i would know that my bud is giving me a nicotine buzz and il be like fuckit im jsut gonna buy a pack of marlboro 27's instead
weed doesnt need nicotine to make people continue to buy it, its perfect just the way it is (unless its schwag, then forget about it)
nicotine is a highly dangerous chemical in liquid form, one drop could potentially kill you, so i dont think dealers would go through the trouble to attain and use nicotine for their weed. They should just find some chronic to sell and they'll have regular repeat customers.
