From a very busy thread, with 400+ comments and 1200+ votes, at the time of writing: http://www.reddit.com/r/trees/comments/18nk52/why_i_believe_vaporizing_can_be_more_dangerous/ Here's the original post, by 'Greenwithenergy': I've owned every major brand vape you can think off. Years of use, and I found my lungs hurting more than ever. I mean, sharp pain. I'm an engineer so I started doing some homework (that I really should have done before hand.) 99% of vaporizers you see today use the exact same ceramic heating element made in a factory in China. I googled the serial number on the element inside my Volcano and tracked them down. The on inside my SSV was exactly the same. The company I contacted produces the ceramic heating element for almost every major brand blow dryer, heat gun, and soldering iron sold in the US. I asked if there is potential health problems using them as a vaporizer. I had to spend a good 20 minutes just explaining what a vaporizer was, luckily the office I work in has more than a few people who speak Chinese. When I was done, they told me they should never be used that way. Ceramic elements crack over time, like 6 months to a year. For most uses, this isn't a real problem, but if you're breathing directly off them, you can get ceramic microscopic chips directly in to your lungs. They force anyone in their factory testing the elements to wear masks for exactly this reason. When I explained that Americans were using the elements to heat plant material and smoke it, they were dumbfounded and quite alarmed. There overwhelming response to me was don't use vaporizers with ceramic elements, which is most of them. The fact is, most vaporizers are cheap, overpriced pieces of metal and plastic that have zero health benefits whatsoever and are actually far more dangerous than smoking. None of them are FDA approved, and when marketing them, a business can say literally whatever they want without penalty. In theory, the concept of vaporizing is sound. The practice of using ceramic elements to get the job done, in my belief, is not sound at all, and I hope some of you do some homework of your own. I really do believe more than a few of us are probably doing or already have done permanent damage using these ceramic elements. edit: It's been pointed out that at least two companies are using glass wrapped tungsten elements. I would encourage people to consider those as options. They can be found in the comments, as I don't want to appear to be advertising. If anyone know of more, feel free to post it here. I know there has been plenty of discussion on airpath quality here at FC (and indeed I'd be very surprised if the OP, Greenwithenergy, isn't an FCer). Some of the discussion has been in relation to ceramic heating elements, but obviously no consensus has formed strong enough to dissuade too many people away from buying vapes that use ceramic elements in their airpath. So what's are the current opinions at FC on this matter?
