I see a possibility of companies marketing drugs such as Ritalin and Provigil as "cognitive enhancers." I mean, caffeine is powerful CNS stimulant as it is and it's completely unregulated. So what's to stop a drug company from making an analogue to Ritalin, or a lighter dose of Ritalin and marketing it as a brain booster? Selling it OTC? Given that the FDA is already having enough trouble regulating areas such as the energy drink/supplement market - all the different concoctions of caffeine, ginseng, ginkgo (and tons of other herbal supplements) are readily available to 12 year olds. I'm curious and a bit concerned at the prospects.
