Saw this on the net
my brother ordered the lights, its electronic cigs, with no tar, no ash, no carcinogens etc, and they also have non-nicotine versions
and the 1 case (25 blu cigs) equals to over 300 normal smoking cigs.
from FAQ "What are the ingredients in e-liquid?
blu cartridges contain nicotine (in levels of high, medium, low and no nicotine), propylene glycol, tobacco flavoring, and other flavoring ingredients exclusive to blu. These cartridges come in various flavors and nicotine levels to satisfy the needs of a variety of smokers. Propylene glycol is a water-based ingredient found in many health products and medicines. None of the ingredients in the cartridges have been found to be carcinogenic. "
