I don't know what the answer is for the hard core addict, they've been there forever and nothing seems to work. It's discouraging to watch them interviewed on the news, because after being saved more than once, they are heading out to do it again.  But the recreational user (young high school students in particular) need to be protected, even scared to the point where they realize that they aren't invincible and can't take random pills at parties and expect to live to tell about it.  I think the news coverage on the recreational cases has been effective at getting the word out about the danger that exists, at least to the parents (who watch the news) so that they can talk to their kids (who often don't watch the news).
