"Archaeologists have found evidence of kola nut (caffeine), tobacco (nicotine), khat (an amphetamine-like plant), betel nut, and coca, at various sites dating back at least 13,000 years, indicating that humans have, in fact, been drug users for a very long time. Across the globe, people in non-Western cultures are very familiar with these and other mind-altering substances."
