Those are drugs. The use of made up terms like coping mechanism only masks the real problem. Using drugs is solely an exercise in self injury. The reality is that addicts lie and can’t admit they are addicted to self harm. People who aren’t addicts don’t understand that. There is no such thing as a coping mechanism. Only causes and effects. Harming oneself is pathological and almost always taught by morons who are actually training others to self harm and call it “coping.”
