In brief: Best to ask
The best thing to do is to ask your teenager if they are smoking.
Your doctor can run tests to see if nicotine is present in your teen's system, but most (if not all) physicians will not test teens for any sort of drug use without the teen's consent. So, this is really a conversation you should have with your teen, instead of a test. Honest communication is invaluable.

In brief: A good conversation?
There are urine tests for the major metabolite of nicotine, cotinine, and these are available over the counter. There are even some tests that can be put into toilet water. However, more important than knowing if s/he is smoking is having a good, honest, trust relationship with your teenager. Doing things without their knowledge or consent and behind their backs can do far more harm than good.
