The health consequences of tobacco use have been well documented. According to the World Health Organization, more than 8 million people worldwide succumb to tobacco-related illnesses, such as lung cancer, heart disease and chronic obstructive pulmonary disease, every year. For every person who dies due to tobacco, at least 30 people live with a serious tobacco-related illness, according to a 2019 policy brief by Tobacconomics.
Among the most striking examples of tobacco’s potential to heal rather than hurt are recent endeavors to develop an inoculation against the novel coronavirus.
In February, Health Canada approved Covifenz, a tobacco plant-based Covid-19 vaccination developed by pharmaceutical giant GlaxoSmithKline and Medicago, a biopharmaceutical company backed by Philip Morris International.
According to Health Canada, Covifenz is the world’s first vaccine approved for human use that utilizes a plant-based protein technology.
As it turns out, plants—and especially tobacco plants (see sidebar)—lend themselves exceptionally well to developing pharmaceutical compounds. In many ways, they are better suited to the task than the man-made bioreactors used in traditional vaccine development.

Plants are natural bioreactors, according to Dahlia Garwe, the former CEO of the Kutsaga Tobacco Research Station in Zimbabwe. “They are able to perform eukaryotic post-translational modifications that are often essential for biological activity of many mammalian proteins.”
