Earlier this month, when Ellen Epstein arrived at the Devil’s Thumb Ranch in Tabernash, Colo., for the wedding of her friends Lauren Meisels and Bradley Melshenker, she, like the other guests, found a gift bag waiting for her in her hotel room. But rather than a guide to activities in the area or a jar of locally made honey, the canvas bag contained a rolled joint, a lighter and lip balm infused with mango butter and cannabis, along with this note: “We wanted to show you some of the things we love the best.”

She knew then that the wedding of her fellow Boulder residents would be just a little different from the ones she had attended in the past.

The Meisels and Melshenker nuptials looked as if their inspiration had come not from the pages of Martha Stewart Weddings but from High Times. All of the floral arrangements, including the bride’s bouquet, contained a variety of white flowers mixed with marijuana buds and leaves. Mr. Melshenker and his groomsmen wore boutonnieres crafted out of twine and marijuana buds, and Mr. Melshenker’s three dogs, who were also in attendance, wore collars made of cannabis buds, eucalyptus leaves and pink ribbons.

Before going into dinner, the guests were given a baby marijuana plant in a ceramic pot with their name and table assignment written on a card in green ink, in the kind of stylish script you might find on a container of artisanal goat cheese. The tables were named after different strains of marijuana, like Blue Dream, Sour Diesel and Skywalker (the groom’s favorite strain). Ms. Epstein, who was seated at Skywalker, said that everyone at her table, where the ages ranged from 40 to 70, passed around a device similar to an electronic cigarette — except that it contained hash oil instead of nicotine. “It didn’t feel weird or bizarre,” she said. “It kind of becomes a new cocktail.”
