Study: Electronic cigarettes pose health risks

Electronic cigarettes, which are increasingly used worldwide, are said to be unsafe and pose health risks, a new study suggests, reported China's Xinhua news agency.

Some people believe that e-cigarettes are a safe substitute for conventional cigarettes.

Batteries, atomizers, cartridges, cartridge wrappers, packs and instruction manuals lack important information regarding e-cigarette content, use and essential warnings; e-cigarette cartridges leak, which could expose nicotine, an addictive and dangerous chemical, to children, adults, pets and the environment.

Currently, there are no methods for proper disposal of e-cigarettes products and accessories, including cartridges, which could result in nicotine contamination from discarded cartridges entering water sources and soil, and adversely impacting the environment; and the manufacture, quality control, sales, and advertisement of e-cigarettes are unregulated
