I'm not saying drugs are good in any way, but to get addicted you need to use them more then is "safe" for your body and mind.
Most people are in my opinion are able to recognise this line and stay a healthy distance away from it, yet so many succumb to it and become addicts.
So upto the point where a person actually is addicted, which is probably alot earlier then when he becomes aware of it, he will still have made conscious decisions to take drugs and increase the amount of drugs hes taking, neglecting the fact that hes going to far with it.
So in my opinion for each addict saying he once was in control, i think there are several more who stays in control.
How often a person uses drugs i think is also very related to his social circles and wether his friends will tell him to get a fucking grip if they feel he's slipping or if they will just feed him more.
As for knowing all this, i can't really know much without having done extensive research,
But suppose i hang out in some social circles where drugs are more or less accepted but not used much.
I'm not saying i use drugs here, but i know for a fact its possible to go for years and use drugs on occasions and not become addicted.
This all being said it's also important to recognise the differences in drugs, some are alot more addictive then others.
And once you cross the line and start injecting drugs into your body you're pretty much there already...
Hope I haven't derailed the thread to much here
