    Thanks for this, Steven. Wasnt the Fairbanks (and Palmer etc) anti-fluoridation decision based mainly on the hip-fracture scare?

    Re: “Colorado Brown Stain and Fluoridation

    I dont think its black and white though, Joel. I liked how one study (published in the Lancet back in 2000) ended, looking at fluoridation vs. hip fractures (the latter being a Big Deal in older peopleum, like me):
    There is a low risk of hip fracture for people ingesting fluoride in drinking water at concentrations of about 1 ppm. This low risk should not be a reason for withholding fluoridation of water supplies.
    Against that, theres a metastudy (PLoSOne 2015) which pretty much debunks the osteoporosis-F link.
    But the vaccination link is obvious, as I said in the column, personal rights vs. community benefits. So many examples we just take for granted: chlorinating water supplies, speed limits, crash helmets for bikers, censorship, drug laws, you name it. (I feel another column coming on...)

    Re: “Cannabis-Related Lights Polluting SoHum Skies

    I assume noise pollution from generators accompanies the light pollution?
