Homelessness in America's cities remains a growing problem. The homeless today face the same challenges as in years past: poverty, tenuous or no ties to family and friends, physical and mental health issues, and substance abuse. Compared to the 1950s to 1970s, more homeless are now sleeping on city streets versus in shelters or single room hotels. Homelessness rates are affected by economic trends, lack of equitable and inclusive healthcare and housing, decline in public assistance programs, and natural and man-made disasters. This collection of essays covers case studies, innovations, practices and policies of municipalities coping with homelessness in the 21st century.

Syringe exchange programs and safe injection services are outside-the-box interventions increasingly being used by governments, nonprofits and citizens to address dire issues percolating in tandem with America's burgeoning opioid epidemic. People who inject drugs (PWID)-almost a million Americans annually-commonly use painkillers such as heroin and fentanyl, as well as methamphetamine, benzodiazepines, barbiturates and cocaine. Yet the users themselves are often obscured or marginalized by the bigger picture. This collection of essays covers policies and practices aimed at preventing both opioid-related deaths and related infections of hepatitis and HIV.

The public services and care being provided to our veteran citizens are rapidly changing due to the increasing number of veterans that live in our cities. There are more veteran citizens now living in America than ever before, and the veteran population is becoming ever more diverse. For this reason, cities throughout our nation are expanding their public services in scope and scale, as well as enhancing the quality of existing services. This volume documents these rapid developments in order to help our veteran citizens and supporting communities understand the evolving, dynamic, and innovative services and care that are increasingly available to them.

The legalization of marijuana has spread rapidly throughout the US, from just a handful of states ten years ago to now more than half, as well as the nation's capital. In Canada, it is legal to use and distribute nationally. Thousands of cities and towns are following suit. Legalization seems to be a win-win - people who use cannabis for health and recreation are served, business is brisk, and many governments welcome the much-needed boost in tax revenue. But not everyone thinks so. The rapid pace of legalization has spurred debate among citizens, cities, states and the federal government. This collection of essays explains the benefits and concerns, the policies and actions, and the future of this controversial issue.
