Quarterly trends in past-month cannabis use in the United States, 2015-2019.

ABSTRACT:

Background

Prevalence of cannabis use has been increasing among select subgroups in the US; however, trend analyses typically examine prevalence of use across years. We sought to determine whether there is seasonal variation in use.

Methods

We conducted a secondary analysis of the National Survey on Drug Use and Health, a repeated cross-sectional survey of nationally representative probability samples of noninstitutionalized populations age ≥12 in the US. Quarterly trends in any past-month cannabis use were estimated using data from 2015-2019 (N = 282,768).

Results

Prevalence of past-month cannabis use increased significantly from 2015 to 2019 from 8.3%-11.5%, a 38.2 % increase (P < 0.001). Prevalence increased across calendar quarters on average from 8.9 % in January
