Miraa- is a plant whose fresh leaves and soft twigs are chewed to release a juice containing cathinone and cathine, the active chemicals that alter the mood of the abuser.

When consumed, these plants cause an intense burning sensation of the mouth, throat, lips and tongue; excessive drooling, choking, gagging and potentially serious swelling of the throat that could cause difficulty or the inability to swallow (dysphagia).
