://420intel.com/blog/tag/medical-cannabis-news) [Medical Marijuana News](https://420intel.com/blog/tag/medical-marijuana-news) ![Buzz](https://420intel.com/hs-fs/hubfs/Buzz-No%20Outline-2.png?width=200&height=200&name=Buzz-No%20Outline-2.png) #### [Buzz](https://420intel.com/blog/author/buzz) At 420 Intel, we cover cannabis legalization news throughout the world, offer reliable information for cannabis business owners, detail technological advances that impact the marijuana industry, cover marijuana rallies from across the globe, and everything in between. - - - [Medical Cannabis News](https://420intel.com/blog/tag/medical-cannabis-news) [![Cannabis users have elevated dopamine levels associated with psychosis](https://420intel.com/hs-fs/hubfs/AI-Generated%20Media/Images/The%20image%20depicts%20a%20brain%20scan%20displayed%20on%20a%20digital%20screen%20showcasing%20intricate%20patterns%20of%20bright%20colors%20illustrating%20neural%20activity%20Specifically%20areas%20of%20heightened%20intensity%20are%20highlighted%20in%20vibrant%20shades%20of%20red%20and%20yellow%20indicating%20elevate-1.jpeg?width=550&height=395&name=The%20image%20depicts%20a%20brain%20scan%20displayed%20on%20a%20digital%20screen%20showcasing%20intricate%20patterns%20of%20bright%20colors%20illustrating%20neural%20activity%20Specifically%20areas%20of%20heightened%20intensity%20are%20highlighted%20in%20vibrant%20shades%20of%20red%20and%20yellow%20indicating%20elevate-1.jpeg)](https://420intel.com/blog/cannabis-users-have-elevated-dopamine-levels-associated-with-psychosis) - [![Buzz](https://420intel.com/hs-fs/hubfs/Buzz-No%20Outline-2.png?width=80&height=80&name=Buzz-No%20Outline-2.png) Buzz](https://420intel.com/blog/author/buzz) - 10 April 2025 #### [Cannabis users have elevated dopamine levels associated with psychosis](https://420intel.com/blog/cannabis-users-have-elevated-dopamine-levels-associated-with-psychosis) A McGill University-led study found that cannabis users have elevated dopamine levels in a brain...
