A recent study conducted by researchers at the University of California San Diego has shed light on the potential risks associated with in-home cannabis smoking and its impact on children. The study, published in the journal JAMA Network Open, found that in-home cannabis smoking significantly increased the likelihood of children being exposed to cannabis smoke.
Smoking is a common method of cannabis consumption and is known to produce harmful emissions that can be detrimental to those who are exposed. With cannabis often being smoked indoors, non-smokers, especially children, are at risk of being exposed to these harmful substances.
Lead researcher John Bellettiere, Ph.D., M.P.H., emphasized the concerns surrounding cannabis smoke, stating that it contains carcinogens, respiratory irritants, and other harmful chemicals. The study revealed that households where in-home cannabis smoking was reported had five times higher odds of children having detectable levels of cannabis in their urine.
The research team analyzed data from households in San Diego County to investigate the correlation between in-home cannabis smoking and the presence of cannabis biomarkers in children’s urine. The results showed that 69% of households with reported in-home cannabis smoking had children with detectable cannabis biomarkers, compared to 24% in households without in-home cannabis smoking.
It is important to note that the study’s participants were predominantly from low-income households enrolled in the Women, Infants, and Children Supplemental Nutrition Program, which may limit the generalizability of the findings to the broader U.S. population.
Osika Tripathi, Ph.D., M.P.H., a recent graduate of the UC San Diego—San Diego State University Joint Doctoral Program in Public Health, stressed the importance of reducing in-home cannabis smoking to protect children from exposure to toxic and carcinogenic chemicals found in cannabis smoke. Tripathi suggested adopting strategies from tobacco control efforts, such as comprehensive smoke-free laws and policies, to safeguard children’s health.
Moving forward, Bellettiere highlighted the need to further investigate the long-term health risks associated with second-hand cannabis smoke exposure. The study underscores the importance of addressing in-home cannabis smoking practices to mitigate the potential health risks posed to children.
