> In 2015 18.6% and in 2018 15.9% of respondents admitted to misusing stimulants for non-medical reasons I read the 2018 study. It should be noted that the 15.9% who reported using stimulants was for lifetime use. Of those 15.9%, 37% hadn't used them even once in the past year, and 47% had used them 1-9 times in the past year. This is a huge difference from 25% of students using "1-7X/week" like in the tweet. 1-7X a week would put them into the 50+ in the past year category, which in this study was 3% of the 15.9% of lifetime users, or 0.4% overall. Two orders of magnitude less.
