The definition privileges action, which is why vegan philosophy is generally fine with stuff like foxes hunting birds but not humans hunting foxes to save birds.
Taking action to depress ants to save others would go against the ethos as defined:
“Veganism is a philosophy and way of living which seeks to exclude—as far as is possible and practicable—all forms of exploitation of, and cruelty to, animals for food, clothing or any other purpose; and by extension, promotes the development and use of animal-free alternatives for the benefit of animals, humans and the environment. In dietary terms it denotes the practice of dispensing with all products derived wholly or partly from animals.”
Smoking: easy way to quit smoking plus weed during the worst withdrawal to avoid snapping at everyone
Weed (earlier lmao, I still use sometimes but less than a gram a year really): having other things to do that require concentration and memory I enjoy. Weed is easy as it’s mostly habitual. The sleeplessness is the worst and it’s only a couple of days
Opiates: Exercise, avoiding boredom (v hard! video games, gardening, easy books, podcasts etc), lots of walking those restless nights, preparing easy food for the worst few days, counting days to know it was going to end. Be careful after surgery kids that shit sucks to come off.
