A cross-sectional study of the relationship between frequency of cannabis use and psychiatric symptoms among people seeking mental health and addiction services in Nova Scotia (2019-21)
Abstract – Background: Cannabis use may be a modifiable risk factor for mental health problems; however, the role of cannabis use frequency in population seeking mental health and addiction services remains unclear. This study aimed to: 1) compare the prevalence and functional impact of psychiatric symptoms among frequent, infrequent, and non-users of cannabis; and 2) evaluate the associations between cannabis use frequency and functional impact of psychiatric symptoms in help-seeking individuals.
Results: Frequent and infrequent cannabis users had a higher prevalence of psychiatric symptoms in each domain than non-users, while no significant differences were found between frequent and infrequent users. Frequent cannabis use was associated with greater functional impact of psychiatric symptoms in each domain compared to non-users, while infrequent use was only associated with greater functional impact of externalizing behaviors.
Conclusion: Frequent cannabis use is associated with increased prevalence and functional impact of psychiatric symptoms among adults seeking mental health services. (Source: https://pubmed.ncbi.nlm.nih.gov/38518571/ )

This trend is exacerbated by kid-friendly edible packaging and product design. Products are often sold in colorful packaging and are made to look like and taste like candies, cookies, and other snacks. Many toddlers eat these THC products not knowing that they are in fact marijuana. Additionally, many users fail to properly store marijuana products, leaving them accessible to kids.

To examine the association between co-use of commercial tobacco product (hereafter referred to as tobacco) and cannabis with educational outcomes among high school students.
Results: Current co-use of tobacco and cannabis was more than double the use of only tobacco (3.7% vs 1.7%) and similar to only cannabis (3.7%). Almost 18% of students reported absenteeism. Compared with students who used neither substance, students with current co-use had greater odds of absenteeism (aOR 1.41, 95% CI 1.33-1.49) and lower grades (β = −0.87, 95% CI −0.92 to −0.82). Compared with students using tobacco alone, students with co-use also had a significant elevated odds of absenteeism (aOR 1.19, 95% CI 1.10-1.29) and lower grades (β = −0.39, 95% CI −0.46 to −0.32). Similar results were found for students who ever used tobacco and cannabis.
Conclusions: California youth who co-use tobacco and cannabis were most likely to have absenteeism and lower grades. Comprehensive efforts to prevent or reduce youth substance use may improve educational outcomes.

50+ peer-reviewed studies from all 50 States in the US (325 million pop.) and 27 EU countries (511million pop.) published 2021-23 have verified what had been known from in vitro and in vivo studies for decades, that cannabis is genotoxic, carcinogenic and teratogenic. These studies now verify that cannabis is causal in:
- 33 cancer types as against 14 for tobacco (Cannabidiol CBD] is the most carcinogenic cannabinoid [12 cancers])
- 70% of pediatric cancer types
- 89 of 95 birth defects tracked by the European Medicines Agency
