ive read that it could have something to do with the actuall heating element the volcanoe uses which is said to be aluminum.. when the aluminum is heated alot it emits a harmful toxin in which the user would inhale...
Absolutely, positively NOT TRUE.

vaporfection stealth which uses a glass heating element, it is much cleaner, tastier, and alot safer.
How do you know it's safer? Just because the heater is glass? The construction materials of the heater aren't as important as the vapor path, and the Vaporfection doesn't have an all glass vapor path.

Comparing, safety wise, to the Volcano is a moot point anyway, since the 'cano is not an unsafe device.

If any vapes should be questioned, safety wise, it's all the cheap digital, made in China, no warranty vapes. For one thing, they're certainly not spending an extra nickel to avoid using components containing lead.

Although vapor is much kinder to the throat and lungs than smoke, you can't consume large quantities of vapor on a daily basis and not expect it to affect your lungs.
