Right. 70 cases of overdosing plus 2 cases where people were killed = "inflating the risk."
And these are just the cases we know of; how many people overdosed and did crazy shit that never made the news?
Going to the hospital because you feel dizzy doesn't mean you overdosed. And out of the staggering amount of cannabis sold in Colorado last year you're concerned with 2 deaths? One of whom was also on prescription pain meds?
