I'm a senior in college and one of my friends is not in school this semester due to financial reasons.  He smoked weed before, but in his new found free time he's added those "synthetic-weed" strains that you can buy from gas stations.  Me and my other friends have tried bringing up causally the fact that he does it too much and its going to cause him severe health problems in the future, but he always gives classic addict responses like "I don't need it, I just don't want to stop." or "I feel like it isn't hurting me and it won't in the future."  We've shown him police reports and medical studies relating to people who have been seriously hurt by these substances and he just brushes it off as the internet being "unreliable."  We've hit him with the full brunt of logic and reason, but we don't know what else to tell him, but we want to help him.  Any ideas or helpful input?
