The Colorado Enforcement Division - Marijuana published Industry-Wide Bulletin 18-11 informing medical and retail cannabis businesses that vaping cartridges, disposable vaporizer pens and syringe type devices that are intended to be used with marijuana or marijuana products must include a universal marijuana symbol on the container’s label. Colorado issued the guidance to clarify new the new requirements that come into effect as a part of the implementation of the permanent rules on January 1, 2019. The bulletin provides a phased in approach for licensees to comply with this new requirement. Licensees can choose whether to include the universal symbol on vaping cartridges, disposable vaporizer pens and syringe type devises until September 30, 2019. The universal symbol must be included on the labels on and after October 1, 2019. However, licensees can continue to sell inventory without the universal symbol until July 1, 2020 so long as it was received prior to October 1, 2019. Marijuana establishments should consider the lead time for obtaining new labels that include the universal symbol in order to ensure compliance with the phase in dates.
