I do drugs even when I'm not trying to.
Are you being serious right now? Why do you do the drugs even when you're not trying to?
I am a lazy motherfucker and I don't want to enforce limits on myself.
Drugs can be very addicting. You are harming your body by doing drugs. Try to find a rehab facility to help yourself gain control of your life.
I'm not going to rehab. I like to live on the edge.
Drugs are dangerous and can have really bad effects upon your physical well-being. It is not responsible for you to just allow yourself to indulge in drugs without putting any effort into stopping. Get into a treatment program before it's too late.
