In 2013, more than 175k kilograms of legal speed products were sold in the United States. To put that figure into more realistic terms, it would be enough for every single American to use 27 Adderall tablets. Considering the US contributes just 4% to the world’s population, it means that 70% of the world’s legal speed gets produced by Americans.

Speed drugs have been illegal for decades in recreational use, but because of the rise of stimulant treatments for ADHD and other childhood disorders, legal tweaking has become more normal than ever before. Young men in particular are getting prescriptions for Adderall, Ritalin, and other stimulants so they can “pay attention” in school.

Although stimulants like Adderall have been prescribed for over 80 years for ADHD and other issues, adults are using it today like never before. Lawrence Diller MD told High Times. “I’ve watched with worried vigilance for the past 15 years the growth in the use by adults of these potentially powerful and addictive drugs. Sadly, I believe only after stimulant abuse causes the deaths of enough young adults will we address this growing public health menace.”
