ADAPT: telling 6th graders about drugs?

So in the ADAPT club we will be going to the 6th graders to talk about drugs and drinking and how to not be influenced. We will be presenting them powerpoints and all about it. I just don't see how it's going to help at all because eventually, all of them are gonna end up drinking and doing drugs because that's just high school. Everyone will be influencing one to the other. It honestly is a stupid thing to do. Even though we will be telling them all about it, i wonder if we are gonna end up saving at least one person from doing it.
