Its a bit long but I hope it can be of some help. So here goes:-
Dr. Oz says the hardest thing about getting the 45 million Americans who smoke to quit is that they already know how bad smoking is for them—every pack actually tells a smoker about the dangers of premature aging, disease and death. "They seem like very rational people, right? They find a way to work, they get up in the morning, they can do all kinds of things. Yet despite being so rational, they keep trying to kill themselves," Dr. Oz says. "This is an effort for us to understand the biology of addiction."
Smokers continue to smoke not because of a lack of willpower, Dr. Oz says, but because of fear. "People are scared of what's going to happen," he says. "First of all, if I do it and I fail, I may be less worthy. And if I do it and succeed, am I going to be normal?"
One thing most people don't consider is how smoking affects their brain. After each puff, the nicotine reaches your brain within seconds. "They go to this part of the brain just above the ear … called the insula," Dr. Oz says. In the insula, the nicotine opens your brain's receptors and allows dopamine to flow in. "Dopamine is the ultimate addictive element in our body," he says. "When we have really good sex, dopamine comes out. When we have a double chocolate cheesecake, dopamine goes out. You do drugs, dopamine gets stimulated. … Cigarettes are as addictive as heroin.
At 29, Aubrey says she's smoked for more than half her life. Those years of smoking have already done some damage to her body, both inside and out. If she continues to smoke, the damage will only intensify.On the left is a computer model of what Aubrey could look like in 30 years if she stops smoking now. "You'll age a little bit," Dr. Oz says. "Your hair will change; your skin won't be quite as bouncy. But when you have four grandkids, you're still going to look pretty hot!"

Dr. Oz's call to all smokers is not beat yourself up because you haven't been able to stop smoking. Instead, arm yourself with tools so you'll never want a cigarette again.
In a telling exercise, Danielle adds up how much her smoking addiction has cost her—it's $22,428 over 14 years. "Wow, that's $22,428 that I've spent on cigarettes—$22,428 that I've spent on killing myself slowly," she says.
"I can give you all of the numbers—there are 250 toxic chemicals in cigarettes, and 50 can cause cancer. But you know all that stuff. That's why we don't want to spend a lot of time on this show telling you all the bad things that can happen," Dr. Oz says. "We want to dive into the root reasons of why we don't change."

Dr. Oz contrasts the healthy lungs with the damaged lungs of a smoker. Dr. Oz says this lung's moth-eaten appearance is evidence of emphysema, which is a condition of chronic obstructive pulmonary disease, or COPD. He also points out a lump that denotes lung cancer.
"People keep thinking it's about cancer. Cancer's the tip of the iceberg," he says. "Emphysema and COPD (Chronic obstructive pulmonary disease (COPD) and Emphysema is a chronic (long time) lung disease that get worse over time. " I googled to find out what it means.
Air taken into the lungs enters little tubes called alveoli. "They're like little bubble pops," Dr. Oz says. "As you smoke, you break down those barriers and you pop them. So you take these very nice grape-like structures and you turn them into these big sacs that no longer can exchange air with the outside world. Then when these coalesce and come together, they form these large blebs on the outside of the lung. … That air is not helping you because it can't get into your body and exchange with your blood. So literally as these blebs get larger, they push the normal lung away and you suffocate yourself."
To end the war, Dr. Seidman says you must "wave the white flag" and admit you need help in ending your addiction. "Smokers are not all the same. Some people can quit on their own and relatively easily, and some people will say it's the hardest thing they ever did. So they need the tools, and they need to make the effort," he says. "It's not just about the motivation—they have to make a commitment. They have to make the effort and need some guidance and outside help to be successful with it."
Once you've made the decision to live a smoke-free life, Dr. Oz, Dr. Seidman and Dr. Michael Roizen suggest following a four-step plan.
Step 1: Face the truth.
Take the quiz to determine what kind of smoker you are. Dr. Oz says learning how out of control you really are is an important realization. "Once you realize you're out of control, it helps you build your commitment and be willing to make the effort so you're not smoking at all," he says. "If you're smoking a little bit, that cigarette's going to make you want to have the next cigarette, and it's not going to go well."
(The test: How soon you wake up and need to smoke, do you sweat in the shower, how long cant you stand and need to break to smoke when you are in a meeting - this was an additional thing not covered in the oprah.com but what I copied down during the show time).
Step 2: Prepare yourself mentally and physically to quit smoking.
Dr. Oz says it's imperative to set a "quit date"—your first day of breathing free—between two weeks and a month ahead of time. During those last few weeks before your quit date, Dr. Oz says you should prepare yourself for a life without cigarettes.

In addition to preventing weight gain, Dr. Oz says walking has other benefits in your battle to breathe free. "If you've got a program that makes sense for you, and you're feeding your brain the right nutrients … you'll lose weight, and you'll be alert and ready to make these difficult moves like stopping cigarettes.
Step 3: Visit your doctor, find support and prepare for your first smoke-free day.
Before your quit date, Dr. Oz says you should talk to your doctor about the different medical options that can help you remain smoke-free. You can ask your doctor about several medications and aids.
Chantix, a new drug (block nicotine) and Wellbutrin were mentioned in the show but not stated again in the Oprah.com. They also did mention about the side effect such as nausea, fever, migraine and a few other effects but I forgot to write down.
Step 4: Protect yourself against a relapse.
So you've taken all the steps, your quit date has passed and you're breathing free—but you feel like having just one more cigarette. What now?
Turn to your support system. Whether you and a buddy decide to quit together or you find a support group, you should have someone to turn to when the cravings rear their ugly head.

When you're really in a crunch, Dr. Oz says you should also have some last-ditch escape mechanisms to steer your focus away from cigarettes. "It can range from other things to put in your mouth, like cinnamon sticks or tea. File your nails," he says. "Do something that distracts you at those times of crisis."
Aside from physical symptoms, which usually are temporary, Dr. Seidman says you must deal with the emotional issues that come with quitting. "Sometimes there's other things hiding behind the smoke," he says. "You might have problems with your mood or anger or other things like that. And if it doesn't get better, it's important to realize that whatever's wrong with you, smoking is not the best medicine for you."
