Many years ago (late '70s) during my first trips to the psych ward, we could smoke right there in the hospital. We could not have matches, of course, but there was a glow lighter on the wall. Around the time when smoking was later being banned in hospitals, public (aka government) buildings and so on, I read an article by a psychiatrist saying he believed smoking should be available for psych patients...and I have remained in agreement ever since. I do not know how or why it makes a difference, but I am just not my best "me" without the nicotine. I no longer smoke even close to three packs per day and I now make my own by injecting finer-cut pipe tobacco into pre-made tubes with filters, but I have been smoking tobacco for 40 years with no ill effect ever.
