I don't know because you have not given us any information on what they do or how long they are on there for. Maybe they are a very sincere and caring and loving person who really tries to help a lot of people out and maybe you should be alittle more understanding and sympathic toward this individual. What would be the problem if they were?
I'm in recovery for drug addiction, Meth and Marijuana I've been clean just about three months. It's getting easier every day with the help of Narcotics Annonymous and other support groups. You might be making a bigger deal about her or his time being spent on the computer. It's a hell of alot better than spending time in a crack house. Think about it. Have a good day
