Yeah... I guess we could just wait until there is more proof... people used to think that smoking was good for chest congestion, that it loosened the phlegm... what a bummer that it turned out to be so bad. Ignorance can be bliss I guess.
Increasingly ill effects are not becoming evident until long after the use. I'm sure that the old folks who built their homes using asbestos would have laughed if somebody had said at the time that the dust from it would kill them. Just because something fails to immediately show a bad side affect doesn't mean that harm hasn't been done.
I don't get why people are annoyed with hearing that research is being done why is it so inconvenient to hear? My high-school level human biology/chemistry taught me that the human body is a fragile system... easily changed by things introduced into the system. You can compare the human body to the environment: 50 years ago the government PAID people to fall trees and clear land... they didn't know that this would lead to rising salt levels in the Murray Basin... it's only now that it has dawned on them "whoops"... billions of dollars might not even save the situation... surely people would do better having a more conservative approach to things and actually acknowledge that once you change one element of a system the whole will be affected in some way.
