TOPLINE:
Adults using medically recommended cannabis have a higher prevalence of cannabis use disorder (CUD) and greater frequency of use than those using cannabis solely for nonmedical purposes, new research suggests.
METHODOLOGY:
Researchers conducted a cross-sectional study of more than 72,668 adults aged 18-49 years and used data from the 2021-2022 National Surveys on Drug Use and Health.
Participant classification was based on whether a healthcare professional recommended cannabis to them.
Study outcomes included past-year cannabis use, frequency of use, and the prevalence and severity of CUD.
TAKEAWAY:
Overall, 29.5% of participants reported past-year cannabis use; of these, 83.7% reported nonmedical-only use, 9.2% medical-only use, and 5.7% medical-nonmedical use. 34.8% of total participants had CUD.
Men with medical-only cannabis use showed a higher adjusted prevalence of CUD at all severity levels than those who reported nonmedical-only use (all P < .05).
Women aged 18-34 years with medical-only cannabis use also had higher prevalence of severe (7.4% vs 6%), moderate (11.6% vs 9.9%), and mild (19.8% vs 18.1%) CUD than those with nonmedical only use (all P < .05).
Participants with medical-only use also reported more days of cannabis use than those with nonmedical-only use (all P < .05), with men 18-34 years reporting 217 days vs 154 days, respectively, and women 18-34 reporting 199 vs 128 days.
IN PRACTICE:
“These findings suggest that medically recommended cannabis is not associated with reduced addiction risk compared with nonmedical use,” the investigators wrote. “Clinicians should consider addiction risk before recommending medical cannabis and, if they do, should monitor for CUD emergence.”
