Yeah @Walt, I said that tongue-in-cheek, with a hint of sarcasm... I have full faith that every politician with a vested interest in upholding their cash-cow of tobacco taxes, will fully rebuke this study and tout it as tainted or bias... and sweep it under the rug! The author of the study will likely be drawn-and-quartered on the capital lawn... or at least fired....
Which is why I forwarded the link (and text) to my Representatives and Senators at the state and Federal levels, as well as my state Attorney General, local and state Health Departments, and a few hundred of my friends. CA says breathing causes cancer, so a study from CA that says second-hand vape has NOTHING in it that is harmful (moreso than normal air)... is HUGE info, and must get out there!
