I thought so. I guess there's a smoke involved as well.
You mentioned behavioural cognitive therapy. I don't know exactly what that is, but I'm going to take a stab at it, and you tell me how right or wrong I am.
I'm guessing that is where somebody suffering post-traumatic stress disorder exhibits symptoms. Maybe they don't want to be around things that trigger a memory of the events, or they have difficulty sleeping, etc. What you do—this is my guess—with behavioural cognitive therapy is educate them to the fact that those symptoms are related to PTSD, making them aware of it. That's my guess. I would like to get your sense of what it is and get an explanation.
