Interesting publication . . . To summarize . . .
"The study suggests cannabis was being smoked at least 2,500 years ago, and that it may have been associated with ritual or religious activities. Traces of the drug were identified in wooden burners from the burials. The cannabis had high levels of the psychoactive compound THC, suggesting people at the time were well aware of its effects. The burners, or braziers, were found at Jirzankal Cemetery, high up in the Pamir Mountains. Cannabis plants have been cultivated in East Asia for their oily seeds and fibre from at least 4,000 BC."
"It's possible the high altitude environment caused the cannabis plants in this region to naturally produce higher levels of THC. There's evidence this can happen in response to low temperatures, low nutrient levels and other conditions associated with high elevations"
