My firm has been in operation for almost twenty years. The most common addiction, even if you don’t get physically hooked, are uppers. Ritalin, focalin, energy drinks, etc. Anything that gives you hyper focus.
As far as consequences go, I had four stents installed at 44 and cancer at 49. It should have been a bypass but my surgeon is a fucking rockstar. Had I not given up red meat in my twenties, I probably would have had a massive heart attack before forty.
Mental health is always a struggle, but we try to implement as many safeguards as possible. It’s still not enough.
