Can you get nicotine in your body from smoking weed in a blunt wrapper afyer you have taken out all of the tobacco?

Nicotine. It depends on if the wrapper is made of tobacco or paper and how much tobacco has been absorbed by the wrapper. I suspect it would be a small total amount. .
Probably. the wrapper probably has some residual nicotine. smoking weed can actually dilate rthe airway but the risk of toxin introduction into the lung remains.
Maybe. If the wrapper itself is a tobacco leaf then yes. If it is just paper then it is not very likely. Either way smoking is not good for your lungs.
