8.We know that cigarette smoking kills.So,producers made electronic cigarettes as a safer smoking choice-safer than tobacco.Although e-cigarettes contain the drug nicotine like cigarettes,they do not use tobacco and you do not light them.They are powered by battery.However,if e-cigarettes are so safe,why has the United States Center for Disease Control(CDC)seen an increase in telephone calls about e-cigarette poisonings?
The answer is children.Most of the calls are from people worried about children who have played with the devices,In the period of one month this year,the Center said 215people called the Center with e-cigarette concerns.More than half of these calls were for children aged five and younger.The devices had made them sick.
Tim McAfee is director of the Center's Office on Smoking and Health,He says the problem is regulation.Meaning,the U.S. federal government does not control e-cigarettes even though they contain liquid nicotine.Mr.McAfee adds that liquid nicotine is a well-known danger.Mr.McAfee explains that nicotine poisoning happens when it gets into the skin,gets into the eyes or is swallowed.It can cause stomach pain or a sense of unbalance.And too much nicotine can kill.
Tim McAfee says e-cigarettes do not create the level of risk to people that tobacco products do.He notes that almost 500,000Americans die each year from cigarettes."So,cigarettes are the winner in that contest."E-cigarettes do not contain hundreds of harmful chemicals that are found in real cigarettes.So,the U.S.Surgeon General Boris D.Lushniak has suggested that e-cigarettes may be a useful tool for adults trying to end their tobacco use.
But McAfee worries that teenagers may think electronic cigarettes are harmless.They could become addicted to the nicotine and then start smoking real cigarettes.In other words,he fears that for young people fake e-cigarettes could be a"gateway"to the real thing.
