That's the problem with pot. Train of thought usually turns out to be a train wreck.
That may be a moral judgment to you but a reasoning adult can easily see that it is more properly a pragmatic distinction based on objective definable differences between adults and minors.

How you can equate civil laws governing a public thoroughfare with a moral judgment is beyond my ability to imagine
Thanks for proving my point about your convoluted thinking. A very simple distinction between a pragmatic moral judgment and a judgment of social mores was too much for you to process.
