I'm going to bust my ex-friend for doing illegal drugs and selling them at our school
Is there a reason why you want to bust your ex-friend for doing and selling drugs at you school?
Yes, he's been doing it often. I also think he will want to bust me using drugs when I do it.
To be honest you shouldn't be doing drugs. He should be reported to the police for selling drugs while you should seek therapy for doing it. It's illegal and you should know better than to do drugs that will have a detrimental impact on your health.
Screw it, I am going to bust him. If I get in trouble, I don't care.
It is good that you are going to report him but you should also seek help. It is not good for you to continue to use drugs. If you need help stopping you should seek help.
