Scientifically no, the chemicals in Blu e-cigs are harmful to your lungs as any vapor is, however the smoke from "Grass" has been shown to stop seizures and heart-attacks, and some unbiased proof is that my grandmothers neighbor had a child who has seizures at random, up till the age of 6 she was having these seizures everyday and at one point was stuck in the hospital, now this young girl moved to Colorado and started taking Marijuana on a regular, in edible or oil form and today she has no seizures except for every 2-3 months so to finally answer, no ecigs are not healthier
