I'm not sure where leafly pulls data for its effects, it could be terpene profile, customer review, or even minor cannabinoids.

Terpenes can influence a high to feel certain ways, find out what terpenes have the effect you are looking for and target those.

Of course, everyone is unique, so what works best for you for certain effects may differ. However with a little bit of trial and error, and paying attention to the characteristics of how that strain affects you will help you dial in what to look for :)
