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...
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.
