There are different levels of stigma and different cohorts associated with different drugs. Netherland and Hansen further illustrate this double standard when they state that in a study of suburban meth users “many had been introduced to meth as a means of enhancing their performance and productivity at work and ‘maintaining a suburban lifestyle.'” In contrast to meth, they point out that “Adderall, a stimulant very similar to methamphetamine is routinely used by students to perform better on tests with little stigma attached to it use” (Netherland & Hansen).
