Addict, could someone check ? I think it is a noun and it can describe a person who is addicted to something. Addicted people usually don’t see a problem. If we see that somebody seems to be addicted to something we should tell this person that particular activity or habit is no good for their health or influences their lifes. Then this person might agree or disagree. We can keep informing about side effects but the most important thing is to realize by the person who is addicted that there is a problem. After somebody has decided to stop doing something but can not overcome it then he or she should go to doctor and start therapy. Sometimes pills or hospitalization is needed.
