Poor Brits! Don't know what they're getting into. Lead is one of the 5000
chemicals generated when you smoke cigarettes! Does that mean cigarettes
are going to be banned in the UK? Come on. Let's get real. There are so
many counter stories to Pb-free if anyone does research. Got my latest
CircuitTree issue with an article "Lead Free Groupthink" by Joseph
Fjelstad; got the latest Circuits Assy with an article saying the UK
didn't base their laws on Science, it was a political decision. Yada-yada.
Yes, we'll bear the brunt, and hopefully this will cause someones rump to
get whacked!
BTW, the cigarette findings were from a Peter Jennings expose' on the
cigarette industry the other night. Lead is one of the many 'banned'
substances that cigarettes emit. HAHAHAHAHAHA
Good day.
