This app is a well-intentioned one, but if someone needs information about alcohol, for example, you have not to say anyway that 1 or 2 cups of beer a day is "harmless". If you drink even 1 drop of alcohol it will damage something in your body, be sure. I am 17 years old and I never used any kind of drugs, even coffee. I live a very happy life with my family, and Im not waiting for my 21 to start drinking or smoking, I will continue my life without drugs! :D And, for the rest of the app, congratulations, good job!
