The origin of the immediacy of this issue is twofold.
Firstly, the problem concerns drugs which are already legally,
safely and widely used amongst patient populations
[2]: Ritalin/Adderall for Attention Deficit Hyperactivity
Disorder (ADHD) and Modafinil for narcolepsy.
Secondly, this method of enhancement is one that is actually
in current use in an entirely unregulated fashion, by
a significant proportion of the population. In the U.K.
Ritalin and Adderall are considered class B drugs [3],
punishable up to 5 years in prison for possession, and
Modafinil is considered a prescription only medicine [4].
