Smokers are constantly told that quitting cigarettes is one of the best things they can do for their health, but many continue to do so.
The latest statistics show that more than a third of smokers (36.6%) tried to quit in the last 12 months.
But it's never as easy as just saying you're going to quit and then being done with it.
Quitting smoking can be extremely tough, but never fear, there is plenty of advice out there.
So with that in mind, we've drawn up the dos and don'ts of quitting smoking and listed some key bits of help:
What does smoking do to the body?
You'll look better as more oxygen gets into your skin, making it brighter, and your teeth will no longer get stained with tar.
Your longer-term risks of cancer, lung disease, heart disease and stroke will be significantly reduced, and:
Every time you smoke a cigarette, your body is flooded with thousands of chemicals, many of which are poisonous.
The day you stop, your body starts clearing itself of all those nasty toxins and the repair process begins.
Many people try to quit smoking with willpower alone, but it's much easier to go smoke-free with the right help. There are lots of support options available, try a combination that works for you.
"There's some confusion and misleading information about vaping, which can make it difficult to work out what's true or not.
"Nicotine vaping is substantially less harmful than smoking. It's also one of the most effective tools for quitting smoking.
"Vaping is not recommended for non-smokers and young people because it is not completely harmless.
"The routines and rituals of smoking can be hard to stop, so vaping can help you gradually let go of these while immediately reducing the health risks of smoking cigarettes."
Stop smoking aids
Stop-smoking treatments help with managing nicotine cravings and other tobacco withdrawal symptoms. They also boost your chances of successfully quitting, especially if you get expert support from your local Stop Smoking Service.
If you have tried to stop smoking aids before, it's worth trying again because you may need to try a few to find what's right for you.

Emeritus Professor of Behaviour Scientist at UCL Professor Robert West said: "What is really interesting is just how much of an impact self-efficacy, that sense of self-belief and confidence, has on quitting success.
"That confidence is something we can help to influence. It really does show the power of the mind - self-belief when combined with other quitting aids such as vapes or NRT, effectively equip people in giving up.
"What people considering quitting this Stoptober should also bear in mind is that even if you've tried to quit before and not managed it, that doesn't mean it won't work this time. You will have learnt something from your previous attempts: think of each quit attempt as a stepping stone to becoming smoke-free for life."
