When I was 17 I was prescribed xanax 3x daily. The doctor told me to take the first pill in the morning to prevent any panic attacks before they start, and to take the other two as needed. I was younger then, and didn't think to do much research on the drug. All I cared about was getting a good nights sleep for the first time in 3 months, since my anxiety had been so bad that I was up all night reading psychology books about what could be wrong with me, and also driving myself to the hospital when I had very bad panic attacks that were impossible to tell apart from heart attacks.
I didn't even know what withdrawal was when I was first prescribed the xanax. I just read the pamphlet that came with the prescription. I was 17, and I trusted the doctor. Nowadays I do research on anything I may take, but back then I didn't really think to.
There are plenty of chronic pain patients that are prescribed opiates daily for long term treatment. Most of them 'cross the line' without knowing it. Also, I have the self control to limit myself to prevent physical addiction most of the time. Psychological addiction is completely different though. When I took 3-4 month breaks at a time, I was still thinking about when I would finally get high again. I removed myself from the 'people, places, and things' that had to do with drugs, yet drugs were still a big part of my life even when I wasn't using.
The way that I look at it is nobody in their right mind would do half the things that addicts do, so there is clearly something wrong with them. I've seen people go from million dollar houses to the streets. At that point, their addiction is influencing all of their decisions, and I don't think that it is all a matter of self control.
Not all addicts are physically addicted. I did "man the fuck up" and stop using, but mentally I am still addicted. How do you explain that? I have done all the right things (stopping use, moving away, getting new hobbies, friends that don't use) yet I still think about drugs all the time. I'm still an addict, whether I'm using or not. That's why I view it as a disease, or at least a disorder.
