abuse and overdose is a public health concern. Although suburban healthcare providers may have more resources to address drug addiction, abuse, and overdose, preconceived ideas about suburban lifestyles may prevent them from providing proper treatment to patients. Considering the increasing incidence of drug abuse in suburban environments, the contextual factors that affect certain demographics must also be considered to better understand the prevalence of drug abuse in suburbs; for example, adolescents and their relationship with social groups in school and other socializing forces that occur as a result of suburbanization impact drug abuse incidence. Economic impacts The economic impacts of suburbanization have become very evident since the trend began in the 1950s. Changes in infrastructure, industry, real estate development costs, fiscal policies, and diversity of cities have been easily apparent, as "making it to the suburbs," mainly in order to own a home and escape the chaos of urban centers, have become the goals of many American citizens. These impacts have many benefits as well as side effects and are becoming increasingly important in the planning and revitalization of modern cities. Impact on urban industry The days of industry dominating the urban cores of cities are diminishing as population decentralization of urban centers increases. Companies increasingly look to build industrial parks in less populated areas, largely for more modern buildings and ample parking, as well as to appease the popular desire to work in less congested areas. Government economic policies that provide incentives for companies to build new structures and lack of incentives to build on Brownfield land also contribute to the flight of industrial development from major cities to surrounding suburban areas. As suburban industrial development becomes increasingly more profitable, it becomes less financially attractive to build in high-density areas. Another impact of industry leaving the city is the reduction of buffer zones separating metropolitan areas, industrial parks and surrounding suburban residential areas. As this land becomes more economically relevant, the value of such properties very often increases, causing many undeveloped landowners to sell their land. Consequences on infrastructure As America continues to sprawl, the cost of the required water lines, sewer lines, and roads could cost more than $21,000 per residential and non-residential development unit, costing the American government $1.12 trillion between 2005 and 2030. Along with the costs of infrastructure, existing infrastructure suffers, as most of the government's money that is dedicated to improving infrastructure goes to
