Four bills intended to beef up Minnesota’s drug laws were passed by the Senate Judiciary and Public Safety committee on Thursday. The bills would change laws related to bong water and make synthetic marijuana and 2C-E illegal substances. The measures seek to address high profile controversies over the last two years, including the case of a woman who was sentenced to prison because the state Supreme Court ruled bong water to be a drug, the death of a Blaine teen in which 2C-E was suspected and the hospitalization of a Hastings teen after he smoked synthetic marijuana.
