In the real world, NOT the world of a few ignorant American kids, a “vegan” is a vegetarian who also consumes NO animal products of any kind. Probably they also avoid things like wool, leather and silk.
Therefore, there’s NO reason why they would be more likely to avoid drugs - that would be crazy.
Just about the only way a person could avoid things tested on animals would be to live as a hermit and produce everything they used or consumed from things they had grown themselves.
Update, you have an answer from one of the idiots I was talking about. Here is “the definition” of vegan:
Some people feel they can redefine words to suit themselves. I'm an old man. “old man” means a fair-minded, intelligent person who is always right”.
@ chukabutty, I wouldn't assume from “ONE question” anything about “the entire Americas” but I know that usually when people use the term “American” they mean “people or things from the USA”. From your comment you have some odd ideas but surely you'd accept that MOST of the contributions to this section are from American and that it's frightening how ignorant and misinformed THESE people are about something as basic as food. Thinking about some of your past comments, you're not so bright yourself!
Eaten any “expired” vegetables or eggs lately LOL
