What has not been addressed is THC and the brain, which I will only
introduce.

There is vanishingly little difference between the effect of THC and
all of the legal antidepressants, anxiolytics and fr that matter
opiates. Ys there is a difference, but the difference in the brin is
not robust. Their action occur within a few millimeters of each other,
often less than that, and with reverberant re-entrant circuits their
actions are often remarkably similar.

This is particularly true in the adult human brain

Outlaw coca cola, but legitimize pepsi, and you will have an analogy.
