Adjusted comparisons of indicators heavy and/or problem marijuana use across Marijuana-only and CBD+Marijuana co-use groups

	Marijuana-only use (n=613)	CBD+Marijuana co-use (n=249)	Group difference
Amount of consumption	M (SD)/%	M(SD)/%	p-value
Frequency of past-month marijuana use	11.1 (11.0)	14.0 (11.6)	0.0009
Heaviness of daily marijuana use (# times used per day)	2.5 (3.3)	3.3 (6.9)	0.04
Poly-marijuana product use
Number of marijuana products used	2.7 (1.7)	3.6 (2.2)	< 0.0001
Indicators of Problem Use
CUD (CUDIT Score)	1.3 (2.4)	1.6 (2.6)	0.07
Solitary marijuana use	69.8%	76.7%	< 0.05
Marijuana use-related consequences
Number of negative consequences endorsed	16.3 (8.8)	17.0 (9.8)	0.40

Note. Group differences for Frequency of past-month marijuana use, Heaviness of daily marijuana use, CUDIT score, and Number of negative consequences were assessed using separate ordinary least squares regression models; group differences in poly-marijuana use (# products/methods used) were assessed using Poisson regression; group differences in solitary marijuana use were assessed using logistic regression. Models controlled for age, gender, race/ethnicity, mother’s education, and CHOICE intervention group at Wave 1.
