I always thought that nicotine as such wasn`t very dangerous for your health, the main damage by consuming nicotine is the smoke as such. About 0,5 gram of nicotine would be deadly which means about 500 Cigarettes for a grown person. So there are ways to get nicotine without smoke, Snus or Snuff and E-Cigarette (Which doesn`t exist long enough, so we will find out how dangerous they are :D)

For me ... Alcohol wasn`t ever a thing, CBD doesn`work on me, so no need for weed, the others, never tried, never will try ... only nicotine this son of bitch ... if any one finds an Darth Vader Mask - E-Cigarette so i can breath through it, call me :D
