thats a myth, Alzheimer's is always used to scare off people from smoking in general, if you place the herb directly on the surface of the pot or pan rather then aluminum your chances of smoking any lethal chemical are 1 percent compared to cigs and most of these funky paid for vapors, drinking coffee is more harmful, this is totally medical, free and works



read this:
Some of the best vaporizers on the market use aluminum heating elements. 'One reason the Volcano maintains such perfect temperature control is usually because it uses an aluminum part and block, and aluminum has different properties than potential practical designs using ceramics. An aluminum part and block can more quickly adjust for effects of air pressure and flow over plant material...the key to vaporization is maintaining control over temperature and flow, which ultimately leads to more perfect control over vapor density.'
Critics of vaporizers with aluminum heating elements cite health risks associated with exposure to aluminum, specifically a heightened chance of Alzheimer's.
So a well designed aluminum heating elements seem to be quite clean.
As for the increased chance of Alzheimer's : it's tough to be certain whether something does or doesn't play a part in the development of Alzheimer's as the sickness itself isn't completely understood, but aluminum does not seem to seriously increase a person's sensitivity. These articles from systematic American and Alzheimer's.org discuss this conclusion in depth.

Aluminum is safe :P
