It's funny you said that, unhappydaze. I found quitting smoking threw me into depression. I am an ecig user and I would never consider using it in anyone's office, home, car, or personal space without asking. But in my office, sure, just not while conducting business with a client. Your breaks should be taken between clients, in my opinion.

However, I've never found myself so relaxed while vaping that I've melded into the furniture and forgotten my boundaries. Nicotine is not a mind-altering substance for me.

There are personal vaporizers for use with other substances, which is why I posed my question way up thread. What exactly was the therapist vaping?

And why he felt the need to do so in session, instead of between sessions? Every addiction has a hold on the addict, but to the extent that you must indulge right this moment? I'm more concerned about this therapists loss of boundaries than what behavior he exhibited.
