Electronic Cigarette Research


According to some criticism of the electronic cigarette little or no research of the electronic cigarette has been carried out. (Some of this criticism originates from bodies ECigaretteDirect invited to participate in research but who ignored our call!)

This is not in fact the case, with several analyses being carried out and more in the the process of being carried out. ECD is in the process of collating this research and summarising this research, with links to the complete and original research documents where possible.
