Story behind my topic

The reson i chose this as my topic , is alot of my friends are what you consider "pot heads" i thought this blog would be good to do so i can show them how they are affecting not only there lifes but how they perform at school. Another reason is this topic is very personal to me. I feel like many teenagers are not informed on the actual harm that smoking marijuana can do to you. I myself was not informed , i thought you just got the feeling of a buzz and thats all there is to it. I feel like this blog is a good way to inform teenagers about the acutal harm it can cause , but my question is Are teenagers well informed on the harm and affects marijuana can cause ?
