Nasal snuff is my only nicotine ,most of the time.I may very seldom smoke a pipe(don’t inhale any smoke in your lungs,please).I find snuff <and nicotine in general> to be used in a sedentary activity because it stimulates the mind and attention but makes your body somewhat dull.Caffeine is much much better for physical activity.Snuff seems to be the best form of tabacco to be used for nicotine’s noorotropic effects and pipe/cigars a bit better for recreative purposes,especially with some alcohol.However,any smoke makes my gums and tongue irritated so i don’t do with any regularity.Again,please don’t inhale smoke in your lungs
