Drugs ... Why?

Why do people do drugs?

I am not asking to be judgmental, but maybe more physiological.  I really do not understand the need or desire on any scale, and I want to.

I have never had the urge or desire to try drugs, even when the opportunity to do has presented itself.  I have always said no and gone on with my night with out a second thought.  So I am struggling now to understand why someone would choose to do so especially regularly when it has so many down falls?

I guess in a sense I am kind of judgmental, as I see the people I am friends with, the people I care about as being better than that.  I tend to always look for best in people, so I see them as being people who have more self worth and more potential. I struggle with being able to empathize with their desire or need to indulge in illegal drugs because I personally have never had the desire, or urge to use. I don't want to come across as harsh, uncaring, rude or snobby.  That is not my intent, I just truly don't comprehend its appeal.  Especially when there are so may pitfalls related to its use, and the cost not only to ones physical and mental health but financially is so outrageous.

Working in the social services field, I can honestly say I have not seen one happy story come from drug use, and that is so prevalent so why would any sane person see it and say to themselves "yeah that sounds like fun I am going to do that"  even knowing all the bad that can and eventually will come from it?? Why?  Is the temporary "high" or "low" depending on what you are using, really that great that it is worth throwing everything else you have going on in you life aside for those few short minutes?

Am I the odd one for never having any desire to try them??  Is it just an innate curiosity with everyone and I am the broken one?

What makes a person recognize when they have gone too far?  That is it time to walk away, turn their back on the drug use and get clean?  Does that moment ever come with out first hitting rock bottom and losing everything?  What urge drives someone who has been off drugs for years to suddenly start to use again?  I understand that like alcoholism it can be a disease, but what puts you on the path to begin with?

I wish I knew more, that I understood more.  I am so naive, scared and unsure.  How do I help those who don't see that they need it?  OR those who are not ready to want it?  How do you just watch people you love and care about go down a dark and lonely path?

I feel so helpless...
