Bigstock As pot legalization rolls through the U.S. like a modern-day Johnny Reeferseed, there have been concerted efforts to continue the demonization of weed that has lit up prohibitionists for decades. Even as advocates work to pass initiatives to legalize, tax and regulate marijuana for adult-use or for medical patients, there is a parallel phenomenon amongst elected officials proposing legislation intended to neutralize the cannabis laws that enjoy majority support from citizens across the country. In states across the country, lawmakers have sponsored bills that seek to set limits on THC blood content for DUI, create THC caps for flower and other cannabis products and fund studies to determine the correlation between pot smoking and violent behavior or mental illness.
