Drugs are said to be brought into the country from the neighbouring countries through illegal borders.
Drugs are said to be having side-effects to the users, with about 22.6 percent of all patients received last year by the psychiatric hospital of Ndera who had mental problems caused by drug abuse.
According to Supt. Ngondo, the vice is on the decrease due to the measures initiated to combat it.

Each year, 2.5 million people die globally from drug abuse-related illnesses. Rwanda National Police calls for stronger partnership with the Rwandan community especially parents and Guardian to continue sharing information in order to deter and detect drug users and trafficking.
