Summary
Electronic Vapour Products (EVPs) is a relatively new class of consumer products that are otherwise known as electronic cigarettes devices/systems. These may look like conventional cigarettes but do not contain tobacco.
The 'vapour' produced by such devices typically consists of humectants (propylene glycol or glycerol), nicotine, water, and flavours.
This trial is to evaluate the safety and tolerability of an EVP over two years.
