A fine example of why Wikipedia is not an acceptable academic source. Its user generated, lightly scrutinized content. It could tell you anything.I would humbly suggest cutting down on the number of bowls a bit. Better to live to smoke another day, than to live without smoking.
Funny thing about the yerba mate: yes, the English page on the Whiskipedia says it's a cancer risk due to heat (if heat gave you cancer most coffee drinkers would be dropping like flies), yet the Spanish page says that yerba mate prevents tongue cancer due to the natural compounds in it. Whose science, or lack thereof, is correct? Enjoy your yerba, mate.
My understanding from the tea studies is that the elevated cancer risk is in folks who drink ridiculously hot. Warm Was fine IIRC, just super (tissue damaging) levels of hot were risky. I guess.
