I've been close to drug users. I feel content about the image presented by TV shows. But i have opinions on it.
-The image is correct. We should not complain about how the image been presented in TV programs because it reflecting the reality. The image is certainly negative and it can not be translated to other images! The fact is someone who do drugs (without requirement of any medical advisory) they are careless about themselves. How can they possibly care about the person next to them? One way or another they'll end up losing everything they've got then doing everything to earn their daily drug fund and they start to show abusive behaviors so the image is pretty dark.
-But we have to make sure we also share this possibility that every drug addicted can change. They can return. The stories behind every drug user can go different. Thus we can not get our back on them and never consider them part of the society. They can be fixed. We must give them the opportunity, try to help and see who worth it, who want it or who don't.
And i just feel sorry and sad for every drug user who brought their lives to struggles. It's not a happy image at all.
