Multinomial logistic regression of the association between perceived harm of cannabis secondhand smoke exposure and household rules on in-home cannabis smoking with complete ban as reference

	allowed some places vs. complete ban	Did not make rules* vs. complete ban	allowed everywhere vs. complete ban
