I mean, you asked for advice and Im just giving you advice. Also, I don't think finding another job would take you ~1k Hours. (4h/day 5x/week for 52 weeks). That's nearly 26 FULL DAYS you could be spending doing something that will have a much better impact on your life.

This is a horrible decision and a terrible idea. Find a different job closer, or find resudence closer to your job. You're gonna waste so much time and money just commuting to work every day

If you grab a bag of weed and then put it all into your bloodstream (smoking, eating, etc) and then somehow the cops come to your house, they can't charge you with possession since you dont actually have the physical item that the law forbids possessing.

Being under the influence of Marijuana on your own property doesn't seem to violate any law/statute that I'm aware of as long as you aren't operating any type of vehicle (car, lawn mower, scooter, skateboard, etc).

The closest thing that I can fathom you possibly being charged with is Public Intoxication or Disturbing the Peace, but even then, it would require an extraordinary type of circumstance. Pretty sure you will have no issues being high in a recliner inside your house. Dlbeing drunk in your house isnt illegal right?
