I feel bad because I used to be spiritual and had a passion for philosophy, but now I abuse drugs.
Oh no, what kinds of drugs are you using?
I used to smoke fake weed but now I'm smoking heroin
It is your body and you can do what you want, but you shouldn't hurt it by doing drugs. You could become addicted and ruin your life.
What do you know?
I know that abusing heroin is a bad idea, and is only going to lead to terrible outcomes for you. I think you should get help before things get out of control.
