Título: Are arthritic patients using cannabis? A descriptive study

Autora: Jessica Carnivali-García

Resumen: Background & Objectives: The medical use of cannabis is quickly becoming a largely relevant topic of study. Pain management, along with sleep disorders and anxiety have been consistently reported by medical cannabis users within the literature. Similarly, chronic pain remains an important component of burden for patients with arthritis. Given that some arthritic patients are using cannabis for medical purposes while its therapeutic effects are still being studied it is important to understand and monitor this population. The objective of this study was to describe a sample of arthritic patients and their use of cannabis. Methods: The weighted sample was comprised of 13658 arthritic patients residing in states with medical cannabis programs in 2017, the dataset analyzed was the 2017 Behavioral Risk Factor Surveillance System from the CDC. Descriptive analysis was performed for cannabis use, arthritis burden and socio-economic characteristics. Results: The sample was composed mainly of retired white older women with some college education. Only a small percentage (7.3%) of arthritic patients were currently using cannabis. Within current users, 65.3% were medical users, 23.1% were non-medical, 11.6% combined reasons; and 69.1% consumed cannabis by smoking. Within patients burdened with arthritis there was a higher percent of medical use. Conclusion: A small percent of burdened arthritic patients appear to be using cannabis mainly for medical purposes. Further research is warranted to explore the associations of cannabis use and arthritis burden.

Título: The Use of Cannabis for Medical Purposes in Puerto Rico: Prevalence and Correlates Compared across Seven Other States with Medical Cannabis Programs

Autora: Jessica Carnivali-García

Resumen: The medical use of cannabis has come a long way in the past 20 years. Yet, little is known about the extent to which it is used solely for medical purposes, or how medical users compare with recreational users. This study aimed to estimate the prevalence of medical-only cannabis use for six US states and Puerto Rico and compare medical-only users with nonmedical users, and mixed medical and non-medical users. In total, 4,994 respondents from the 2018 BRFSS comprised the analytic sample. Prevalence and bivariable associations of cannabis use between the user groups and the dependent measures were examined, and multinomial logistic regression was used to ascertain the adjusted association. Overall, 28.3% of respondents reported medical-only use, 38.0% non-medical use, and 33.7% mixed medical and non-medical use. Medical-only users compared to non-medical users were more likely to use it daily (OR= 3.25, p <.001), showed higher odds of vaporization (OR= 3.41, p <001); were less likely to report daily drinking (OR=.311, p <.001), more likely to report being former smokers (OR= 2.05, p <.001), and current smokers (OR= 1.56, p <.001), showed higher odds of spending more days without good physical or mental health (p <.001), and higher odds of sleeping poorly (OR= 2.70, <.001) or excessively (OR= 1.65, p .001) compared to non-medical users. Lastly, medical users were more likely to report: heart attack OR= 3.24, coronary heart disease OR= 2.90, stroke OR= 4.34, asthma OR= 1.76, any other type of cancer OR= 3.43, COPD OR= 3.11, arthritis OR= 3.99, depressive disorder OR= 3.02, kidney disease OR= 2.30, and diabetes OR= 3.28; p <.001, than non-medical users. The findings suggest that there is a small group of medical only cannabis users with worse overall health profile compared to those that use it non-medically or both medical and non-medically. As the overall perspective of cannabis use continues to change, health professionals should be aware of changes in prevalence and reasons for use at population level to better guide patients and medical cannabis policies.
