Temporal Trends in Young Adult Cannabis and Tobacco Use in States with Different Cannabis Policies.

ABSTRACT:

Objective

Cannabis legalization may impact both cannabis and tobacco use, given the high prevalence of co-use (including blunt use) among young adults (YAs) in the United States. The objective of this descriptive ecological study was to examine trends in YA cannabis and tobacco use from 2002-2018 in states that passed adult and medical use (AMU) or medical use only (MUO) cannabis laws during that time (N = 16).

Method

Using data from the National Survey on Drug Use and Health, we conducted a segmented regression analysis to calculate absolute percent change in past 30-day cannabis, blunt, cigarette, and cigar use between time points. We descriptively compared points of slope inflection with key legalization dates.

Results

All states showed a decline in YA cigar
