went to purchase an ecig....there are 4 hanging on their wall, we looked at two of them, they had been used as you could see the vapor droplets on the tip of the ecig, and old black nicotine on the tip. When I called the clerk out on it, they didn't seem to care, and hung them all back on the wall to resell. I am currently working with Health Inspectors in Edmonton through Service Alberta to rectify this serious health issue. Those people could have had HIV, Hepatitis....anything
