Cannabis Consumption Among Patients With a Voice Disorder: A Multicenter E-Survey Study.

SUMMARY Introduction Legalization of cannabis consumption in the United States (U.S.) has increased rapidly, impacting consumption rates in the general U.S. population. The objective of this survey study was to establish prevalence estimates of cannabis consumption among voice patients, in addition to characterizing patterns of cannabis consumption. Methods A multicenter, anonymous survey study of cannabis consumption took place at multidisciplinary tertiary voice care clinics in Portland, Oregon (PDX) and Pittsburgh, Pennsylvania (PIT) between April 2017 and December 2018. A convenience sample of 300 consecutively enrolled English-speaking patients 21 years and older with a voice disorder completed the survey. Data were obtained on the prevalence of cannabis consumption, frequency and methods of cannabis consumption, in addition to health impacts and demographics. Results Agresti-Coull prevalence proportion estimates for cannabis consumption were higher among voice patients in PDX compared to PIT. Current consumers in PDX and PIT showed a similar frequency of cannabis consumption. Combustion methods (eg, joint) were more popular than non-combustion methods (eg, vaping) among current consumers; inhaled methods (eg, joint) were more popular than non-inhaled methods (eg, edibles). Though vocal handicap scores for current consumers were similar across sites and comparable to lifetime non-consumers who also were non-smokers of tobacco, a lifetime history of cannabis consumption was associated with vocal and overall health impacts. Conclusions Prevalence estimates for current cannabis consumption among voice patients from tertiary voice care clinics mirrored prevalence estimates reported for large, representative samples from Oregon and Pennsylvania. These findings provide valuable insight on the extent of cannabis consumption among voice patients.
