"Okay, so less than a dollar a smoke on the average."
Oh, usually significantly less! After all, a $10 tin would equal about .50/bowl. And even a $15 2oz tin would only come to .75/bowl.
Which is why I'm constantly amazed when folks complain about the prices of tinned tobacco. Taking the time of a smoke into consideration (30-45 minutes for a bowl, say), you can smoke the highest-quality tinned blends for much less cost than you can smoke even cheap cigars and cigarettes. And when you compare boutique pipe-tobacco blenders with boutique cigar makers, there's absolutely no comparison. Even if you paid $1/bowl for the pipe tobacco, you'd pay at least 1,500% more to have a comparable-quality cigar!
