While Bupropion has been nick-named "poor man's cocaine" is is not, as the show stated, "highly addictive". It is classified by the FDA as "non-addictive" and "non-habit-forming". Although the US government classifies Bupropion as "non-abusable," animal studies with squirrel monkeys and rats show they can be induced to self-administer bupropion intravenously, which is often taken as a sign of addiction potential. Bupropion is reported to be abused in the United States and Canada, notably in prisons.
