I went to an 80 year old's birthday party recently and he has been smoking since WW2 or thereabouts. His advice - get a pipe and buy tobacco from a proper tobacconist. In that way he avoids all the chemical horrors of regular hand rolling tobacco. Normally this stuff has flavours in it, stuff to make it burn and stuff to keep it moist. The difference is huge.

My advice to the government is to ban adulterated tobacco products so only dry rolling tobacco is for sale. Then to apply a minimum age to buy tobacco with this age rising one year every other year. In a relatively short period of time tobacco will become as rare as pipe smoking is.
