Prayer For Overcoming Drugs

Dear Lord, I feel I have made such a mess of my life and have allowed drugs to take possession of me, which I now confess is a drug addiction. I know that this is not only dangerous to my health and distressing to those that I love, but I realise now that it is very dishonouring to You.
Thank You, that You are there for me and have never given up on me. Thank You, that You died for me and that Your blood has cleansed me from all wrong and unrighteousness, even this drug abuse that has caused me and those close to me, such pain and distress.
I pray, that You would give me Your sufficient grace, which You have promised to all Your children, and ask that You would help me to break free from this destructive drug use. Wash me and I shall be whiter than snow. Cleanse me I pray with the blood of Christ, so that I may be clean and freed from this enslaving habit, and fully and finally be enabled to overcome drugs in my life. This I ask in Jesus' name,
