Hi Linz,
As “Can’t Take No More” said, it must be so difficult helping someone who is an adult with a problem such as this. I know you said that he has received counselling, but have you? And your family? The Icarus Trust is here to help the families as well as the users we clearly addiction has countless consequences. If you would like someone to speak to, you can contact them via email on info@icarustrust,org or on the website (www.icarustrust.org).
I hope this of some help for you.
