A Drug to Cure Fear (2016)

People have been getting results like that for that drug for a long time

It reminds me of the similar use of MDMA where I once started spooling rather dispassionately the details around a series of traumatic events including names, places, etc.

The other day I was in grips with another traumatic event series and told the people I was with that "if I took MDMA I could..." and seriously thought about taking the MDMA but after describing the MDMA effect in detail, I started to spool the memories exactly the same way without the drug.

The hypothesis that blocking noradrenaline (norepinephrine) is the mechanism of action here doesn't make any sense.

In fact nothing about what the author states about noradrenaline makes any sense. It just doesn't work like that.
