Where is Nicotine found?
Nicotine is an alkaloid found in the Nightshade family of plants, and constitutes of 0.6-0.3% of tobacco's dry weight
As far as abundance goes, Nicotine can be found in any existing tobacco plant!

How is Nicotine cultivated?
> grown using the standard procedure of scattering seeds and helping them to grow through water and sunlight.
> harvested annualy once they are large and mature enough.
> The oldest harvesting technique is manual - using a tobacco knife, harvesters cut the plants at their bases and then speared onto sticks with up to six other plants. In modern times, large tobacco fields are harvested mechanically.

Tobacco Curing
>Some tobacco is air cured, meaning it is hung and allowed to dry in well-ventilated barns.
>This tobacco has a low amount of sugar and high amount of nicotine.
>Fire cured tobacco is hung in barns where fires of hardwoods are kept smouldering continuously.
>This method takes between ten days and three weeks and also produces a product that has a low amount of sugar and high nicotine concentration.
>Sun cured tobacco is allowed to dry in the sun to create a gentler product. >Sun cured tobacco is low in both sugar and nicotine.

How is nicotine released from tobacco?
>Once tobacco is burned and inhaled:
>the nicotene within it is released in gas form and inhaled by the smoker.
>The nicotine in inhaled tobacco smoke moves from the lungs, into the bloodstream and up to the smoker's brain within 7 to 10 seconds.
