1996 and 2011, there have been large fluctuations in drug usage, with the most recent trend being an overall decline in illicit drug use between 2007 and 2011. However, between 2010 and 2014, hospitalizations related to addictions increased by 89% at St. Paul's Hospital. According to a 2008 survey of greater DTES area SROs, tenants who used drugs estimated the cost of their habits at $30 per day, on average. Some spend hundreds of dollars per day on drugs.
