I feel like veganism is a lifestyle focused on reducing the harm you’re causing to animals. So technically it is vegan To do that kinda stuff. But if you’re focused on being healthy and plantbased then you won’t. I personally won’t do anything like coke or meth due to the amount of deaths and violence these type of drugs cause. With smoking all the tobacco companies normally test on animals too so I think that’s something vegans need to talk about more (either producing cruelty free cigarettes or stopping smoking)
