Keith Laham and his friends have been practicing for the past few months.
They have gathered in his cellar, in other people’s cellars — you name it, the 42-year-old West Roxbury native said.
But this weekend will mark the true attempt, and Laham, cofounder of Beantown Greentown, a medical marijuana advocacy group, lifestyle brand, and cannabis club, has high ambitions for it.
During the inaugural “Harvest Cup” in Worcester on Saturday and Sunday — a gathering of promarijuana vendors, industry leaders, and speakers — Laham and up to 40 volunteers will try to craft a 100-foot-long joint to set an unofficial world record.
The weekend-long gathering, which will take place at the DCU Center, is sponsored by the Massachusetts Grower Advocacy Council, MassCann/NORML, and the Massachusetts Patient Advocacy Alliance. The Harvest Cup is a nonconsumption event, organizers say, and is open to people 21 and over.
“It seems so ridiculous, a 100-foot bone,” Laham said. “And it is, when you think about it.” But that doesn’t mean it can’t, or shouldn’t, be done, apparently.
The effort is to be completed Saturday at the significant time of 4:20 p.m. — April 20 is considered “Weed Day.’’
Laham said that to accomplish the feat, the group will bring just over 2 pounds of marijuana to the event and lay it out on a long table.
It will then work in smaller groups to build the joint, funneling the leaves into strips of paper, before eventually stitching them together to make one consecutive joint, he said.
“It’s pretty much impossible to roll a 100-foot bone by throwing paper out there and trying to just roll it,” Laham said. “But when we get sections and teams of people, then we will be able to do it. We will have guys running up and down making sure it gets connected in the right places.”
The possession and consumption of recreational marijuana was legalized in Massachusetts last year. It’s against the law to smoke it or use marijuana-based products in public places, however. The state Cannabis Control Commission has been crafting regulations for the new law.
Peter Bernard, president and director of the nonprofit Massachusetts Growers Advocacy Council, said the event will probably draw 4,000 to 6,000 people interested in the burgeoning industry and the history of the marijuana-legalization movement. He described it as a cannabis trade show, expo, and competition.
Attendees will not be able to purchase any THC-based products this weekend but can sit in on speaker sessions; watch live demonstrations on how to make marijuana-laced foods; and learn about businesses in the region, he said.
Bernard said Beantown Greentown approached the council when the group learned about the Harvest Cup and asked if it could attempt to build the joint on site.
“And we said, ‘Come on down, it would be a great thing to have,’ ” Bernard said.
Organizers tried to get Guinness World Records to attend, for a shot at getting Beantown Greentown in the books, but the request was rebuffed.
“We currently do not monitor this category as it is deemed illegal under British law,” a Guinness spokeswoman said in an e-mail. “As we are based out of the UK, it is our policy to monitor record titles that are legal under British law.”
Still, Laham and his friends will forge ahead.
During practice runs, the group has managed to build a 93-foot joint using a combination of marijuana from multiple people. Laham is certain that adding an extra 7 feet to the joint they create this weekend won’t be an issue.
There is one problem on his mind, however: “The only unfortunate part is that we can’t smoke it inside the DCU Center,” he said. “It would be epic to smoke a 100-foot bone.”
Instead, they might cut it up into sections, and give away smaller joints as a memento to mark the occasion, he said.Steve Annear can be reached at email@example.com. Follow him on Twitter @steveannear. Information from the Statehouse News Service was used in this report.
