I have been smoking since I was 14, I am 38 now. I have been in bands most of my life playing in "smoking" bars. I have had over half of my life with 1st hand and 2nd hand smoke in me, I am fine. No cancer or anything and I can still sing good as ever.
Besides, anyone can put up a site like that and still not give the truth. Just because they calle it "thetruth.con" doesnot make it fact.
Look at the ads on tv for marijuana. I smoke pot too, I have never run anyone over, gotten pregnant or shot one of my friends.
It may be true, but it does not apply to everyone.
