That is true there is a big difference between dependence and addiction. Heroin is legal in England because I believe they did studies on it and at the right dose for relieving pain people don't get addicted. That doesn't mean there wouldn't be withdrawal though.

I am an addict by nature (recovering) so it is easier to look at it from that angle. There is a chance I would take more than prescribed and then look for more.

I take klonopin which is an addictive drug but I take it as prescribed and no more and I don't feel an urge to take more. I am not addicted to it but my body is becoming dependent on it. I need to cut my dose in half and see what happens.
