The best thing to do is to test it. Take a few people, kids, adult, and teen, most likely, and take their blood pressure. Then have them drink a specific amount of caffiene, such as a soda or a coffee. Wait five minutes, and test their blood pressure again. Make a chart of the differences. Make sure that the subjects are o.k. with being tested.

Oh
 
Yeah... you have to have them fill out a "permission form" saying that they agreed to help. And make sure that they haven't had any sugar or food except water for at least 1hr before your tests
