Well, not quite interesting emerged even after I dug a bit about it. First of all, there would still be tobacco and users. Man has been innovative in employing all natural things into his use; no matter it is wild or mild, tobacco is one amongst them. Think about alcohol for a while, how did man know about it, alcohol didn't even exist in its consumable form, not even today, and man learnt distillation to get alcohol; but tobacco was available naturally, processed or not, smoking is only a manifestation of its different uses.

OK, but can you think of a world without cigarettes even in the present day? What would have happened to all those smokers if cigarettes were to be banished from, say, USA? Manufacturers of Marlboro, Camel, Winston, Virginia Slims, Salem, Menthol, lm and many brands will not loose their sleep for long over this decision they will however shift to neighboring or greener countries to continue manufacturing. Just a slap of higher tax on cigarettes has partly done this and the discount cigarettes we see are sold as cheap cigarettes online are surrogate methods of marketing their produce, albeit at cheaper prices. To me, this means, that hardcore smokers can't stand the shortage of cigarettes, let alone no cigarettes at all; whereas now, they must be pretty comfortable smoking the same old cigarettes, albeit at discount prices.

Well, this brings us back to the original question, how would be the world, had there been no cigarettes at all. Plainly, there would be other forms of tobacco consumption, more likely in unprocessed and crude forms; there would be more harms than goods. Haven't we seen the Asians villagers suffering from mouth cancers because of tobacco chewing habits in addition to risking all other gangers that cigarette smokers risk?

This is no attempt to hail cigarettes but the ingenious man would have found some alternative, just like the present cheap online Marlboro, discount cigarettes sold at sale.
