This has been known for a long time. The SA article is amazingly disingenuous. It fails to mention the extent to which the problems addressed by nicotine might be side-effects of the medications prescribed to schizophrenics. It conflates "schizophrenic patients" (ie, those likely to be, or to have been, on anti-psychotics) with schizophrenics. These are two different groups. What's the rate of smoking among people newly diagnosed with schizophrenia? What's the rate among those on mood stabilizers and anti-psychotic medications who are not also diagnosed with schizophrenia? What's the rate among those who have spent substantial time in the hospitals and day-use facilities that many schizophrenics are forced to spend time in? What's the rate among the homeless population?

Cigarettes aiding concentration in schizophrenics is old news. I've read advice that schizophrenics use nicotine patches and the like to get the beneficial effects while avoiding the negative effects of smoking.

Anecdotally, yes, schizophrenics tend to be smokers, and very heavy smokers. I was surprised recently when one of my schizophrenic clients quit smoking without severe problems. Prior to that he smoked about 7 packs per day. He rolled his own, but with recent tax increases, he couldn't afford it anymore and up and quit. I haven't noticed any cognitive degeneration since he quit, but he's a pretty severe case to start with.

Schizophrenia is particularly interesting to me because it is so distinct and so consistent compared to many other forms of mental illness. When I sit down to talk to someone knew, I know immediately when they have schizophrenia. The diagnosis is so much more clear-cut than many others.

In a similar vein a number of people have noticed that individuals under the influence of datura constantly mimic smoking cigarettes.

The discussion centered around whether or not cigarettes contained a certain kind of agonist and that the mimicry was actually the brain trying to prompt the user to smoke as a method of combating the poisoning.

I also feel the need to point out that only the most desperate and stupid of fools tries datura.

After starting antidepressants a few months ago, I was overcome with an incredibly powerful urge to smoke. I had quit 18 years ago, and was never a heavy smoker - maybe a pack or two a week.

I was surprised to discover that I respond differently to the cigs than before. They used to be just a little pick me up. Now they are incredibly powerful mood lifters. If I go a few hours between cigs, sometimes the next one gives me an incredible rush, something very close to a two minute long orgasm. Really.

I know I shouldn't smoke...but daaamn.

Dima thinks when healthy subjects see the illusion, which is somewhat ambiguous, their brains strengthen this connection such that what they expect ¡ª a normal face ¡ª becomes more influential, overpowering the actual, though unlikely, visual information. Schizophrenia patients, meanwhile, may be unable to modulate this pathway, accepting the concave face as reality.

So schizophrenics see what's actually there.

I have to say I sat here and played that mask video two and a half times before I gave up trying to see it correctly.

I've noticed that if I watch the Chaplin mask video, and pay attention to the inside bottom part of where it is attached to the post I can orient my mind to the mask's rotation and prevent my brain from interpreting it as convex at the moment of transition, and then if I follow the line of the mask up into the nose to orient my mind just after the moment of transition I can see the mask as concave all through the rest of that pass. But in the next pass I still get the convex face illusion if I don't do the same thing, and I can't recover, either, by looking down towards the attached area and then back up towards the nose.

Dunno if this is an exception that works for other normal people, or I'm just borderline.

After visiting a friend in a public mental health facility, I wouldn't be all that surprised if 85% of institutionalized mental health patients pick up smoking habits, regardless of their illness.

I'd actually be interested in knowing how that 85% figure compares before and after the past 25 years of spending cuts in public mental health care that ensure a lot of people who need treatment will never be inside an institution, bored out of their wits, with nothing to do all day but watch TV, smoke, play cards, smoke, do crafts, smoke, read and smoke.

A few years ago, I was involved in some work that interviewed people with psychotic disorders who had been hospitalized about their cannabis use -- trying to get at why, given that it may be indicated in relapses and exacerbating their condition, people still continued to smoke it.

Their responses were really interesting and almost all had to do with ameliorating either the effects/side effects of the medication or their illness. People said things like 'it makes the meds tolerable', and 'I still hear voices, but the things they are saying aren't quite so obnoxious when I've been smoking weed as they are when I don't.'

Speaking as someone who used to smoke who is ADD, it can help a great deal with anxiety due to social situations (which is something of a side-effect of being unfocused, that you're getting far too much input at once and can't process all of it). One of my major problems was social anxiety, and smoking helped with that a lot, but I quit even before I was diagnosed ADD. A combination of sugar and caffeine really helped, as in a typical sugary soda, but I had to quit sugar, too, and caffeine by itself never worked very well. Adderall helps more, though, dramatically. The stress which came to the surface after quitting smoking never quite left me until I started getting treatment for ADD with Adderall.

Agree the article is disingenuous, you'd have to have put your head under a rock not to be aware of this. It's a Bad Thing, insofar as schizophrenia does not preclude intelligence, so a normally intelligent schizophrenic person may well be aware of the deleterious effects of smoking and feel bad as a result, mentally and/or physically.

An inexpensive and worthy use for a grant of some kind would be to buy a bulk supply of electronic cigarettes and see if they met schizophrenics' demand for nicotine doses while possibly improving their overall health. I've found them very helpful in that regard. (I'm not affiliated with any company that makes or sells these products.)

A multi-pack/day smoking habit is so hard on the body that I think it's cruel not to investigate this; short-term clarity for mental patients should not have to come at the likely cost of serious heart & lung disease. I doubt these substitutes are entirely risk-free but when the alternative is heavy smoking (vs not starting in the first place), I don't see how it could possibly make things worse.

Aren't a high percentage of people with schizophrenia homeless or institutionalized, either in a mental hospital or prison? It's been my impression that cigarette smoking is one of the few luxuries/relaxants people get in those settings, and that it's the norm for prisons and institutions to at least allow smoking in some situations (ie outside, in a smoking lounge, etc).

I suspect it's probably 40% culture (everyone they're with smokes, and smoking is a privilege, so it's normal and considered a reward) and 60% self medication (it relieves stress and symptoms).

Also, the inside of the mask totally looked like a face was sticking out, so I think I'm normal. That's a relief, and it's kind of freaky. I was expecting it to be a bit like that left-brain/right-brain ballerina animation that floated around the net, where you can easily force yourself to see it either way, but my vision was certain there was a face sticking out. It seems like schizophrenia is definitely going against some deep mechanisms in the brain to overcome that.

Schizophrenia, apart from the trauma and heartbreak, is fascinating in that you can see how often science has taken a swing and a miss at it. Lithium, ECT, and so forth. Other kinds of patients benefit from these discoveries, but not schizophrenics. The disease (if it is just one disease) seems like the Cantor Dust of mental illness, the ever-reducing, but still present, remainder after we remove everything else.

I think the hollow mask illusion is not actually an illusion. The image of the inside of the mask clearly and objectively is an accurate rendering of a lit face. It's not as if our brains are fooling us into thinking that looks like a face. That really does just look like a face. e.g. if you painted the outside surface the same color as the inside, and took images of the outside and inside surfaces in the same orientation and then put the images side by side, they will look almost the same. So no illusion is involved.

I think it basically must be just a geometrical fact that the lit inside surface of a hollow mask resembles closely the lit outside surface.

Though, I suppose it's possible that the inside surface has subtly "unnatural" lighting, which we with normal brains ignore more easily than schizophrenics. Still, covering bits of the image up with my hands, it doesn't seem unnaturally lit.

I dont buy the whole "there's nothing else to do" argument. Why smoking? Why not munching on Cool Ranch doritos or playing checkers? Or writing angry letters to the editor?

When I worked at a mental institution there were regular smoke breaks--I want to say hourly, but I don't exactly recall the schedule--that were built in to the day to day life. Everyone was in the smoke room for those. It was one of the ways that the inmates patients were given a structured day, which is very important for a number of reasons, not least among them that it makes it easier for the guards staff to manage them. It also gave some patients incentive to behave and take their meds; if they were good, they would eventually be able to go outside for their smoke breaks.

When you look at the people that were most likely to be in this hospital on a regular basis, you are basically talking about the bi-polar and schizophrenics folks--their illnesses tend to promote a real rollercoaster-like experience of life. Thusly, they were most accustomed to the routines of the institution, and I'm sure this affected their lives outside the hospital environment too.

Obviously this is just anecdotal, but I would be surprised if similar structures weren't practiced all over the U.S. (Texas being the exception, I guess) and even the rest of the world, smoking included.

Where are the People with Schizophrenia?

I think these statistics are a bit misleading--at least on their own--because they don't address the fact that schizophrenics (and other mentally ill) move in and out of various types of living situations and institutions throughout their lives. Things can shift for them quite rapidly.
