Got hayfever? It's time to rip out the cause by the roots.

The Quebec Lung Association is launching its annual campaign to eradicate that scourge of allergy sufferers, ragweed.

Quebec's Ministry of Health estimates one in eight Quebecers has seasonal allergies, especially to the pollen shed by ragweed.

The Lung Association says medical complications due to hayfever and other seasonal allergies cost the health system $157 million each year.

45 cities are taking part in this year's campaign incliding Longueuil, Brossard, Sherbrooke and five boroughs in the city of Montreal.

Hudson is not an official participant in the campaign, but it is offering residents 10 cents per kilogram of ragweed they remove from the region.
