i think if any part of u goes numb while smoking thats just a side effect or sum shit & it all depends on ur body But me personally my lips & my eyelids go numb, more-so my eyelids
My eyelids and a couple of times my ass had gone numb. If I smoke a shitload then I get to where I can't feel my feet and just shiver a lot.
na... im positive it wasnt. i'm pretty sure it comes from hitting a bowl a different way than usual. its happened a lot to me, with all sorts of diff. buds.
