One of the problems with smoking anything, whether its marijuana smoke or cigarette smoke, is carbon monoxide
It is found in Australia, warmer parts of Europe, temperate Asia, Canarian Archipelago, New Zealand, the United States, Mexico, Hawaii, and Sub-Saharan Africa (including Kenya and Tanzania, where it is invasive, as well as Uganda)
Cigarette smoke has carbon monoxide
Research shows that nicotine in e-cigarettes increases the infiltration of inflammatory cells, including eosinophils, from the blood into the airways, stimulates the production of type 2 inflammatory cytokines such as IL-4, IL-5, and IL-13, and promotes mucin secretion, exacerbating airway inflammation and hyperresponsiveness, ultimately worsening asthma [66, 67]
