Insite is the only legal supervised injection site in North America, located at 139 East Hastings Street, in the Downtown Eastside (DTES) neighbourhood of Vancouver, British Columbia. The DTES had 4700 chronic drug users in 2000 and has been considered to be the centre of an "injection drug epidemic". The site provides a safe and health-focused location for injection drug use, primarily heroin, cocaine, and morphine. The clinic does not supply any drugs. Medical staff are present to provide addiction treatment, mental health assistance, and first aid in the event of an overdose or wound. In 2009, the site recorded 276,178 visits (an average of 702 visits per day) by 5,447 unique users; 484 overdoses occurred with no fatalities, due to intervention by medical staff.Health Canada has provided $500,000 per year to operate the site, and the BC Ministry of Health contributed $1,200,000 to renovate the site and cover operating costs.

Una Vida is an archaeological site located in Chaco Canyon, San Juan County, New Mexico, United States. Its construction began around 900 AD and it is one of the three earliest Chacoan Anasazi great houses; it. Comprising at least two stories and 124 rooms, it shares an arc or D-shaped design with its contemporaries, Peñasco Blanco and Pueblo Bonito, but has a unique "dog leg" addition made necessary by topography. It is located in one of the canyon's major side drainages, near Gallo Wash, and was massively expanded after 930 AD.

The site is surrounded by Anasazi rock art and petroglyphs that depict human figures, solar signs, and geometric forms. It was first recorded in the mid-19th century by US military that were surveying the area of modern New Mexico.

Una Vida means "One Life" in the Spanish language.

Chaco Road is a network of roads (for travel and trade) which radiated from great house sites, such as Pueblo Bonito, Chetro Ketl and Una Vida. This road lead to smaller sites on the periphery of Chaco Canyon.
