trade policies. After American independence in 1783, smuggling developed at the edges of the United States at places like Passamaquoddy Bay, St. Mary's in Georgia, Lake Champlain, and Louisiana. During Thomas Jefferson's embargo of 1807-1809, these same places became the primary places where goods were smuggled out of the nation in defiance of the law. Like Britain, a gradual liberalization of trade laws as part of the free trade movement meant less smuggling. in 1907 President Theodore Roosevelt tried to cut down on smuggling by establishing the Roosevelt Reservation along the United States-Mexico Border. Smuggling revived in the 1920s during Prohibition, and drug smuggling became a major problem after 1970. In the 1990s, when economic sanctions were imposed on Serbia, a large percent of the population lived off smuggling petrol and consumer goods from neighboring countries. The state unofficially allowed this to continue or otherwise the entire economy would have collapsed. In modern times, as many first-world countries have struggled to contain a rising influx of immigrants, the smuggling of people across national borders has become a lucrative extra-legal activity, as well as the extremely dark side, people-trafficking, especially of women who may be enslaved typically as prostitutes. Types of smuggling Goods Much smuggling occurs when enterprising merchants attempt to supply demand for a good or service that is illegal or heavily taxed. As a result, illegal drug trafficking, and the smuggling of weapons (illegal arms trade), as well as the historical staples of smuggling, alcohol (rum-running) and tobacco, are widespread. As the smuggler faces significant risk of civil and criminal penalties if caught with contraband, smugglers are able to impose a significant price premium on smuggled goods. The profits involved in smuggling goods appear to be extensive. The iron law of prohibition dictates that greater enforcement results in more potent alcohol and drugs being smuggled. Profits also derive from avoiding taxes or levies on imported goods. For example, a smuggler might purchase a large quantity of cigarettes in a place with low taxes and smuggle them into a place with higher taxes, where they can be sold at a far higher margin than would otherwise be possible. It has been reported that smuggling one truckload of cigarettes within the United States can lead to a profit of US$2 million. People smuggling With regard to people smuggling, a distinction can be made between people smuggling as a service to those
