letter in this week's people newspaper :
The People stated last week that fake cigarettes contain arsenic. But all cigarettes contain arsenic and it is perfectly legal.
Among other ingredients in real cigs are hydrogen cyanide, hydrazine, ammonia, butane, toluene (embalmer's glue)and formaldehyde.
In fact there are many more toxic ingredients in the real thing. So basically fake cigarettes are no more dangerous than legal cigarettes. Light up and enjoy folks!
