The problem of perceived political mandates is related of budget mandates. Policymakers make laws and policies (rationally) on the basis of perceived constituent demands, thus driving out policy analysis from the process. As will be discussed further in this chapter's case study, strict enforcement of marijuana laws may paradoxically be driving people to use cocaine and more harmful drugs. Zero-tolerance laws and harsh sentencing for possession of marijuana have increased the risks of cultivation, and this has encouraged growers to produce more potent strains of the drug that bring a higher price with a lower volume of sales (Schlosser 1977, 99). Consistent with basic market economy principles, price increases can lead to gains in producer efficiency.
