>the human reactions to those are probably evolutionary too, don't you think? I don't know. Caffeine I'm almost sure is not evolutionary even though it is positive. Regarding THC, wikipedia has this to say about cannibis: >The oldest pollen thought to be from Cannabis is from Ningxia, China, on the boundary between the Tibetan Plateau and the Loess Plateau, dating to the early Miocene, around 19.6 million years ago. Cannabis was widely distributed over Asia by the Late Pleistocene. So if it was evolutionary we would expect Europeans and Africans to be unaffected by it. Unless there are other plants that do the same. Simmilarly, tabaco is native to America, so unless there are other plants that have nicotine it doesn't really make sense. Just a guess. But in any case the usage and effect of both thc and nicotine is so different today that it doesn't matter. If humans evolved to use and respond to these drugs it would only be in low doses. And it's also not as important of an adaptation as playing and eating, especially given that Europe and Africa did not even have these drugs and got along fine. There is also no inaye drive to smoke or take drugs as there is with playing and eating. Children play with and try to eat almost everything. I don't see any children trying to smoke (not sure what an evolutionary drive for finding and consuming drugs looks like honestly). So to answer your question I don't know but I don't think it matters.

But! all those are weak neurotoxics. We might have evolved to get "high" on consumming weak neurotoxics to avoid infections (some mammals, who also happen to have parasitic issues, like cats, do the same). Drug consumming seems to be highly evolutive, even if we do not need it with modern medicine.

  I wish you would have addresses some of the specific points I made about the lower dosages and most importantly about avilablity of these drugs in Europe and Africa but I think I see your point: getting high servers as a reward for consuming neurotoxics that act to avoid infections. Even if this is true, there may not be an intrinsic drive to find and consume these drugs, but only to continue to consume them once found. In any case, this argument wouldn't apply to cocaine or heroin, because those are almost definitely not evolutive. They are hacks that bypass the evolutionary reward system. They cant be evolutive because they serve no evolutionary purpose and were definitely not available in Africa. But my main point is tgere is not "get high" drive in humans (at least before innitial consumption) whereas there are inate evolutionary drives to play physical games, eat, and be in the sun: that is to say, before ever being exposed, an innate (and useful) addiction.
