Barb Tarbox, MSM (April 10, 1961 – May 18, 2003) was one of the most well-known anti-smoking activists in Canada; a life-long smoker dying of brain and lung cancers whose very open and frank discussions of her illness, its cause and its consequences, propelled her to the Canadian national stage. During the last months of Tarbox`s life she went around Canada teaching young adults the consequences of smoking. Perhaps most memorably, she emphasized how she was unable to quit smoking even after she found out that she had cancer.
