Hi NIghtlight, thanks regarding the tar explanation. yep, guilty of the youthful foolishness! That is true. How I managed to do that is beyond me, but not surprising due to age and stupidity.

However, sadly i didn't get any warning signs until it had gone past that point. Once I felt odd, though I stopped, it was kind of too late.

So yes nicotine poisoning it was. Not fun. I reckon its right to do things in moderation. Even if you believe smoking is great, if it's excessive as with anything, there is an element of unhealthiness about that as well. Just my opinion and what suits one person may not suit another. People do have a right to be for or against it.

Nicky.
