That’s what has already long since happened.
Pain management in the United States is an absolute nightmare of nanny-state overregulation and prohibitionist Puritanism - a 200 proof cocktail of pure tyranny.
What an individual chooses to do to manage their own pain - whether physical, mental or both - is rightfully nobody business but their own.
I confess I struggle to comprehend the level of self-righteous arrogance it takes to appoint oneself the dictator of others’ choices in this matter.
I remember when my spouse was undergoing chemo treatments, her bones would ache deep down. They changed the schedule on her pain medication and made it more difficult to acquire. The rest of society suffers because of a few bone heads who OD. Great plan.
