Smuggled cigarettes more dangerious than normal cigarettes.

Cigarettes smuggled into Britain may be more dangerious because not only because they may be fake,but because they may contain arsensic and cadium.

Counterfeit cigarettes contained between 2 and 6 times as much of these chemicals.

Smoking 20 of these is the same as smoking 100 real ones.

Problem is most serious in London.
