Figure 1. Differential total oxycodone intake and drug seeking behavior in rats given short or long access to the drug.

Figure 1.

(A) LgA-L and LgA-H rats showed greater total oxycodone intake than ShA rats. (B) LgA-L and and LgA-H rats showed higher drug seeking behavior on WD31 than on WD5. The values represent means ± SEM. Key to statistics: ##, ### = p < 0.01, 0.001, respectively, in comparison to ShA rats; !!! = p < 0.001, in comparison to LgA-L rats. $ $ $ = p < 0.001, in comparison to withdrawal day 5.
