How to quit smoking, according to scientists

Go "cold turkey," or pick a "quit date."

One way to quit is, of course, to stop smoking entirely. This can pose some challenges since it's easy to relapse, but it can work well if you have a plan in place. Fiore likes to refer to it instead of as going "cold turkey," but rather as picking a "quit date."

Whether you're stopping abruptly, or more gradually cutting back, Fiore said it's important to stick to a schedule. It's easy to have one stressful day, or even a celebratory occasion and lapse back into old smoking habits.

Put money on the line.

A number of studies have found that giving people money can help people quit. One study of roughly 2,500 smokers paid out as much as $800 if they were able to be smoke-free for six months. After the results were published in 2015, CVS Health, which had conducted the original study, decided to roll out the program to all of its employees.

Exercise.

According to SmokeFree.gov, exercise can reduce your urge to smoke and withdrawal symptoms decrease during exercise and for almost an hour after you're done. That's especially the case with aerobic exercise, like running, swimming, and cycling.

Fiore said exercising can also be a good coping mechanism, and can help people keep off the weight they sometimes gain when they quit smoking.

Practice mindfulness.

While it's still relatively new, there is some evidence that mindfulness meditation could be a useful tool to help people quit smoking. A small study from 2013 found that the 15 people who practiced "Integrative Body-Mind Training," a form of mindfulness meditation, were able to cut down their smoking habits by 60%, while the group that was just told to relax didn't have any reduction.

Fiore said the best way to think about mindfulness meditation, yoga, etc. are as add-ons to a quitting plan that involves medication and counseling.

Use a texting program.

There are hundreds out there, but Fiore said the one he'd recommend are those that have evidence to support them, in particular the one the NIH has, called SmokeFreeTXT.

A study of a UK texting program found that the texts that provided motivational messages and tips on how to quit improved smoking cessation rates over a six-month period compared to a control group that received texts unrelated to smoking.

Go to counseling.

Fiore said that in addition to using medication, it's helpful to get counseling— either through conversations with loved ones or friends, or with a professional.

Take smoking-cessation medication.

There are other non-nicotine approaches to quitting that you can use. Fiore highlighted varenicline, otherwise known as Chantix, as one possible approach during the first few months you're quitting. The drug Zyban is another option. The two work to block receptors, keeping the nicotine from activating the brain.

Consider nicotine replacement therapy, like patches or gum.

Fiore said he recommends using medication as a component of your plan to quit smoking.

According to the NIH, nicotine replacement therapies, such as patches or gums, help alleviate some of the symptoms of withdrawal by giving you small amounts of nicotine. Nicotine is an addictive substance that's found in tobacco.

Get prepared before you stop smoking.

First thing's first: it's important to keep in mind that there's no one foolproof way to quit smoking. "Quitting smoking is hard work," Fiore said. But you can combine a few tactics that can make the process easier.

If you've had a smoking habit for a while, quitting right away can be a nearly impossible task. Ahead of quitting, the National Institutes of Health's website SmokeFree.gov recommends having a plan. That includes laying out why you want to quit, whether it's for your health or your family. It could also mean letting your friends and family know you're planning to quit, and identifying possible triggers that could cause you to start smoking again.
