I would expect taxation of all of these -- synthetics included -- to buy the appropriate certification and regulation.

It's also worth noting that the toxicity for some of these, including LSD, is so ridiculously low that as far as the science goes we should be much more concerned about moonshine than blotters.

The LD50 for THC, last I ever heard, was over 40,000. Technically water is more dangerous.

It's not technical - people die from drinking too much water. https://en.wikipedia.org/wiki/Water_intoxication

Study citation needed, or this is the very definition of FUD.
