Big tobacco companies are pushing a range of control on e-cigarettes, they include lengthy warnings, restricted sales, reduced product ranges  and scientific testing requirements.

Nicotine, the e-cigarette warning says, is “addictive and habit-forming, and is very toxic in inhalation, in contact with the skin, or if swallowed.”

MarkTen, a leading brand in the U.S. says “nicotine can increase blood pressure and cause dizziness, nausea and stomach pain.”

Altria, the parent company of MarkTen which makes Marlboro cigarettes said that there is no warning in electronic cigarettes in U.S.

The health warning produced by Altaria on electronic cigarette is 116 words long and is far longer than the traditional cigarettes.

According to the World Health Organization (WHO), tobacco kills almost 6 million people each year.

E-cigarettes have been introduced in 2006, since then smokers in order to get over their smoking habit are moving towards e-cigarettes.

Big tobacco companies say that they are pushing for firm control on e-cigarettes is not to hurt smaller competitors.

“Our stated goal is to get to e-vapor leadership, to have the strongest brands in the marketplace; I don’t know how they run their businesses and what it would cost them to meet those requirements.” Said the Altria spokesman

Late 1990s, big companies led a campaign for cigarettes to be regulates by the U.S. Food and Drug Administration. The small companies say that this is the tactic which they played to drive away small competitors.
