Trying to quit smoking cigarettes so bought electronic cigs is that safe for me being diabetic?

As a transition, yes: Cigarettes have cadmium and nicotine which cause inflammation, stress, and cause cardiovascular disease and cancer diseases more common in diabetics. Electronic cigarettes hopefully have mainly nicotine but your own body and air pollution can contribute the cadmium, the best thing is take sufficient vit d because cadmium breaks it down and commit to stopping both.
