"For comparison, the team asked more than 1,200 healthy individuals from across the same areas about their cannabis use. The strength of cannabis was estimated from the name individuals gave to the drug."

Oh yeah, that sounds solid. My dealer gave me "aghani super haze skunkworks MEGA-THCBOMB", therefore it has 13% THC.

As an avid cannabis user, the idea that you can link the "name" of what you bought to any chemical attributes of the substance is laughable. They will tell you whatever they think will sell it best. Weed "names" are entirely marketing.
