tobacco is known to give sinus infections when smoke is inhaled or exhaled through the nose because the nicotine paralyzes mucous membranes, making the nose dry and prone to virii and bacteria.

if you dont smoke cigs i doubt its from the weed.

being diagnosed with chronic sinusitis multiple times, i can tell you that refraining from blowing or inhaling any smoke from your nose will help the situation, and possibly prevent it.

the post above me had a good point too.
sliver Reviewed by sliver on . Weed and Sinus Infections, correlation? A few weeks ago I was having horrible tooth pain and constant headaches (they were more painful and prominent when I would smoke weed)--went to the dentist and only had one cavity. The tooth pain and head aches were actually caused by a sinus infection and the Dentist gave me some antibiotics--headaches went away. I'm getting the same toothache & slight headache combo again now just a lot less frequent and a more dulled pain and I think it happens more when I'm burning. Does anyone know if Rating: 5
