If you need treatment for drug addiction, you're entitled to NHS care in the same way as anyone else who has a health problem.
With the right help and support, it's possible for you to get drug free and stay that way.
A GP is a good place to start. They can discuss your problems with you and get you into treatment.
They may offer you treatment at the practice or refer you to your local drug service.
If you're not comfortable talking to a GP, you can approach your local drug treatment service yourself.
