Safety Report on the Ruyan® e-cigarette Cartridge and Inhaled Aerosol

August 30, 2008
By Murray Laugesen

Report by Ruyan® on its e-cigarette and cartridges.

Aim: This report aims to assist regulators in initial assessment of the safety of the Ruyan® e-cigarette and its cartridges, and the possible risks and benefits from permitting its use.

Method: Health New Zealand Ltd contracted with seven leading government, university and commercial laboratories in New Zealand and Canada to independently perform various tests on the Ruyan cigarette’s nicotine refill cartridge.

Findings: Ruyan® e-cigarette is designed to be a safe alternative to smoking. The various test results confirm this is the case. It is very safe relative to cigarettes, and also safe in absolute terms on all measurements we have applied. Using micro-electronics it vaporizes, separately for each puff, very small quantities of nicotine dissolved in propylene glycol, two small well-known molecules with excellent safety profiles, – into a fine aerosol. Each puff contains one third to one half the nicotine in a tobacco cigarette’s puff. The cartridge liquid is tobacco-free and no combustion occurs.
