Sentience brings a duty with it. Part of that duty is refusal to encourage drug use.
Arbitrary assertion Luis.
And it ignores the global history of philosophy, religion and art., all of which have their origins in the use of mind altering plants.
There is a complete failure here to recognise that there is a significant difference between intelligent use of drugs and the use which is pathological.
Worth noting is that the pathological use of drugs was first fostered by the British when they forced the Chinese to trade tea for opium, purely so that importing tea from China did not entail British merchant ships travelling to China with nothing to sell.
The single most influential cause of the modern pattern of pathological drug use is the US policies introduced in the early 20th century, which created a lucrative black market run by criminal organisations.
Take drugs out of the equation and there is no Greek philosophy, no Rig Veda, no jazz or rock music, and vastly less graphic art. And that's just for starters.
