they obviously have no will power i'v been around crack heads when i was younger but knew if i tried it i would be a bit of a twat so always stayed well clear and glad for it too, people just try it think it's good then get quickly hooked, i no getting addicted to something can be quite easy i smoked weed for years but gave up smoking at christmas and haven't touched anything since so no it can be hard to become un addicted, and i actually got bored of smoking it and realized how it was turning me into a cabbage and a bit of a lay about but smoking a bit of weed and injecting crack are different ends of the spectrum all together.

also i think people that smoke crack might not be as messed up but when you come to inject thats when you have really lost your soul and are just an empty shell
