"During 2015, drug overdoses accounted for 52,404 U.S. deaths, including 33,091 (63.1%) that involved an opioid. There has been progress in preventing methadone deaths, and death rates declined by 9.1%. However, rates of deaths involving other opioids, specifically heroin and synthetic opioids other than methadone (likely driven primarily by illicitly manufactured fentanyl) (2,3), increased sharply overall and across many states."
"In 2014, alcohols, including ethanol and isopropyl alcohol, were involved in 15% of all drug overdose deaths and 17% of the drug overdose deaths that mentioned involvement of at least one specific drug. Table E shows the frequency of alcohol involvement among drug overdose deaths involving specific drugs.
" Alcohol involvement was mentioned in 12%–22% of the drug overdose deaths involving fentanyl, heroin, hydrocodone, morphine, oxycodone, alprazolam, diazepam, or cocaine.
"A key factor underlying the recent increases in rates of heroin use and overdose may be the low cost and high purity of heroin.45,46 The price in retail purchases has been lower than $600 per pure gram every year since 2001, with costs of $465 in 2012 and $552 in 2002, as compared with $1237 in 1992 and $2690 in 1982.45 A recent study showed that each $100 decrease in the price per pure gram of heroin resulted in a 2.9% increase in the number of hospitalizations for heroin overdose.46"
"In 2016, a total of 67,265 persons died of drug-induced causes in the United States (Tables 5, 6, 8, and I–1). This category includes deaths from poisoning and medical conditions caused by use of legal or illegal drugs, as well as deaths from poisoning due to medically prescribed and other drugs. It excludes deaths indirectly related to drug use, as well as newborn deaths due to the mother's drug use. (For a list of drug-induced causes, see Technical Notes.)
Cannabis and Mortality: "In summary, this study showed little, if any, effect of marijuana use on non-AIDS mortality in men and on total mortality in women. The increased risk of AIDS mortality in male marijuana users probably did not reflect a causal relationship, but most likely represented uncontrolled confounding by male homosexual behavior. The risk of mortality associated with marijuana use was lower than that associated with tobacco cigarette smoking."
Estimated Annual Number of Deaths Caused by Tobacco Use in the US: "The 2014 Surgeon General's report estimates that cigarette smoking causes more than 480,000 deaths each year in the United States.1 This widely cited estimate of the mortality burden of smoking may be an underestimate, because it considers deaths only from the 21 diseases that have been formally established as caused by smoking (12 types of cancer, 6 categories of cardiovascular disease, diabetes, chronic obstructive pulmonary disease [COPD], and pneumonia including influenza).
Increasing Involvement Of Benzodiazepines In Opioid Overdose Mortality In The US, 2011: "In 2011, 5,188 opioid-analgesic poisoning deaths also involved benzodiazepines (sedatives used to treat anxiety, insomnia, and seizures), up from 527 such deaths in 1999 (Figure 3). From 2006 through 2011, the number of opioid-analgesic poisoning deaths involving benzodiazepines increased 14% on average each year, while the number of opioid-analgesic poisoning deaths not involving benzodiazepines did not change significantly."
"In an analysis of death certificate data from 1999 to 2010, we found that states with medical cannabis laws had lower mean opioid analgesic overdose mortality rates compared with states without such laws. This finding persisted when excluding intentional overdose deaths (ie, suicide), suggesting that medical cannabis laws are associated with lower opioid analgesic overdose mortality among individuals using opioid analgesics for medical indications.
"Of the 36,667 drug overdose deaths with at least one mention of a specific drug, 52% mentioned only one specific drug (18,931 deaths), 26% mentioned two (9,351 deaths), 12% mentioned three (4,521 deaths), 6% mentioned four (2,041 deaths), and 5% mentioned five or more (1,823 deaths). Among drug overdose deaths with at least one mention of a specific drug, the average number of specific drugs mentioned was 1.9.
"Naloxone distribution was cost-effective in our base-case and all sensitivity analyses, with incremental costs per QALY [Quality-Adjusted Life-Year] gained much less than $50 000 (Table 2 and Appendix Figure 3, available at www.annals.org; see Appendix Table 3, available at www.annals.org, for detailed results of selected analyses). Cost-effectiveness was similar at starting ages of 21, 31, and 41 years; the greater QALY gains of younger persons were roughly matched by higher costs.
