Nicotine content of fresh green tobacco leaves versus dried tobacco leaves. Which has more?

[Mazdaman]

Which has more nicotine - a fresh, mature green tobacco leaf or a fresh, mature dried tobacco leaf? And why, or why not, if there is a difference? Thanks.

Belated welcome to the forum. Nicotine is produce in tobacco roots, and transported to the leaves. There, it is retained within the leaf lamina, with a small fraction excreted by the leaf hairs (trichomes) for herbivore defense. Nicotine does not evaporate during color-curing. So long as the mature leaves are not washed, their nicotine concentrations are similar.

Fresh mature dried?

Nicotine is a very stable molecule. The moment a leaf is cut, the amount in the leaf is fixed: green or cured, the amount is the same. How the leaf is subsequently processed, blended, and consumed all have an effect on the amount of nicotine that is absorbed.
