There is danger in this substance that makes you temporarily crazy and illuminated about self-control and responsibility. I think that the true nature of the danger is neither physiological, nor psychotogenetic, but rather, metaphysical or existential, as in the terror of Truth confronted in the Eleusian mysteries. Some people flip out and endanger people - but this is not itself the essence of the danger. It is responsible to acknowledge that this is dangerous. Of course, just because something is dangerous does not mean that it should be demonized.
Real men develop their souls by confronting danger.
Life itself is dangerous, but the government should not try to prohibit contact sports and rock climbing. This is an absolutist health fascist attitude. Absolutist attitudes are as unrealistic and unreasonable, as they are simple and easy to propagate. One guy online told of how he flipped out and trespassed and brandished a knife at a stranger in his house. However, I have ample evidence that LSD causes people to think alarmingly about the possibility of flipping out and transgressing self-constraint.
