Yes I know that many pharmaceuticals and everyday nutrients become unsafe at certain levels (even water). But can you truly say there is any safe level of tar, nicotine, carbon monoxide, formaldehyde, hydrogen cyanide, and benzene?
BTW Nicotine makes a great pesticide. [/QUOTE]Let me turn the question around. At what point does tar, nicotine, CO, etc. become
unsafe? Can you say that there is
any increased risk at the fractional parts per trillion detection limits we have today? Where does the risk start?
