What's causing the massive spike in marijuana poisoning in young kids?

Recreational marijuana has been legal in Michigan since 2018, and cannabis use is up. But, marijuana poisonings are also up, not just in Michigan, but nationwide. The National Poison Data System tracked a 245% rise in pediatric abuse and misuse of cannabis from 2000 to 2020, with the biggest increase happening from 2017-2020 when cannabis legalization really started to grow.
