that must feel terrible thinking you could have stopped him when you had the chnace.. but really if his mind was made up nothing you could have down would stop him

it sounds like you're not proud of turning to drugs, do you want to kick the habit? i'm sure your friend would definately not want you to end up in the same situation he was and would therfore reccomend you to stop now before you get out of your depth, what kind of drugs are you taking?
