Notes: Data from the 2017‒2018 BRFSS on those states fielding both current marijuana and e-cigarette use questions describe the percent of past-30-day marijuana users who report vaping as their primary mode of consumption, by state. Dates when medical marijuana legalization went into effect and characteristics of these laws are also presented by state.18–22
Florida’s law was amended to allow smokable preparations beginning 3/18/2019. All Florida residents in this study’s analytic sample were interviewed before that date.
These states legalized marijuana from dispensaries but did not allow home growing. Thus, the effective date listed is the date that state’s first medical marijuana dispensary opened (3/1/2019 for North Dakota, 1/16/2019 for Ohio).
Oklahoma passed medical marijuana on 6/26/2018, but did not award its first licenses to patients until 8/25/2018. Thus, the latter date is given as the law’s effective date. All Oklahoma residents in this study’s analytic sample were interviewed prior to that date.
