Tobacco may actually have a health benefit towards fighting cancer.
Researchers at Stanford used tobacco plants to create personalized cancer vaccines. 16 patients with a specific type of Lymphoma participated in the study. Cells from their tumors were injected to special tobacco leaves, then the plant cells grew and created antibodies against the tumor. Researchers then ground up the leaves and created a vaccine.
This study was only looking at vaccine safety and researchers report none of the participants experienced major side effects. 70 percent of the patients had an immune response to the vaccine.
