FAAH and post-traumatic stress disorder: Considering the ERCs may exert so-called entourage effects to AEA, potentiating AEA’s effects through activation of other receptors such as the transient receptor potential vanilloid channel (TRPV1) [28], and also being metabolised amongst others by FAAH [29], it fits that findings also document reductions in AEA and ERCs after trauma and in PTSD [21].
