Since legalization, the Washington state toxicology lab — the group that tests blood samples from DUI cases — says a lot more of samples are positive for marijuana. Three years ago, about 19 percent of the samples contained THC, the key ingredient in pot. This year, that percentage is up to 33 percent.
I live in Washington. I just don't look up the stats on the internet to try to make my point. Take a look at the NPR study. That refutes your "one data point" argument.
I realize that we are off topic, but marijuana has other societal and individual impacts as well. On the positive side, I understand that opioid addiction decreases substantially as do medical expenses.
