The most common drug in arrests in most U.S. states in 2017 was not marijuana, but methamphetamines, according to a study released Wednesday.

Crime data pulled from all 50 states indicated in 30 states, charges connected to methamphetamine use or possession were higher than those related to other drugs, including opioids, cocaine, pot, and other synthetic chemicals, according to American Addiction Centers’ Detox.net.
