I took a little bit of e (half a tab, even though that's not a measurement) while working at a plastics factory. Interesting night.. I was put on cardboard detail, back in the very back of the factory.. which was nice because I could dip out the back bay-door without anyone noticing, to take a smoke (nicotine) break... and nobody else was really back around there that night.. .but I got a few visitors, randomly people just stopping by, other workers. I guess I was nicer to be around in that state.
Also, the job that night entailed cutting up cardboard into small pieces to put into a compressor, and yea--- that's why I had visitors.. people bringing more boxes. Anyways, I was making designs out of cardboard all night, because the box inflow was slow, and at my normal pace I'd be done and would probably be told to do something else.
Smoked weed when I worked at a pizza restaurant in high school, usually with a manager.. and once took acid (that my shift manager let me store in the freezer for the night) about an hour.5 before we closed.
Smoked with the whole crew, basically- one christmas when we had a regional get-together.. managers and employees. I don't remember the get-together, other than feeling a bit noid (we all did, as the regional manager was there, and was known to be kind of an ass, even though also cool... Also, one of our managers, who wasn't in attendance, was a Sheriff as well).
Smoked weed quite a bit on a construction job, fence construction.. so nothing entirely dangerous.. my coworkers would sometimes smoke crack, drink, take various painkillers and xanax.
