This effect is distinct from actually causing the cancer (i.e., carcinogenesis). Indeed, propylene glycol and vegetable glycerine (PG/VG), the primary solvents in e-liquid and which have been assumed to be inert are major causes ofContinue reading “Dual cigarette and e-cig use increases human risk of lung cancer 40 times”
