Some people are more addicted to money, careers and being "successful", whatever that means, than just about any substance out there. To say that drugs of any kind are an indication of a lower quality of life is to assume that (1) people should conform to a certain standard of life and (2) that exposure to substances results in a different lifestyle and not the other way around and (3) that there isn't a demonstrable sample of the upper class that misuse drugs on a VERY similar scale, just different mediums. Western culture is so devoid of any kind of macroscopic thinking or spiritual discovery that you have people who have no idea how to achieve these alternative perspectives and misuse the tools; Drugs. And on the other side of the same coin, you have people who think that the very act of trying to develop a different perspective with the help of substances is some kind of death sentence in an absolutely absurd and trivial game of "who can have the best life". Graphs, charts, and data isn't going to help the West figure out how to properly manage tools for alternative perspectives without hurting themselves or, at the very least, starting just another vicious cycle of confusion in their attempt to escape society or culture. What we need is a better foundation for how we view the games we play in society so that people no longer feel held captive by it. The very notion of needing to have a career or life unhindered by drug use is the very catalyst of drug use. This is like telling people that the more money you have the better and then being surprised when greed overthrows virtue.
