First, legal pot is attracting new and possibly naïve users — creating risks that some don’t bargain for. Second, the public health system’s desire to protect people may be well-intentioned, but regulation and efforts to track the health effects have a ways to go.

Dude had only smoked pot twice in his life, about 25 years ago, but he got curious and tried some pot gummy bears from a shop called the LoDo Wellness Center. Other than being infused with THC they looked and tasted like ordinary candy. Dude and his buddy paid $20 for a pack of 10.

Dude ate a bear before dinner but felt nothing. So he popped another during the meal. Nada. Ripoff, he assumed. So he ate a few more — five total, he said — but still felt nothing. He fell asleep in his hotel room at 11 p.m.

Two hours later, Dude awoke feeling like he was on a roller coaster. His entire body tingled, and he was light headed. He tried to stand, but his left leg was so numb he couldn’t walk to the bathroom. His pounding heart strained his rib cage as waves of euphoria and anxiety washed over him.

He was terrified.

Was this the high? An overdose? A heart attack? A stroke?
