No more so than the FDA discouraging the use of the deadly nightshade (belladonna) but endorsing the use of atropine produced from the plant.
The FDA, and the medical community in general, do indeed discourage the use of belladonna. However, the FDA/govt hasn't sought to prohibit or control that plant have they. And yet, considering how many have died from each plant I'd say someone has their priorities wrong.
Neither is any organization pushing the FDA to approve belladonna as medicine. What's your point?
The government of Louisiana has.
