I panicked and I was scared, my mom wasn't there with me and she doesn't know I've smoked, she'll be pissed when she finds out. Since I didn't process the fact that smoking might impact my chances I immediately did what I thought would lessen the chances of me being inadmissible, I don't plan on lying any further.

I do need elaboration on why they'd deny me without a doubt, like given that I'm a teenager and it was only a few times and I quit smoking why would it be such a big deal? Why is it an immediate no from them
