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.
