Mkpuru Mmiri

Mkpuru mmiri is the Igbo name — literally “seed of water” — for crystal methamphetamine, a powerful stimulant whose use rose sharply in South-East Nigeria from around 2020 and prompted community campaigns across the region.

Key Points:

• What it does: a stimulant producing hours of energy, confidence and wakefulness, followed by a heavy crash. Tolerance builds fast, so the amount needed climbs quickly.
• Main harms: sleeplessness lasting days, sharp weight loss, dental damage, aggression and paranoia. Methamphetamine-induced psychosis — hearing voices, believing you are being followed — is common and can persist after use stops.
• It is often missed as a mental health presentation: a young person brought in for “madness” may be in stimulant psychosis, which changes what treatment is needed.
• Public shaming does not treat addiction: some community responses have involved beatings and forced public confessions. These drive use underground and make it far less likely that anyone asks for help.
• Treatment: there is no approved medication for methamphetamine dependence, so care is structured psychosocial treatment — contingency management, CBT, relapse prevention — over months. Families need their own support, since relapse is part of the course rather than a sign of failure.
