"Abuse" is a leading term. It's possible to take drugs without it being an abusive situation. Almost everyone already takes caffeine daily and hardly anyone considers that abusive. So therefore we should put substance usage into two categories: "abusive" and "safe". "Abusive" substance use means that it's affecting either your health or your relationships. " Safe" substance use means that your life is generally improved and your long term health is not affected. Of course it's a spectrum, not black and white, but it's a good starting point. Where a drug end up on this spectrum is a personal thing. Marijuana, as long as it's not smoked, falls into safe usage for many people (not me, it gives me anxiety). Coffee is safe (again, for most people). Microdosing psychedelics may be safe. Likewise, occasionally using modafinil may be safe. Treating conditions also falls into "safe" usage even when there may be some mild negative health effects - it's a tradeoff. One that is best just by a health professional, but that's not always possible or desired by an individual. I suspect that many workers who use amphetamines may have underlying adhd and they use it ameliorate that. Others probably just like the energy. In the latter case, as long as it's occasional and doesn't affect your relationships, this is probably ok. Amphetamines absolutely do have the potential to be abusive, but for many people they are not.
