Dude, you need to stop doing shit.

For the mean time, just STOP the smoking. STOP the drinking, just don't even bother with anything that will or could get you in trouble.

You got caught. Soo, you did it again. If you didn't like the consequences the first time you should have "learned your lesson" and not have taken any risk where you could get in trouble. I mean, its one thing to smoke and drink, but another to bring it to school or carry it anywhere that could get you in serious trouble. Caught by parents, one thing, by law or other authorities? Totally different.

Remember, each time you are caught, the consequences will get worse and worse.
