Roofing's a helluva job. If I was a roofer, you'd damn well believe I'd have a beer+ before work.
People seek pain management where they can get it, and alcohol isn't the worst.
You misspelled meth. Roofers do meth. Outdoor trades do uppers. Indoor trades smoke weed. Everyone smokes cigarettes. Except the electricians, they smoke pole. Everyone knows that.
Lol. I knew a lot of framers who drank (lunch) and smoked (always) pretty heavily.
