Most annoying video ever. Why can't you find an American educational clip that doesn't leave you with your head in your hands and your fingers in your ears!?

Does this stuff cross the blood-brain barrier enough to make a difference?

One problem with artificialy increasing neurotransmiters is chemical adaptation. Repeatedly flooding your brain with dopamine results in tolerance. You're right though, a little here and there is perfectly fine. Human beings dont usualy stop "here and there". haha.

the guy is right though the caffiene does increase dopamine in the brain, and in moderate doses it helps improve memory....overdo it though, then that's not good.

I don't have really nothing against taking drugs, everybody is free and should do to himself what he wishes, but i am against earning money from selling any kind of dopes, this is where evil comes from, in this subject. If there was no alcohol, caffeine and nicotine in stores, there would be almost no drug users, because ppl would not bother growing this stuff for themselves.
There's no fucking science here. These people are full of shit.
