In my first review of the Omicron and O-phos vaporizers I added a disclaimer that I was not aware of if there were any risks involved in using these vaporizers. When delta9 read the review they immediately contacted me to inform me on the subject. I appreciated this greatly and this just reaffirmed our belief that the delta9 are the best of the pen style vaporizers.
The first link I received was to the VECA and it contains a list of studies that answer the exact question I posed of "do we really know what is coming out of the cartridges". The second link sent was a small study from New Zealand regarding e-cig cartridges. The final link was information done by ANALYZE Inc, an independent consulting laboratory. I will leave the interpretation up to you but there is testing occurring and so far the results appear to show that the cartridges and their use are safe.
