	LRHD (n = 53)	MRLD (n = 214)	HRHD (n = 126)

Delay discounting

O_max	5.852 (0.446)^ab	14.244 (0.619) ^ac	25.242 (0.991) ^bc
Elasticity	0.315 (0.026)^ab	0.112 (0.006)^ac	0.059 (0.003)^bc
R-Ratio	0.320 (0.023)^b	0.325 (0.011)^c	0.371 (0.015)^bc

Note. SE = Standard error. LRHD = low reward value, high discounting; MRLD = moderate reward value, low discounting; HRHD = high reward value, high discounting; R-Ratio = proportionate substance-related reinforcement. Columns that are significantly different from one another share a superscript such that:

= LRHD vs. MRLD

= LRHD vs. HRHD

= MRLD vs. HRHD.

Significant differences were tested using Wald’s Test.
