Never been a cigarette smoker (though like most of us will have tried the odd cigarette).
Have tried snuff, it is disgusting and gives you black bogies! I tried chewing tobacco in Virginia, that was quite nice. Paan with tobacco in India was quite intense.
As a non smoker, I have always found nicotine to be a really strong drug, and so strong that it can be unpleasant. For example if I were to properly smoke a whole cigarette I would certainly throw up!
I like cigars (proper Cubans), and smoke them occasionally, but again there is a risk of it being too much for me, and I can't handle a really long cigar.
It has always been an issue with spliffs for me, I can't handle the tobacco. If I was rolling myself it will always be pure.
