Many people argue that everyone can fight and beat their addiction, and that you should never give up on an addict. However, after watching some YouTube videos on drug addicts, I've seen some people who seem to have reached the point of of return. They simply aren't there anymore, and can't even think straight, and sometimes don't even seen human-like with their behaviors. I saw one woman who acted extremely similar to the possessed girl in The Exorcist. Are there some addicts that simply cannot and never will recover?
