Hierarchical multiple regression analysis for variables predicting weekly cannabis use (gram) at 6‐month follow‐up in heavy cannabis users (n = 29)

	B	SE B	β	P
Step 1: Change R 2: 0.41, f 2 = 0.70				<0.001
Baseline weekly use	1.10	0.25	0.64**	<0.001
Step 2: Change R2: 0.18, f 2 = 0.44				0.002
Baseline weekly use	1.28	0.22	0.75**	<0.001
Behavioral approach‐bias	0.02	0.01	0.44*	<0.002
Step 3: Change R 2: 0.11, f 2 = 0.37				0.006
Baseline weekly use	1.14	0.20	0.67**	<0.001
Behavioral approach‐bias	0.02	0.01	0.35*	0.005
Working‐memory network	0.28	0.28	0.35*	0.006

Final model R ²: 0.70**, adjusted R ² 0.67*. SE: standard error.
