I agree with @SkyWalker.
A teenager is still growing up and the amount of jeopardizing chemicals that a cigarette has is harmful for a teen’s health.
If they want to smoke that badly, wait at least more 4 years and pay for your own addiction.
Starting to smoke because of peer pressure is immature in my opinion. I was 14 once, I saw people smoking but that didn’t mean I would smoke because I thought If I have to do things I don’t want to fit in, I’m not on the right place, but that’s a whole different discussion.
