Reported effects

In the UK archive, relaxed, euphoric, happy, uplifted, and creative are among the most frequently documented effects. Indica-dominant cultivars are more often associated with relaxation and sleepiness, while sativa-dominant cultivars tend toward energetic, focused, and talkative effects. Individual experience varies considerably.

Effects are recorded from original review sessions and community-reported data. They represent subjective experiences observed with specific samples — not predictable medical outcomes. Each effect page lists every cultivar in the archive where that character has been recorded.

A strain's effects are shaped by its cannabinoid profile (THC, CBD, and minor cannabinoids), its terpene composition, and individual factors like tolerance, setting, and consumption method. The entourage effect — the theory that cannabinoids and terpenes work together — is thought to play a significant role.

Indica-dominant cultivars like Northern Lights, Granddaddy Purple, and Purple Punch are frequently associated with relaxation and sleepiness. Browse the Relaxed, Sleepy, and Calmed effect pages below to find cultivars matching those characteristics.

Sativa-dominant cultivars such as Amnesia Haze, Super Silver Haze, and Green Crack are commonly reported to produce energetic, focused, and creative effects. Browse the Energetic, Creative, and Focused effect pages below.
