That's going to be tricky as M&P use TA (
tobacco absolutes) and TE (
tobacco extract, a sister to
tobacco absolute). Now, that doesn't mean that the liquids taste "too ashy," but there will be some of that. However, I think M&P have some very interesting tobacco liquids. I would say start out with a small bottle of Tobacco Haze and maybe Tobacco Dulce. Give those some steeping time of course, but I think you may find a unique experience that, while slightly different from what you maybe thinking, they very well may tap into the vein you seek.
My optimal steeping time for M&P can be anywhere from 2 weeks to (I won't even say). LOL. As always, everyone is different.
