Oh competitive nerds have been abusing substances for their (often over-emphasized) nootropic abilities forever. Back in the high stakes world of nerd competitions, there were high schoolers using everything from cocaine, to crushed and snorted adderall, to nicorette gum (one guy I know ended up becoming a smoker because he got addicted to nicorette and smoking was cheaper lol). This was 10 years ago.
Our 'drug of choice' was a pot of green tea apiece (ergogenic agents like EGCG provide a much 'cleaner' and less jittery stimulant effect than caffeine), high dose B-vitamins, and a hit of coffee or no-doz just before the event . (the coach insisted on the b vitamins and probably had no idea how amped up we were on camelia sinensis and coffea arabica).
These days modafinil is gaining in popularity, along with a few abusing namenda (no joke). There are calls for various competitive nerdery organizations to start piss testing competitors. Again, no joke.
The use of psychotropic agents of any kind for anyone is an ethical morasse and it's hard to find right answers. The state of psychiatric diagnosis is such that almost anyone can be prescribed almost any medication on the basis of demonstrable 'symptoms' of psychiatric illness. From stimulants to mood enhancers to anxiolytics to antipsychotics. The use of these agents can be justified on any number of grounds for almost anyone alive. Every one of us has *some* symptom of depression, anxiety, cyclothymic propensities, or attention problems. Between the four categories, you can justify the use of almost any psychotropic medication under the sun.
And with that said, many self-medicate with broadly biologically similar substances to what doctors prescribe for people in similar circumstances. Should it really be considered a crime to 'treat' yourself?
Why is it ok for a doctor to say 'you're anxious, here's benzo.' But illegal for someone to say 'I'm anxious, I'm gonna buy a benzo from my dealer'. Or for a 15 year old to self-medicate his/her anxiety with alcohol while his neighbor gets xanax from his friendly GP?
And, well, pretty much all child psychiatric medication. Many hot topics in child from ADHD, to IED, to 'pediatric bipolar' are fraught with problems in that the primary basis for diagnosis is the child's effect on parents/teachers/caregivers rather than any level of discomfort in the child themself. Many of these issues are setting specific (ADHD), are due to poor relationships with parents/teachers, due to lack of skilled parenting, or simple immaturity.
Yeah I know, all I brought up was questions, not answers. Sorry, don't have any.
