These things make me wonder how soon until all of our life will be based on medicated states. Take a smart pill for work, and a fun pill for the pub...
While Modafinil and similar "smart drugs" currently don't actually improve cognitive functions all that much and are most like a nanny for your brain telling you to stop watching cat videos and work what happens when a smart drug will actually hit the market? It only takes a tiny fraction of the workforce to be taking those to create an avalanche.
If true smart pill will hit the market that say increases your cognitive function and concentration and straps say another 50 or 100 IQ points (i know it's a bad measurement unit for this but i don't have a better one) on you then even a single average guy in your workplace is enough to trigger this. This is the same reason why we do not allow performance increasing drugs in (most) sports, it's not because it's unsportsmanlike or because they are scared people will stop watching, it's because even a single athlete on those forces everyone else to take them just to even out the playing field.
