A new study from Boston University School of Medicine found that cannabis use among young adults in Georgia did not increase following recreational use legalization. However, they discovered an age of first use increased significantly and cannabis use was associated with other risk behaviors.
The study found that frequent users of high-potency cannabis had changes in genes related to mitochondrial and immune function, particularly the CAVIN1 gene. This effect was not explained by tobacco's impact on DNA methylation. The research provides valuable insights into how cannabis use may alter biological processes.

A significant increase in drug overdose rates was recorded in Colombia between 2010 and 2021, with a notable rise among young women. The study found that the pandemic contributed to higher levels of anxiety and mental health problems, leading to overuse of drugs, particularly tranquilizers/sedatives/antidepressants.
A cross-sectional study of commercially insured patients suggests that there may be meaningful heterogeneous associations between cannabis policy and state-level outcomes, as well as between cannabis policy and drug class, with implications for patient substance use and mental health outcomes.
A recent study by the Center for BrainHealth found that long-term cannabis use is associated with poorer sleep quality, which in turn affects memory performance. The research, published in The American Journal of Drug and Alcohol Abuse, involved 141 adults with cannabis use disorder and 87 non-users.

The study suggests caution when it comes to cannabis use during pregnancy, highlighting the need for continued research into long-term effects.
A recent analysis found that cannabis use and cannabis use disorder are associated with increased workplace absenteeism. The study, published in the American Journal of Preventive Medicine, showed that even infrequent cannabis use can lead to more workdays missed due to illness or injury.
A large multicenter study found that adults with cannabis dependence are 3.5 to 5 times more likely to develop head and neck cancer than non-users. The researchers suggest that the primary reason for this increased risk is the damaging effect of cannabis smoke, which may be worse than tobacco smoke.
A cohort study found an association between cannabis-related disorder and the development of head and neck cancer. The study highlights the need for further research on the mechanism of this association and dose response to support evidence of cannabis use as a risk factor.
A new study found that Cannabigerol (CBG) significantly reduced feelings of anxiety at 20, 45 and 60 minutes after ingestion, with stress ratings also decreasing. CBG's effect on memory was unexpectedly positive, enhancing the ability to recall lists of words.
A significant increase in cannabis use among adults with diabetes has been found, with a 33.7% rise in prevalence between 2021 and 2022. Cannabis use may be driven by perceived therapeutic benefits and increased access to products after legalization.
A cohort study found that prenatal cannabis use was associated with several negative maternal health outcomes during pregnancy. The study emphasizes the need for further research on how different aspects of prenatal cannabis use may impact these associations.
