Boosting anandamide levels with a FAAH inhibitor helped reduce conditioned fear memory in a study.

“what we did what they did was they dosed people for 10 days on this drug and then we looked at stress and fear because this is something that I study this is something that they were interested in — and we did find that boosting an anomid with this drug over 10 days — was sufficiently cap capable of dampening stressinduced autonomic responses so like looking at heart rate or skin conductance I think skin conductance was the measure we did there but it's a proxy for like adrenaline release — so it blunted that and it blunted subjective feelings of stress as well so people had lower levels of saying they actually felt stressed”
