Understanding the Legacies of Drug


Use in Armed Groups in the North


East of Nigeria

Armed conflict and black markets - arms trafficking,'
illegal resource extraction,2 or narcotic drugs3 - are
deeply intertwined. Unlike other illicit industries,
drugs are not only a key source of revenue for many
armed  groups, but also a strategic tool used to
sustain violence and control fighters.4 At the same
time, individuals associated with armed groups have,
in other regions, relied on illicit (and licit) substances
to enhance  aggression and  endurance  on  the
battlefield and cope with the physical strain, trauma
and psychological stress of war after exit.5 Exposure
to conflict presents several risk factors for substance
abuse,   such   as   mental  health   disorders
includingtraumatic stress disorder(PTSD), injuries
sustained during conflict, and difficulties transitioning
backto civilian life, including interpersonal


challenges and difficulties securing employment.6
Against this backdrop, this brief examines drug use
among  those once - or currently - involved in the
conflict in the North East of Nigeria, including former
associates of both Boko Haram7 factions - Jama'at
Ahl al-Sunna li al-Da'wa wa al Jihad (JAS) and the
Islamic State West Africa Province (ISWAP) - as
well as affiliates of community security actors such
as the Civilian Joint Task Force (CJTF) and the Yan
Gora and  drug use by their unaffiliated peers. It
raises questions about how drug use intersects with
conflict dynamics and reintegration outcomes and
highlights potential implications for policymakers and
practitioners working  on  conflict prevention,
disengagement, and reintegration efforts.
