It is a tall evergreen shrub (2.7 to 3.7 m in height) that grows best at high elevations (1,500 to 2,000 m above sea level). Its tender twigs and leaves are harvested almost year-round.

When chewing khat, cathinone is released within 15 to 45 minutes, with peak plasma levels of cathinone obtained 1.5 to 3.5 h after the onset of chewing. Cathinone is detectable in plasma for up to 24 hours after consumption.El-Sayed 2012
100 to 300 g of fresh leaves are chewed to form a bolus that is held in the buccal sulcus against the cheek of the mouth while swallowing the juice it produces; chewing sessions typically last 3 to 4 hours.Al-Maweri 2017, Patel 2015 In Scotland, khat has been blended and filtered to be served as a drink called “Herbal Ecstasy.”Patel 2015
