Opinions on smoking weed?

I am into this guy only thing is he smokes weed & I dont. I don't care what people do as long as it doesn't make u a whole different person u know like some people alllll they do is smoke. But any experience where one person smokes and one doesn't? Were both 19 and personally I wanna wait till I'm legal to do it lol no hard feelings. I have friends who drink everyday, smoke a lot, rave, whathaveyou but I'm a small lil homebody who is there when they need takeout and cuddles lol
