Is an occasional smoker safe from health concerns? Well, it’s being believed that though there is significant difference if a person is smoking 20-a-day or 20-a-month, smoking does produce its negative results in some or the other way.

If an expert on smoking at University College London, Professor Robert West is to be heard, occasional smokers are equally addicted as nearly 80% of them find it difficult to leave this addiction, irrespective of number of cigarettes they smoke.

Though nicotine addiction is very much known to all, smoking under the effect of a stimulant factor be it at a particular time or under particular situation is in itself another form of addiction.

Though transition from daily smoking to occasional is a daunting task to even think of, it can be done with rock solid resilience.

There is no second thought about attached health concerns; Professor West keeps cancer and heart diseases among the scariest of all.

"The excess risk of cancer for a daily smoker is 15-fold higher than for a non-smoker”, added Professor West.

It’s believed that with the way young people are smoking, it won’t be too far to prove what Sir Richard Peto, Britain's foremost expert on smoking, said that every smoker would join 20-a-day smokers group in the end.
