This is an interesting article for several reasons.
1) I know people affected by this situation,
2) the problem caused by legalizing marijuana was not limited to the alleged health consequences of using marijuana, and
3) it shows that even "legalizing" something doesn't mean people are free...or more free. Here, the post-legislation bureaucracy created potentially a worse problem by jeopardizing citizens' livelihoods.
(The conclusion to be drawn is that enacting laws - regarding specific acts or choices or goods - beyond the already broadly stated mandates of the U. S. Constitution is virtually always actually unconstitutional and destructive.)
Examples:
Seat belt laws don't save people. People using seat belts do.
Gun laws don't protect people. People safely using guns protect (i.e. don't kill) people.)
Laws are an impotent tool when people are free. People who would choose to do something that might harm themselves or others will likely disregard laws intended to protect.
