If it isn't Meth, these folks will find something else, we are not all equal when it comes to strength of character...

Life isn't fair...

You are correct:

It's the addict, not the drug.

Let's say that the meth problem could be "solved" by installing a "smoke detector" like device in every home that would detect meth. Would you be in favor of that kind of solution, or not?

That is naive. Try testing your own strength of character against meth or cocaine.
