I just don't think it is a good analogy for hardcore drug use. Many of us did not choose to start taking drugs. Not with any real sense of context. The consequences are very often "not real" until they become "all too real."
A better analogy, would be "What do you do when you find yourself in a car moving at high speed with no brakes and no control over speed?"
This analogy specifically does not mention how you got into that position. Because its sort of irrelevant how your brakes came to be shot. What is relevant is how you can stop without causing damage to anyone else - in this situation, like with hardcore drug use, everyone involved is a victim. My point here is that recovery and harm reduction are not about casting blame. They are about finding a damn barrier to run into instead of a minivan full of kids.
