Police in West Jordan, Utah, carried out a drug bust on Friday 4 January 2019 in which officers seized hundreds of THC cartridges intended for vaping pens.[1] Investigators said the man behind the operation was Juan Cruz Castruita, described as the leader of a gang called the Polo Getto Boys.[1] Police said the gang used the messaging app Snapchat to distribute the product.[1]

Sergeant Holt of the police said ordinary vape oils contain nicotine, while vaping a THC oil is basically the same as smoking marijuana.[1] Police linked their concern to the popularity of vaping among high school students, citing a national study the previous month that found one in three seniors had vaped.[1] Sergeant Holt said the effect on schools, if the cartridges reached them, was huge and far-reaching.[1]
