As an additional comment about the 'white-collar' aspect of things... It's worth reinforcing the state of the job market for successful software engineers, and how that relates to drug use. I try to be productive at work, but ultimately, I'm not very stressed about financial matters or job security. After starting my career, I've never been without employment for more than a month, and almost never without it being my choice. I also have a substantial safety buffer. With those factors, I'm able to have a comfortable and relatively worry-free life with my partner, and besides a bit of recreational fun, I don't really feel a need for escape from my life. I have a bit of an addictive and depressive personality, and I could see myself abusing substances in a different life situation.
