If you know of anyone who is struggling with a loved ones addiction, I know of a great charity that supports people nationwide. The family support programme is remote and they help many families a year. Please see link and fill in the referral and someone will endeavour to respond within 24 hours.

They also provide free treatment to the substance user if they want the support themselves( under the adapt programme on their website)
Just done half an hour on Adfam. So will do some more tomorrow and see what comes from it!
