Additive free is another good thing to look out for as you just get the tobacco not all the chemicals normally put in it you can get 'American Spirit' additive free tobacco in most places now it tastes very similar to homegrown.
I'm going to give them a try Baccyman, thank you for the tip

It's now become available in Morrisons, Tesco and Asda - I've smoked it since running out of my usual when on holiday in Amsterdam a couple of years ago. I asked for something mild and have not changed brands since as it's great. Much less 'smoker's cough' too. No nasty bitter taste on the lips either.
