From DAVID HUGHES
Re ‘Legal Drugs’ (‘Life, the Universe and (almost) everything’, 18 September):
I think there has been some confusion with milli and micrograms. One puff
of a cigarette does not contain 350 milligrams of nicotine – if it did,
smoking would certainly be injurious to health – instantly fatal.
