For me it’s driving while under the influence. If you couldn’t tell, I like me some ganja. However I have long since held the belief that it is utterly insane to drive while under the influence of most substances, with maybe nicotine and caffeine being the exception. All too often I see other stoners smoking and driving, which I simply can’t fathom. I’ve only operated a vehicle once under the influence and it was just to move a U-Haul around the block to a different parking spot, which was such a scary experience while high that I refuse to even consider getting behind the wheel again while high.
It especially sucks how that attitude will trickle down and erode the safety practices for everyone. Depending on what and where you’re learning, you can potentially end up knee deep in hazards before you even know what you’re supposed to be avoiding.
I’m an apprentice bench jeweler and the common practices in this industry are fucked. There’s a container of actual asbestos that we pack around stones to insulate them for a weld. I was looking for a good method for affixing tiny parts for welds and everyone says just superglue it, since the glue burns off and doesn’t contaminate the weld. It just depolymerizes into highly irritating gases, and benches are fucking NEVER properly ventilated. There’s oxydizers we use weekly that say “only open outdoors” on the container.
A good respirator is a great investment, pretty much no matter your industry.
