Man, I've been smoking 3.5 years and I can feel the damage, nothing major at this point but a reduction nonetheless. I wana quit as soon as I can but I suppose if you hit past the 20 year milestone you may as well continue at that point, as far as health is concerned. Then again, I'm a bigger fool for starting to smoke in this day and age you could argue, though one could counter that anyone is succeptible to becoming a smoker, given the insidious and subtle nature of the addiction! I'm just glad I've read Allen Carr's 'Easy Way to Quit Smoking' whilst my addicition was still rather infantile/in it's early years, and know that, using that insight, knowledge and understanding about smoking/nicotine addiction, coupled with knowing myself/my strength, resources, capacity etc, I'll be able to quit sooner rather than later.
I still enjoy Golden Virginia roll-ups, however.

And though I don't know anywhere where I can get my hands on em in the UK/over the counter- so it might just of been a one shot deal (any Frank Zappa fans?)!-, I have recently enjoyed smoking my way through a sleeve of Camel Full Flavours...
