Some parents talked about how their teenagers slowly became hooked on various forms of marijuana concentrate, which now ranges from 50 percent to upwards of 90 percent THC, while other parents, whose children are medical marijuana patients, as well as adult patients testified that those same products are what they need to keep their lives comfortable. "We're hearing more and more about how the market is changing away from traditional flower and toward concentrates," said House Speaker and bill sponsor Alec Garnett, adding that he's concerned that eighteen-year-old medical marijuana patients who haven't yet graduated are “using the loopholes in our system to divert product into the high school.”
