Previous research has provided evidence of cognitive dysfunction (specifically decision making and impulse control) within individuals who have used methamphetamine heavily in the past. Furthermore, research has indicated nicotine stimulates these same functions. This study evaluated the theory that nicotine may compensate for some of the reduced function caused by methamphetamine use. Sixty participants were recruited. Twenty participants were previous methamphetamine users and current tobacco users, 20 others were previous methamphetamine users and current nontobacco users, and 20 were nonmethamphetamine and nontobacco users. Cognitive assessment was completed using the Stroop Test. Results indicate significant differences among the control group and the two methamphetamine-using groups. However, results did not support hypotheses related to differences between the two methamphetamine-using groups. No causation can be determined based on this study because many limitations were identified during the study process.While the health effects have been well-publicized in the media, it is tobaccoa#39;s addictive qualities that keep many using. ...
