Smoke exhaled by smokers (mainstream smoke) and smoke emanating from tobacco burning from their cigarettes, cigars or other (side stream smoke) mixed with ambient air. Second-hand smoke contains in particular more tar and carbon monoxide than mainstream smoke. The particles generated by this smoke are smaller and thus penetrate deeper into the lungs.
WHAT YOU SHOULD KNOW! A co-owner bothered by second-hand smoke could consider a legal remedy for neighbourhood annoyances against the co-owner concerned. The plaintiff will nevertheless have to show that this nuisance is abnormal, and that it exceeds the limits of the tolerance that the neighbours owe to each other under article 976 of the Civil Code of Quebec.
