For example, only 3.4% of trauma-exposed participants in our larger sample (n = 1,029) reported only using marijuana in the past month (i.e., no alcohol or other substance use), meaning that any evaluation of “past-month marijuana use” participants would actually be overwhelmingly comprised of alcohol-marijuana polysubstance users.	cache/cannabis-31.pdf	txt/cannabis-31.txt
