“Brunet wondered if the drug could be used to reduce the emotional intensity of a given memory. He began administering propranolol to patients suffering from PTSD, then asking them to write down recollections of the traumatic event. When this process was repeated over the course of six sessions, as many as two-thirds of his patients were able to recall the event without displaying symptoms of traumatic stress.” (http://publications.mcgill.ca/mcgillnews/2016/05/16/treating-trauma-on-a-city-wide-scale/)
Seems like the choice of participants and the method was ok, but the main downside is the lack of a control. You would expect a lot of improvement in PTSD symptoms over six sessions anyway.
