Every time you smell cigarette smoke you’re breathing it in and it’s doing you damage. Even if you can’t smell it, if you’re near a smoker, you’ll be inhaling tiny dangerous particles with every breath. If you are that smoker, you’re risking other people’s health as well as your own.

Some tobacco companies, and some smokers, still say that passive smoking isn’t a real problem, or that it’s a myth. That’s absolutely not true. All the best scientists and organisations agree that passive smoking is a very real problem and that many thousands of people in the UK die every year from smoking related diseases caused by passive smoking.

Smoking can also send out the wrong message to people who look up to you. Your younger brothers, sisters or cousins could easily think that if you smoke, smoking is ok. If they’ve seen you smoking, and they start, you’re partly to blame.

Those were just a few tasters – a handful of the many health risks associated with smoking. There are so many other things that can go wrong if you smoke. You can go blind, for example, or your teeth might fall out. You could get osteoporosis. That would make your bones so weak and brittle that your own bodyweight could snap them. Or Crohn’s disease, that’s chronic inflamed bowel.
