Nor-BNI (3.2 or 10.0 mg/kg, IM) treatment effects on group mean (N=4 per group) cocaine intakes (mg/kg) during both the cocaine vs. food choice and the 20-hr extended cocaine access components of the daily session.

	Choice session cocaine (mg/kg)	Extended-access cocaine (mg/kg)	Total daily cocaine (mg/kg)
Choice session only	1.25 ± 0.14	—	1.25 ± 0.14
+ Extended access – 7 D	1.10 ± 0.21	6.15 ± 2.22	7.25 ± 2.08
+ Extended access – 14 D	1.20 ± 0.18	5.91 ± 1.89	7.11 ± 2.00
+ 3.2 nor-BNI – 7 days	1.04 ± 0.23	6.41 ± 1.37	7.45 ± 1.31
+ 3.2 nor-BNI – 14 days	1.18 ± 0.11	6.33 ± 1.41	7.51 ± 1.30
Choice session only	1.19 ± 0.16	—	1.19 ± 0.16
+ Extended access – 7 D	1.06 ± 0.22	7.32 ± 0.53	8.38 ± 0.67
+ Extended access – 14 D	1.08 ± 0.24	6.96 ± 0.67	8.04 ± 0.81
+ 10.0 nor-BNI – 7 days	1.18 ± 0.09	7.08 ± 0.51	8.27 ± 0.48
+ 10.0 nor-BNI – 14 days	1.21 ± 0.15	5.83 ± 1.48	7.05 ± 1.38

Data represent group mean ± 95% confidence limit cocaine intakes of the last 3 days means of each 7-day experimental condition for individual monkey.
