Does the use of e-cigarettes affect plants?
Does smoking e-cigarettes around plants in a greenhouse have any effect on the plants like smoking regular tobacco cigarettes does?

The main problem with smoking around garden plants (especially in greenhouses) is that tobacco leaves--which make up the major part of traditional cigarettes, cigars, and pipe tobacco--can carry infectious tobacco mosaic virus. The virus doesn't harm people, but it can cause damage to a wide range of plants. The virus particles can be transferred to people who handle cigarettes and other tobacco products and then from those people to sensitive garden plants.
Because e-cigarettes do not contain tobacco, they cannot transfer any virus particles to greenhouse or garden plants. The vapor from e-cigarettes contains nicotine, which is a toxic insecticide but shouldn't harm any plants.
