The California State Health Officer issues a health advisory and a new e-cigarette report.  With rising use comes an alarming rise in harmful effects.   This bullet point was particularly poignant: E-cigarettes do not emit a harmless water vapor, but an aerosol that has been found to contain at least 10 chemicals that are on California’s Proposition 65 list of chemicals known to cause cancer, birth defects or other reproductive harm. http://www.cdph.ca.gov/Pages/NR15-12.aspx
