Since the state legalized marijuana for recreational use, the Colorado Department of Public Health and Environment has issued a report on marijuana and health every two years. Colorado legalized recreational pot in 2012 to go into effect in 2014. This is the second health report. The report contains a huge amount of data. An executive summary appears on pages 1-6. The most startling data about the consequences of legalization are the number of marijuana-related hospitalizations that have occurred from 2000, the year Colorado legalized marijuana for medical use to September 2015, 21 months after recreational legalization began. A graph showing rates of these hospitalizations by age is pictured below. They are rates per 100,000 and have nearly doubled among adolescents and quintupled among young adults. A graph of the data broken down by race on page 291 of the report are equally stunning. Read report here.
