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.
I’ve found this to be true in general once I started working. I don’t feel kinda this was a thing when I was and was integrating with other students. I had to readjust my “responsible” self who actually would follow up (to people’s horror) and tell myself it’s a polite saying that people don’t mean. Like when people greet each other with “How are you?”, they generally actually do not want to know how the other person is doing. You’re expected to say “fine” or “good” and deviating from that is violating an unspoken social contract.
