Yes. I did have a secret trick.

CBD joints.

CBD is a cousin of weed without any psychoactive properties. So it is basically just a joint of nothingness. When I was drunk and was craving a cigarette 11/10, code red style, I smoked a CBD joint that I had rolled before. Like an emergency rip chord. The downside of this is that it looks, smells, and tastes like marijuanna, so it might not be ideal for a work setting. But I wonder if there is another innocuous herb that smells like tobacco without nicotine. A quick google search showed me these but I think they are going to smell like weed too. I would search the web for something that doesnt smell like weed. Or just tell people that you are smoking a CBD cig to quit nicotine. I dont think anyone on the smoking platform out back is going to give a shit. But it doesnt get you high in any way. It also doesnt really "fix" the urge to smoke, you still want a smoke, but I think lighting something up and taking a big deep puff (10 times or whatever) was enough to bring my code red to a code yellow, which I can manage.

Another thing I will say: I think you may just have to leave sometimes and prioritize your quitting. Say you had food poisoning, just simply irish exit and deal with the fallout later, whatever. Just get out. They arent going to fire you for leaving a work party.

Anyways just my 2 cents. Best of luck to you, friend!
