The suggestion/allusion that the EU's GDP per capita is lower than the US due to Adderall and Dexedrine not being approved/available is wild. Kind of makes me not want to take seriously the rest of the article...
I'm not even certain it's fair to refer to these things (or modafinil) as nootropics, as nootropics (as defined by the person who coined the phrase) should lack stimulate/sedative properties.
Data is well presented but the conclusions are iffy. But hey, maybe Europe can stop limiting its own industry with regulation if they just up that dextroamphetamine dose?
Adderall is a performance enhancing drug, and widly used as such. Its nigh on impossible to compete at the highest level workplaces with doped employees if you are a natural worker.
The graph implies is that aderall causes people to perform at 150% on average if 100% of the workforce is on it. I say that both implying that aderall has such a massive objective effect and implying it is so widely (ab)used are the laughable ramblings of a psychonaut at worst and unsubstantiated at best.
