Many pot smokers have had to endure buzz-killing bad trips while searching for the weed strains that are just right for them.

Folks sparking up to find some creative inspiration can be left feeling lethargic, for example, while tokers hoping to catch some sleep can actually wind up feeling wired. That’s largely because the limited designations for different types of cannabis, particularly during its prohibition, haven’t actually been steeped in science — until now.

Seattle-based Leafly, the world’s largest cannabis website, launched an exhaustive guide last month “that redefines the way people understand cannabis and find the feelings and effects they want,” the company says. Maria Sharp, Leafly’s marketing manager of education and evangelism, laid out the new resource during an event earlier this week in West Town that marked the seventh stop on a 16-city tour.

“It’s about graduating from an antiquated, inaccurate and unreliable system” of labeling marijuana simply as indica, sativa or a hybrid of both, Sharp said. “For years, we’ve been using those as descriptors of what a final product can make us feel like, with indica being more sedative and sativa being more uplifting.”

“That system just doesn’t work,” she said.
