The Marijuana Enforcement Division (MED) adopted new regulations that went into effect on January 1st, 2018, and further defined the legislative ban on looping. In particular, these regulations define a single transaction as multiple transfers to the same consumer made on the same business day and consider whether a licensee knows or should reasonably know that such a transfer would result in the consumer possessing more than one ounce of marijuana. These regulations also clearly define the quantity restrictions on sales.
