Följderna av narkotikamissbruk kostar samhället stora summor pengar varje år. Att beräkna den exakta storleken på dessa summor är omöjligt, eftersom stora delar av den narkotikarelaterade verksamheten är olaglig. De kostnadsberäkningar man kan göra blir ungefärliga uppskattningar. Ändå är det viktigt att försöka, eftersom den kunskap man har om kostnaderna för narkotikamissbrukets konsekvenser utg
