Ok, maybe opening/reopening a can of worms here folks. Isn't silica a harmful substance? I know silica dust is very harmful for the respiratory system. I was using it for a while but went on to the organic cotton which in my opinion is every bit as good a vape if not better. I have been searching but not had any decent information on the web. Do fibres in the wick differ from dust?
