Regarding vaping and cigarettes and parasite activity - these and many other toxins, including dental toxins, attract, protect and feed all types of critters and can allow them to live inside our bodies. These toxins embed themselves in our organs which is why one would want to go through a Drainage protocol (detoxes the organs).
Dr. Omar Amin ( a top US Parasitologist in Scottsdale, AZ) has taught this principle and insists one must clean up all dental work and detox the chemicals out of the body. Dental work to be cleaned includes bad fillings, root canals removed, cavitations cleared, essentially no chemicals in mouth! He has many educational articles and videos on his website.
Chemicals attract the critters and weaken our immune system.
