Yeah pipes and pipe tobacco.
I tried pipes several times in my youth, as a cigarette smoker and didn't 'get it'.
I smoked cigs and mostly ryo on and off for years.
Finally, one day a year into retirement, I went and got a cob and a week or two later, after smoking crap I had on hand for ryo, I discovered this forum and the ytpc, and it was all downhill...
I've covered a lot of ground in three years, and it's been a life saver, truly, to have learned to absorb nicotine via my mucosa.
Here we not only exchange information about pipes and tobacco, we also validate our hobby by sharing our experiences and in some cases, expertise.
