The pill is reportedly a potent threat to young people, who risk ingesting heavy doses of the drug by being deceived by its innocuous, colorful, candy-like appearance. It should be noted that the drug is extremely addictive and deadly, despite its rainbow hues.In a similar incident on December 1, 2022, the Los Angeles Fire Department responded at Van Nuys Middle School in Sherman on report of a possible overdose. Upon arrival, authorities reportedly found ten students aged between 12 and 15 began exhibiting overdose symptoms after ingesting unidentified edible cannabis.
