A pen for wax is not blowing clouds and it's something you don't hit all day long. Also you are correct. People should be worried about this stuff. I remember years back a college student at Berkeley or some shit started realizing his throat was always sore and felt like he had shit in it. After doing research on his vape for bud he noticed the metal they use is not meant to be heated up to that degree. The kid even got in contact with the distributor in China. Who told him they are not meant to be put to your mouth and inhaled. Upon more research it was shown the metal when heated up so high has metal spore get spewed out into your lungs. This isn't that bad unless you smoke everyday all day with it. The kid threaten to sue the vape company who promised they would stop using metal that shouldn't be heated up so high.

The fact is these companies have no regulation as people like the fda don't acknowledge vaping that much. Plenty of companies buy parts out of China then assemble the pen here. Which means many manufactures have no idea that the metal chamber they just sold is going to be heated up and Inhaled. So yeah kids need to be careful with vaping now a day. It's the tobacco companies of this generation. Remember how our parents didn't think smoking was bad until later in life. Well vaping will probably be that next type of product.
