I knew a guy who microdosed weed from his teens in the early 70's until in 2003 when he couldn't get any weed for weeks. Hardest sanest worker before. No time off ever... but he was a dangerous wreck over those weeks.
I was working a temp job in the mid 90's in the US, and had smoked the night before. Craft foam joint... pattern cuttings... put half my finger through a bandsaw. Quickly taped it up in cellophane and pretended nothing was a matter. They chased me for weeks to do a drug test, but were too late. Lol
The time I shot myself with a staple gun was their fault. I wasn't tall enough for the assembly table so they had me stand on pallets and I misstepped and grazed my leg. The staple went into my sneaker sole
