Ancient Humans Got High for 12,000 Years. Then Industry Changed Everything

Your morning coffee contains a chemical a plant built to kill insects, and your brain calls it a reward. Humans have been doing this for at least 12,300 years. Yet in all that ancient record, nobody has found signs of an addiction epidemic. So what changed, and who changed it? This video follows the evidence down through time: charred tobacco seeds in a hunter-gatherer hearth in Utah, coca leaves pressed into 8,000-year-old house floors in Peru, opium poppies in Neolithic Italy, cannabis smoke rising from braziers high in the Pamirs. Then we go into Es Càrritx, a sealed burial cave on Menorca, where locks of red-dyed hair were hidden in carved wooden tubes. Three thousand years later, that hair still held traces of the plants its owners had taken. Along the way you'll see why caffeine, nicotine, cocaine and morphine exist in the first place, why a bee remembers a caffeinated flower, and why some researchers think our pull toward toxic plants may once have helped us fight parasites. We also flag where the evidence is thin, because the past is easy to romanticize. Then comes the turning point: a pharmacist's apprentice in Germany around 1804, the first drug ever pulled out of a plant, and the two centuries of chemistry and industry that followed, from Bayer's Heroin to engineered cigarettes to OxyContin. The plant stayed the same. The brakes were removed. Watch to the end for the one idea that changes how you see craving.
