I just lit a cigarette and let it burn out, so all i have left is a pile of ash. This ash weighs far less that the cigarette did, so where has the rest of the weight gone?

Are you sure the ash weighs less than the cigarette?, I seem to recall burning magnesium at school 60 years ago and finding a weight increase.
Of course with a cigarette quite a lot of materiel goes off in the form of smoke.

what about the tar and nicotine that goes into your lungs surely they weigh something.

As does the major stuff, carbon, of the plant. It is combusted into carbon monoxide and dioxide. The ash is the incombustible part.

I forgot -

Paul, what does cigarette ash have to do with the "Physics, Astronomy, Cosmology" section? Are we considering tobacco to be from an alien source???????

The ash is clearly the dephlogisticated cigarette - although phlogiston is supposed to be weightless, but clearly you have proved them wrong ;)

Well, yes - America is an alien place ;)

I have to say they are well organised in California with respect to visits from outer space, although there are no special rules even if you have travelled light years to get there - at the customs post coming in from Mexico (Tijuana) the sign says "All Aliens must show Identification".

Bit thoughtless of them to tell you only at the last minute - If I'd arrived from HD189733b, 60 light years away, I'd be really quite miffed if they made me go back and get my passport.

A fair bit of the weight is lost as water vapour too.
