SAUGUS — The Town of Saugus may take a big step tonight in the realm of recreational use of marijuana. In the third installment of the annual Town Meeting, which gets underway at 7:30 in the third-floor auditorium at the Town Hall, members are expected to be asked to amend the vote they took four years ago that prohibited the operation of any retail-marijuana establishments. This prohibition did not apply to the sale, distribution, or cultivation of marijuana for medical purposes. The first installment took place May 2 and dealt mainly with monetary items on various pieces of equipment and maintenance around town. Last week, the majority of the meeting dealt with zoning amendments that centered around the composition of high-rise office and apartment buildings in the town, both along and away from Route 1. The warrant contains 38 items, with most of them still to be discussed. Article 36 of the warrant asks the town to amend the definition of “marijuana establishment,” to include language governing recreational use of the drug. It would read as follows: “recreational marijuana retail establishment (RMRE): a use operated by an entity duly licensed by the Cannabis Control Commission in accordance with state law, and pursuant to all other applicable state laws and regulations that sells, distributes, dispenses, delivers, administers or allows for the on-site consumption of marijuana, products containing marijuana, or related supplies for rails sales for non-medical purposes.”After a state referendum approved the use of recreational marijuana in 2016, the town rejected it. However, Selectman Jeff Cicolini was among some members of the board to ask that the town revisit that vote during a meeting in February. Cicolini said the town was missing out on tax dollars by not having recreational dispensaries. Also in favor of recreational marijuana is Board of Selectmen Chair Anthony Coglino. “I’m 100 percent in favor of it because No. 1, we need the additional revenue,” Cogliano said. “There’s quite a bit of money generated from those facilities and they are all around us. I’ve been to quite a few of them just to see how they are run. The one in Melrose — it’s incredible. There are no cracks in that system at all.”
