It weakens you. Turns you into a docile, compliant, brainless creature to be manipulated by the ruling class. They love people like you, because you'll do anything they say, you're so easily duped by them. All due to your crippling addiction.
If you quit, many of these problems will become fixed. You don't realize how much it will help your struggling 'mental health' to simply quit. It's also easier to quit than you think. This may sound insane, but if you believe and if you ask, God is willing to help you. This is because he loves you more than anybody in the entire world. Ask him for help at your moment of temptation, even within your thoughts, and he will help.
