Damage to the lungs is caused primarily by cigarette smoke. Cigar smoke is not supposed to be inhaled, and so should not reach the lungs. Cigarette smoke contains tar. That tar gets into the lungs and clogs the alveoli, the tiny pockets in the lungs that take in oxygen and release carbon dioxide.
blu eCigs perform somewhat like traditional cigarettes. They look, feel and taste the same, but blu eCigs deliver all the pleasures of smoking without any of the tar and carcinogens that are associated with traditional cigarettes.
blu is driven by the latest microelectronic technology - a small rechargeable battery and a unique, replaceable cartridge containing water, propylene glycol, nicotine and other flavorings exclusive to blu. These are all contained in a membrane within the cartridge to suspend the ingredients and keep blu fresh while stored.
With blu, the act of inhaling - or "smoking" - produces the tactile and cravings satisfaction smokers desire. It also triggers a vaporizing process that releases simulated smoke, which is actually a vapor that evaporates into the air within a few seconds.
