"Trends in Adolescent Treatment Admissions for Marijuana in the United States, 2008–2017"

126027997_3443829359064341_5275240354102147479_n-768x1005The title of this post is the title of this notable new publication from the CDC's Preventing Chronic Disease series authored by Jeremy Mennis.  (Hat tip Marijuana Moment.)  Here are the highlights and action sections that conclude the piece (with some sentences highlighted):


The map, visually dominated by blue tones, clearly shows that adolescent treatment admissions for marijuana declined in most of states.  The mean annual admissions rate for all states declined over the study period by nearly half, from 60 (admissions per 10,000 adolescents) in 2008 to 31 in 2017, with state admissions rate slopes ranging from −0.42 to 0.19 (median = –0.28).  State admissions rates in 2008 ranged from fewer than 1 to 218 (median = 52); in 2017 they ranged from fewer than 1 to 167 (median = 21). Admissions rates increased over the study period in only 7 states, 6 of which (excepting North Dakota) have relatively low mean admissions rates (states colored lighter orange).  Low mean admissions rates tend to occur in a loose band extending from the Southwest through the South, Appalachia, and into parts of New England.  All 12 states in the high mean admissions rate class sustained admissions declines, with 10 of those states having declines in the steepest category (states colored darkest blue).  Consistent with prior research on medical marijuana and adolescent marijuana use (12), medical legalization status does not appear to correspond to treatment admission trends.  Notably, however, 7 of 8 states with recreational legalization during the study period fall into the class with the steepest level of admissions decline.


To our knowledge, this map is the first to illustrate state level trends in adolescent treatment admissions for marijuana, and the trends depicted can inform public health responses to changing marijuana laws.  Possible causes for the overall decline, and variations among states, in admissions trends include changes in attitudes toward marijuana, as well as differences among states in marijuana use and incidence of CUD, as well as in socioeconomic status, treatment availability, and health insurance (5).  Whatever the causes of the observed patterns, however, this research suggests that a precipitous national decline in adolescent treatment admissions, particularly in states legalizing recreational marijuana use, is occurring simultaneously with a period of increasing permissiveness, decreasing perception of harm, and increasing adult use, regarding marijuana (4,13).  These trends indicate the need for sustained vigilance in the prevention and treatment of youth CUD during this period of expanding marijuana legalization.
