Even though our children tend to drag us into their addiction, we have the option of being involved or not being involved. Everything that I have learned from this site indicates that we as parents should not enable our addict....which to me means...stop funding! You need to sit down and find out what ..financially he needs are for the regular style of living (not addict living) and fund him only that amount. Of course, if he is using, he will find another means of getting the drug and there is nothing you can do to control that. If he runs out of money, so be it!
