Synthetic drug use is on the rise in the Twin Cities. According to the Minnesota Department of Human Services, synthetic drugs are designed to mimic the psychoactive effects of traditional, illegal drugs like marijuana and various amphetamines. Even though synthetic drugs are sold online, many synthetic drugs are illegal like N-benzylpiperazine (BZP). Because of the rising popularity of synthetic drugs, seizures of BZP and related drug crimes are on the rise.
