This is an interesting topic. Nowadays, the American concept of "war on drugs" is really ubiquitous, but for a large part of humanity's existence, drug business was considered legitimate. Pure cocaine was freely sold in pharmacies until 1914 or so. I am not that sure if our current moral position is the final one. At the very least, marijuana prohibition has swung from almost universal to a shrinking set of the most conservative US states. Similarly, opium prohibition may not be a thing in 2050 or 2100 again.
