List of national legal systems
Common law is currently in practice in Ireland, most of the United Kingdom (England and Wales and Northern Ireland), Australia, New Zealand, Bangladesh, India (excluding Goa), Pakistan, South Africa, Canada (excluding Quebec), Hong Kong, the United States (on a state level excluding Louisiana), and many other places. In addition to these countries, several others have adapted the common law system into a mixed system. For example, Nigeria operates largely on a common law system, but incorporates religious law.
Single Convention on Narcotic Drugs
Drug enforcement varies widely between nations. Many European countries, including the United Kingdom, Germany, and, most famously, the Netherlands, do not prosecute all petty drug offenses. Dutch coffee shops are allowed to sell small amounts of cannabis to consumers. However, the Ministry of Health, Welfare and Sport's report, "Drugs Policy in the Netherlands", notes that large-scale "[p]roduction and trafficking are dealt with severely under the criminal law, in accordance with the UN Single Convention. Each year the Public Prosecutions Department deals with an average of 10,000 cases involving infringements of the Opium Act." Some of the most severe penalties for drug trafficking are handed down in certain Asian countries, such as Malaysia, which mandate capital punishment for offenses involving amounts over a certain threshold. Singapore mandates the death penalty for trafficking in 15 g (half an ounce) of heroin, 30 g of cocaine or 500 g of cannabis. Most nations, such as France and the United States, find a middle ground, imposing a spectrum of sanctions ranging from probation to life imprisonment for drug offenses.
