Bramness JG, et al. – Researchers investigated whether cannabis use increases bronchial asthma risk via data analysis of 2,602 young adults followed for 13 years in a population-based longitudinal study—in addition to information obtained from the Norwegian national prescription database regarding asthma medication (β2-adrenergic receptor agonists and glucocorticoids for inhalation) prescribed. Researchers evaluated current cannabis use, sex, age, years of education, body mass index, and current smoking habits. The following factors were reported in association with the prescription of asthma medication: female sex, self-reported earlier asthma and allergies, daily tobacco smoking, and current cannabis use. According to the findings, cannabis conferred risk for bronchial asthma or use of asthma medication even when known risk factors were taken into account. Those at risk should avoid cannabis intake via smoking.
