I'm thankful you know you need help; one of the tragic side effects of some drugs (including cocaine, I'm told) is that they deceive a person into thinking drugs make them better. But it's simply not true -- as countless broken lives can attest.
Yes, I will urge you to turn to God because I'm convinced He will make a difference in your life. He knows all about your situation, and He loves you and wants to help you. And He can help you, because He can give you the strength and wisdom you need to find answers to your problem. Admit your helplessness and failures to Him, and by faith invite Christ to come into your life. Even now He is praying for you.
How will Christ help you? First, He will give you a new purpose in life -- a desire to live for God and for others, and not just for yourself. He'll also give you inner strength to face your problems and turn your back on things that could destroy you. Jesus' promise is for you: "I have come that they may have life, and have it to the full" (John 10:10).
In addition, God wants to guide you to obtain practical help to fight this problem. Look for a church which seeks to follow Christ; its pastor should know what treatment programs are available in your area. You also may find new friends there, who not only can encourage you spiritually but have faced similar problems themselves. May God bless you.
