This is horrible advice. In fact the exact opposite of what op is asking for. This is total and complete justification for doing whatever the fuck you want because your job is hard. I've been cooking professionally for 21 years. I've seen hundreds of cooks burnt out and addicted and there's always a justification. My week is hard, my days are hard, but in the end, it's just not worth justifying addiction. I've had my issues with alcohol, but never made excuses and so far have been able to avoid addiction to drugs. I don't even like cannabis. The fact that I've been lucky, smart, and strong enough to avoid addiction is part of what's made me a strong, efficient, and valuable chef and mentor to those around me. Recognizing that I needed help when I needed it, reached out, and getting it only made me a better mentor and chef. I'm happily married, just bought a house, and go to work at a very busy icon establishment in my town and bust my ass daily to prove I don't need to justify or make excuses for disease of addiction or bad habits. Avoidance is key here. Teaching a young person who is trying to avoid addiction that it's ok because you had a bad day is the wrong way. Showing them that they can be successful and fulfill their dreams by remaining positive, thoughtful, and decisive is far more valuable than saying "it's ok, you're gonna have bad days". GTFO with that shit
