Likely that something else is present in your sinus cavity, and is being irratated with pot's gooey, resiny smoke.

Anyone who's body rejects the presence of cannabinoids will encounter something a lot more bothersome than a splitting headache.

Advil doesnt do much for ya when the body is in even the most mild state of anaphylactic shock.
slowthestone Reviewed by slowthestone 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
