It is hypothesized that prior exposure to stimulant medication may have on later substance use, particularly illicit stimulants Research implicates that prior exposure to stimulant medication may play a role in later psychostimulant use and is effected by dose. This study demonstrates, both through experimentation and a review of the literature, how prior stimulant exposure relates to Methamphetamine self-administration. Further research is need to fully assess the impact that Methylphenidate use has in the general population regarding methamphetamine use.
