This evening, Lynn welcomes Dr. Benjamin Toll. Dr. Toll is an Assistant Professor of Psychiatry at Yale School of Medicine and he joins us this evening for a conversation about smoking cessation. Here is Lynn Wilson.
Wilson
Let's start off by having you describe for us what smoking
cessation is.
Toll
We typically think of quitting smoking as being a current smoker, a
person who smokes 100 cigarettes or more that is currently smoking
daily or perhaps some days per week. For that person trying
to quit, generally the quitting treatment is through both drug
treatment and counseling treatment, meaning that we do some kind of
pharmacotherapy, plus counseling. Counseling is typically
four to eight sessions spread over a month, to three months, and we
hope for people to be quitting for a year plus.
Wilson
And by pharmacotherapy you mean medications?
Toll
Yes. Our treatment is completely evidence-based, meaning that
we use drugs that are approved by the FDA. Those are the
current first-line treatments, any of the NRTs, which is a kind of
nicotine-type drug, so the patch, gum, or lozenge, or bupropion
which has a trade name of Zyban, or the trade name Chantix for
varenicline.
Wilson
How did you become interested in this field? Obviously, it
is extremely important but there are not too many specialists that
do this.
Toll
My path was not exactly a straight path. Truth be told, I was
a junior in college and I was a psych major at Cornell. I did a
psychology internship in Sydney Australia and it was a very fun
time. The internship was through a drug and alcohol counseling
clinic, and so I got interested in treating alcohol problems, which
in my opinion are very interesting. Then when I got to my
graduate training, the problem was that it is really tough for a
graduate student to do alcohol research at my location because of
IRB issues and it just seemed a lot more challenging. My mentors at
that time were doing smoking research and said, you know Ben, I
think this would be a lot more straightforward and still really
interesting, and so I started to do smoking research, and by the
way, I am still doing smoking and alcohol research, but my current
focus is smoking research. I have got a current QuitLine study
looking at providing counseling to risky drinkers that smoke to try
to get them to improve their quit smoking outcomes.
Wilson
How big of a problem is smoking in the United States and how many
smokers are there currently?
Toll
There are currently about 47 million smokers in this country.
The statistic in 1965 was about 42%
4:27 into mp3 file
http://yalecancercenter.org/podcast/feb0611-cancer-answers-toll.mp3
or so of this country smoked. That rate has fallen to around
21%. So that is good. The problem is that in the past
few years, the rate has plateaued. The largest survey showed
in 2004 a rate of 20.9%, that rate in 2008 was 20.6%. So the
problem is still currently there and it is possible that we are
getting to a very tough population of smokers for whom it is
tougher to quit.
Wilson
What is the average age of somebody when they begin to smoke?
Toll
It is hard to give a specific age. Typically, we talk about a
range. The statistic that most people quote is from the age
of 12 to 17, about 3500 youths' smoke their first cigarette, and
about 850 become daily smokers. Then what drives that rate, or what
is correlated with smoking for youth, typically, unfortunately, is
going to be low SES, a peer group who smokes or perhaps brothers
and sisters, parents and guardians smoking, and certainly access is
a big issue. So if you are in an urban area and there are a
lot of package stores that you live right near. There are a
number of reasons that drive you to smoking.
Wilson
We hear a lot about smoking being related to lung cancer, but what
other cancers are related to smoking and tell us a little bit about
the diseases that are noncancerous that smoking can cause or
induce.
Toll
We know that smoking is related to at least 15 types of cancers
including sinuses, stomach, bladder, larynx, lip, and pancreas, but
the important thing for cancer patients, sort of what we say to
cancer patients, is that it is very important to quit smoking; it
is going to improve the treatment effectiveness of cancer
treatment, and that means cancer surgery, chemotherapy or radiation
therapy, it is going to cut down risk for future second primary
tumors and it is going to improve longevity, so those are a bunch
of very important reasons for cancer patients to quit
smoking. To get to the second part of your question, smoking
is also correlated with stroke, cardiac problems, chronic
bronchitis, emphysema, and ulcers.
Wilson
In terms of your experience, in your research and expertise, when
someone has been a long-time smoker, they are smoking a pack or two
a day, what is the general success rate for someone who is ready to
try their hardest to stop smoking? If you had 100 people that
signed up for a program, generally, what is the percentage of those
100 people that perhaps a year later may no longer be smoking?
Toll
It depends on the treatment intervention. Keep in mind, for
me treating smokers, we always want to pair drug therapy with
counseling therapy. There are certain people that do not want
to do one or the other. Some people just want drugs and some
people just want counseling, but we strongly encourage people to do
both. Quit rates are highest when doing both.
Typically, we give patch plus gum or patch plus lozenge, or
Chantix. They are the two primary drug treatments that I like
to use, and a counseling protocol for both is around two to three
months, and that is weekly counseling. It is typically 30 to
45 minutes of counseling. In the counseling we deal with
coping
9:45 into mp3 file
http://yalecancercenter.org/podcast/feb0611-cancer-answers-toll.mp3
skills for cravings, trying to increase pleasant activities,
talking about pros and cons of quitting, and talking about peer
support on these types of coping skills. So patch plus
lozenge will give you a quit rate at eight weeks about 50%, at six
months about 40%. With Chantix, we are looking at a 12-week
quit rate of about 44% and they report 12-month quit rates of
around 22% or so.
Wilson
I am sure something our listeners are interested in is how they
can contact your service if they are interested in smoking
cessation?
Toll
Right now we are launching a quit smoking service through Smilow
Cancer Hospital. We are treating Smilow patients and our goal
is to increase the program to be open to the general public.
At this time, it is including Smilow Cancer Hospital patients and
in the future we will be expanding to the general public.
Wilson
That is terrific! What are some of the biggest obstacles you
face in trying to get folks to quit smoking?
Toll
The truth is, people love smoking. So our primary obstacle is
usually motivation. People have strong, negative, and
positive feelings about smoking. Every smoker that you talk
to says, "I know I should quit." The problem is that not
everyone says "I want to quit" or "I can quit." So increasing
motivation and confidence is a big issue. Why? Smoking
is very satisfying. People are smoking because it feels
great. It is a very strong drug. It is a very strong
habit. People that have smoked for 20 years, a pack per day,
have literally been smoking millions of times. It is a strong habit
and why is it so satisfying? The tobacco companies, there is
a lot of evidence that shows that the companies have chemically
altered their product to make is more satisfying, to make it a
stronger drug. Our primary problem is generally
motivation.
Wilson
What are some of the factors that you have identified that may
suggest someone might have an easier time with cessation? Is
it the number of cigarettes they are currently smoking or the
number of years they have been smoking, their family support
system? What sort of factors are you thinking about that when
someone becomes your patient you might say, this person might be
someone that I might have a better chance of helping because of
factors x, y, z.
Toll
Typically we think of more dependent patients as being
tougher. We measure dependence through two primary
things. One is the quantity of smoking. A greater
quantity is generally more dependent, and two is time to their
first cigarette. The quicker that you light up, the more
dependent you are. If a person tells me that they smoke
within five minutes of waking up, and there are a two-pack-per-day
smoker, I know right away that they are going to be a tougher
patient and that they are going to need more care, perhaps, longer
pharmacotherapy, longer drug treatment, perhaps additional or
longer counseling.
Wilson
We are going to take a short break for a medical minute.
Please stay tuned to learn more information about smoking cessation
with Dr. Benjamin Toll.

Wilson
Welcome back to Yale Cancer Center Answers. This is Dr. Lynn
Wilson. I am joined this evening by Dr. Benjamin Toll and we
are discussing smoking cessation. Ben, the first part of the
show was extremely interesting and I have got some additional
questions for you. How do you think the image of smoking has
changed over the years? You mentioned a little bit about
cigarette manufacturers, things they were actually doing to the
cigarettes, marketing and advertising, talk to our listeners about
these factors, how have things changed? Obviously the tobacco
industry has a very strong advertising and marketing campaign
going.
Toll
In this country, it used to be that smoking was acceptable, in the
first half of the 1900s. It was not until the 1940s and 1950s
that there were studies that started to show that smoking is a
cause of lung cancer, but the scales did not really tip, in my
opinion, until about 1965, and that is when the big Surgeon
General's Report came out that said very clearly that smoking is
strongly related to lung cancer, and all these other things too,
and that was when the scales really started to tip towards people
seeing smoking as being negative. If you fast forward until
the late 1990s until now, smoking for better or worse is viewed as
a bit more stigmatized. If you are in California and you are
doing surveys, people will literally lie to you and tell you that
they do not smoke because it is so stigmatized. It is getting
to the point that our country is turning very smoke-free and
smoking is less of a positive image now. It used to be that
you had the Marlboro Man, big tough guy that was a smoker and was
really cool. More recently, there have been reports that
Marlboro Man got cancer and it is very negative, and there is a lot
less advertising about smoking. There is currently no
television advertising. There is still print advertising.
Wilson
And is it not allowed on television?
Toll
It is not allowed, yes.
Wilson
I see.

Toll
It is currently banned. A big change very recently is that
there are now going to be graphic warnings on packs. It used
to be, starting in 1965, there were these small text warnings that
were very clear and said things like, smoking causes lung
cancer. Now there are going to be big graphic warnings that
show teeth that are hollowed out, with gums that are blackened,
really graphic gruesome things, and they are pretty large
too. A big part of your pack will show a graphic warning that
says something like, "Smoking causes mouth decay", and in my
opinion, that is a really positive step. I have colleagues in
Canada that have shown that these graphic warnings are certainly
helpful for getting people to consider quitting and possibly to get
people to try quitting. My research about message framing
shows that it may be good to test also a gain-framed approach to
warnings, meaning that we have tested counseling treatments
comparing gain- and loss-framed statements. A gain-framed
statement is, if you quit smoking, you will save money. A
loss-framed statement is, if you continue smoking, you will lose
money. We are trying to enhance the positive aspects of
quitting smoking instead of trying to highlight the negative
aspects of continued smoking. There is currently interest in
people testing pack warnings that have positively framed
text. So, if you quit smoking, your risk of lung cancer is
greatly decreased, let's say.
Wilson
What is prospect theory?
Toll
A prospect theory is a transdisciplinary theory that was created by
two psychologists, Kahneman and Tversky. Dan Kahneman won the
Nobel Prize in 2002. It is a theory that states that if you
highlight the gains, or positive aspects, of an issue, people stay
away from risk, and if you highlight the cost or losses, people try
to seek risk. Now what does that mean? Let us take
gambling. If you go up to Foxwoods, a Connecticut casino, and
you are gambling on say blackjack, and you are gambling and you are
losing, and you have lost $1,000. Now you are down that
$1,000 and you are going to start making risky bets, trying to win
that money back. If you are playing blackjack and you have
won $1,000 and you are doing well, you are going to make more
conservative bets to try to keep that money. Prospect theory
is a very broad theory that spans things like gambling, politics,
and health. What we have shown for smoking, quitting smoking
is a prevention behavior, meaning that if you quit smoking, it
strongly cuts down your risk for problems like cancer, stroke,
cardiac problems, and chronic bronchitis. Prospect theory
would predict that gain-framed messages are more likely to promote
quitting smoking, and what we found in two clinical trials so far
is that that is true.
Wilson
You had mentioned QuitLines, can you give us more details about
your new system of smoking cessation?
Toll
QuitLines are a great system of helping people quit in our
country. In the early 1990s, around 1992, the first QuitLine
launched in California. After that it started to gain
traction. In 2004, a National Association came about for
QuitLines and currently across the whole country, there are free
phone numbers that you can call to help you quit smoking. And
so what are QuitLines? You call up and you will be engaged in
a brief interview where they will give you counseling.
Typically, it is one to perhaps eight sessions of counseling and it
is by phone. In many states,
23:48 into mp3 file
http://yalecancercenter.org/podcast/feb0611-cancer-answers-toll.mp3
including this state, certain people can get free
medications. I have worked very closely with the New York
State QuitLine. In that QuitLine, the typical treatment
regimen is that a person calls up and there is a 10-min counseling
interview where they ask you questions and they give you counseling
through the interview and if you are medically eligible, they will
send you a free two-week starter pack of drug therapy, patches
gums, or lozenges.
Wilson
And if someone does require medications for cessation, do
insurance companies typically pay for this?
Toll
It is really company by company. So the short answer is that
yes, a bunch of them do. It is not always covered though, and
unfortunately, the patient needs to call their company to find
out.
Wilson
You have developed a very specific expertise in this area Ben,
tell us about some of the studies that you have done, specifically
about some of your research and some of the findings that you have
made.
Toll
I started mentioning our message framing work. What we are
really excited about is a few things. Our first large study
through the QuitLine was this message framing study, where we
compared standard counseling plus a two-week starter pack of drug
therapy to gain-framed counseling, plus the starter pack of drug
therapy, and what we did was, we took the actual print matter from
the New York State QuitLine that was partially loss-framed and we
gain-framed it, meaning that there was a black lung in their
brochure, I took that out. They said that smoking causes
problems like lung cancer, cardiac problems, etc. I changed
that language to say quitting smoking will prevent problems like
lung cancer and cardiac problems, etc. Then what we did was
trained their counselors to provide a gain-framed counseling,
meaning that instead of talking about the problems caused by
continued smoking, their statements were about the kinds of
benefits from quitting smoking. So, a caller calls up and
says that they want to quit smoking. Counselor then says,
what benefits do you expect to get from quitting smoking? The
caller might say, I think that I am going to save money, I am going
to not get cancer and I will breathe easier. Counselor then
says, great, it sounds like you feel that you are going to not get
cancer, that you will save money, and that you will breathe easier.
Throughout the interview a bunch of these gain-framed statements
were brought back to the patient, personalized gain-framed
statements and canned gain-framed statements. What we showed
empirically was two things. Importantly, in QuitLine
research, there was, until now, no group trying to train QuitLine
counselors to a new counseling treatment. There have been a
lot of studies about varying the amount of medication, the length
of call, amount of calls, no one has trained counselors to
counseling content, and that is what we did. We are the first
group to prove empirically that you can both train and test new
counseling treatments through QuitLines, and that is one thing that
we are quite excited about. I mentioned that the gain-framed
group showed an improvement in quit rates too, and to get to our
new study, we are currently providing a study for QuitLine callers
who drink at risky levels, meaning that if you call up and we give
you a brief assessment about your drinking and you're drinking at
hazardous levels, we are currently testing standard smoking
counseling to a drinking counseling kind of intervention,
28:56 into mp3 file
http://yalecancercenter.org/podcast/feb0611-cancer-answers-toll.mp3
specifically trying to improve their quit smoking outcomes.
We are asking callers to cut down to quit their drinking, to help
them quit smoking.
