So here I have this temporarily debilitating condition... if rest, ice, and OTC pills don't clear it up in a few weeks, there's the (eek!) surgical option.
The pain, when I try to move around to get to places where work is to be done (such as the next room; forget about the consulting-company lab) is such that by the time I get there I can't actually accomplish anything.
But, it's temporary. Last time, it lasted about a month. This time, I'm taking more care not to aggravate it... maybe it won't last as long.
There's a nontrivial percentage of the population with chronic pain, as bad as mine or worse, forever. In order to be even remotely functional, these people need serious pain meds.
But! We can't have them becoming dependent on those meds, can we? Oh, no indeedy! That would be as bad as letting terminal cancer patients have heroin, and perhaps become addicted in their final weeks of life! We need ever-stricter laws on the dispensing of effective pain medication to protect these people from themselves.
And just what is the constitutional justification for the Harrison Act, anyway?
