See how tobacco changes people. Take a tour around and in the body by pressing the plus and minus symbols. Move the scroll button in the middle of the page to compare the differences between smokers and non-smokers.

## Smoker

The smoker's skin looks unhealthy, because the chemicals in cigarette smoke makes the skin's elastic fibers snap more easily. This causes the skin to lose its elasticity. A weary face is not a popular one: out of the 100 most popular profile pictures in a dating service only two were pictures of smokers.

## Non-smoker

The non-smoker's face looks healthy, because there are no skin-weakening substances circulating in his blood. Not smoking has the same effect as cosmetics: the skin stays healthy and attractive.

## Smoker

Smokers are more likely to get spots. Smoking weakens the skin’s blood circulation, which increases the risk of infections. Smokers' acne is also more difficult than usual.

## Non-smoker

The non-smoker's skin remains spotless, because his blood circulation does what it's supposed to do. It helps avoid infections and makes it easier to get rid of spots.

## Smoker

Wrinkles come sooner for smokers. Smoking decreases the skin’s collagen and elastin levels – both familiar from tv ads – which harms its elasticity and firmness. It wrinkles.

## Non-smoker

Non-smokers have five times less wrinkles compared to smokers who have smoked a pack a day for 25 years, according to research.

## Smoker

A yellow smile reveals the smoker. The discolouration is caused by tar getting stuck in the cracks of the tooth enamel.

## Non-smoker

If you don’t smoke you get less tartar which is really uncomfortable to remove. Non-smokers are also four times less likely to get oral cancer.

## Smoker

Smokers have bad breath. As many as 20 per cent of people have ended relationships because of smoking. Halitosis isn't appealing.

## Non-smoker

The non-smoker's breath doesn't smell of tar, and there's no green phlegm being pushed out by a smoker's cough. In Burn magazine's interviews several celebrities revealed they prefer kissing non-smokers.

## Smoker

A yellow smile reveals the smoker. The discolouration is caused by tar getting stuck in the cracks of tooth enamel. Smoking and using snuff can also cause oral cancer.

## Non-smoker

If you don’t smoke you get less tartar which is really uncomfortable to remove. Non-smokers are also four times less likely to get oral cancer.

## Smoker

Smokers have brittle hair, and they are more likely to go bald and grey than others. Chemicals from tobacco gather in the hair, and cause hairs to break off before they are fully grown.

## Non-smoker

Non-smokers usually get to enjoy the colour and quantity of their hair longer than smokers.

## Smoker

The smoker is more stressed than the non-smoker. Side effects of smoking cause constant nervousness. It’s a myth that cigarettes calm you down.

## Non-smoker

The non-smoker is not constantly glancing at his watch, tapping the table, or wondering when he can smoke the next time. He focuses on living in the moment.

## Smoker

Dear Smoker, we're sorry to inform you that according to nail fashion experts, nicotine yellow is not this season's colour.

## Non-smoker

The non-smokers decide what colour their nails are – natural or polished but never yellowed by nicotine.

## Smoker

Smoking damages the lungs and makes breathing more difficult. The smoker can't run or dive as long as others. When old age hits, there is also the risk of chronic obstructive lung disease. It feels like breathing with your hands in front of your mouth and nose.

## Non-smoker

There's less phlegm in the non-smoker’s lungs and a smaller infection risk. The non-smoker can climb up the stairs of an apartment block, even when a little older. The smoker will be breathing heavily before getting even halfway.

## Smoker

The unpleasant dark lump there is lung cancer. Smoking causes nine out of ten lung cancer cases. The risk of getting lung cancer increases the earlier you start to smoke, the longer you smoke and the more you smoke.

## Non-smoker

Congratulations, non-smoker! The risk of you getting lung cancer is small.

## Smoker

That nasty hole is a peptic ulcer. The nicotine in cigarettes weakens the stomach's ability to fight the Helicobacter pylori, and causes the ulcer.

## Non-smoker

No nasty surprises here, because the non-smoker's stomach is safe from nicotine. That's why its immunity remains strong against, for example, the Helicobacter pylori that causes peptic ulcers.

## Smoker

The image shows a blood clot, which can lead to sudden death. For smokers the risk of a blood clot is double compared to non-smokers.

## Non-smoker

Not smoking helps to keep the blood vessels healthy.

## Smoker

Smoking weakens the blood flow to the penis, which counts for smokers being twice as likely to have erectile problems. The number of intercourses is also half compared to non-smokers.

## Non-smoker

The blood really flows in the non-smoker's veins. You could even say that not smoking is the cheapest drug against erection problems. Half of impotence cases are caused by problems in blood circulation and the nervous system.

## Smoker

The smoker's sperm density is significantly less compared to the non-smokers. The toxins from cigarettes decrease the concentration and mobility of sperm cells in semen and harm the cells' structure.

## Non-smoker

Non-smokers have more sperm cells. The semen stays healthy, because the chemicals in tobacco don't get the chance to hinder the movement or decrease the number of sperm cells.
