Thank you.
Well, in long-term studies, actually—I'm talking about the Neeson study in New Zealand.... They reported on decreased IQ, school dropouts, increased attention span problems, and again the impairment of higher cognitive and executive functionings. That's a significant increased risk to youth. There is also the increased risk of MVAs, which of course we would be concerned about for young people.
I want to make reference to the harmful effects on the lungs that were mentioned here by Ph.D. Kevin Sabet, showing an increased risk of bronchitis, cough, and phlegm production. He claims that there are 50% to 70% more carcinogenic hydrocarbons than in tobacco use. You talk about there being no significantly established health risks; I wonder how you respond to 50% to 70% more carcinogenic hydrocarbons. He went on to say that marijuana smoke contains an enzyme that converts hydrocarbons into a cancer-causing form, something on which he didn't actually elaborate scientifically.
I wonder how you relate those potentially cancer-causing risks for the lungs—I think I heard one of you suggest that it may be a cancer treatment, which I find quite astounding—and furthermore the contention that persistent and heavy use among adolescents reduces IQ by six to eight points. That would be a concern, I would think, to most people wanting to see a young generation grow up to become highly productive adults.
