Effectiveness of Heroin-Assisted Treatment Compared With Methadone Maintenance

(Effectiveness of Heroin-Assisted Treatment Compared With Methadone Maintenance) "Diacetylmorphine was found to be a dominant strategy over methadone maintenance treatment in each time horizon studied (Table 2). Over a lifetime horizon, people in the methadone cohort lived 14.54 years on average following entry into the model, spending 8.79 years (60% of their remaining life) in treatment and 5.52 years in relapse. They accumulated 7.46 discounted QALYs and generated a societal cost of $1.14 million.

Effectiveness of Naloxone Against Opiate Overdoses

(Effectiveness of Naloxone Against Opiate Overdoses) "Treatment with naloxone can reverse respiratory failure within a few minutes (Darke and Hall, 1997; Physician’s Desk Reference, 2000). Naloxone is an opiate antagonist, and is thought to displace heroin at the Mu2 receptors. Physicians and emergency personnel treat patients suspected of heroin overdose by administering an initial dose of naloxone parenterally.

Opioid Overdose Deaths in the US, 1999-2005

(Opioid Overdose Deaths in the US, 1999-2005) "There can be no doubt, however, that fatal opioid overdose, long a chronic health problem in the United States, is now a rapidly growing one.71 National surveillance data suggest that almost 83,000 Americans died from this form of overdose between 1999 to 2005, with over 16,000 fatalities in 2005 alone.72 Opioid overdose death has seen a sharp increase over the last decade, especially in the category of overdose from prescription medications.73 Because of gaps in the surveillance system, t

Heroin Toxicity or Overdose

(Heroin Toxicity or Overdose) "The main toxic effect is decreased respiratory rate and depth, which can progress to apnea. Other complications (eg, pulmonary edema, which usually develops within minutes to a few hours after opioid overdose) and death result primarily from hypoxia. Pupils are miotic. Delirium, hypotension, bradycardia, decreased body temperature, and urinary retention may also occur.
"Normeperidine, a metabolite of meperidine, accumulates with repeated use (including therapeutic); it stimulates the CNS and may cause seizure activity."

Pain Patients in Methadone Treatment

(Pain Patients in Methadone Treatment) "Pain was very prevalent in representative samples of 2 distinct populations with chemical dependency, and chronic severe pain was experienced by a substantial minority of both groups. Methadone patients differed from patients recently admitted to a residential treatment center in numerous ways and had a significantly higher prevalence of chronic pain (37% vs. 24%).

Undertreated Chronic Pain and Development of Substance Dependence

(Undertreated Chronic Pain and Development of Substance Dependence) "In our study, there was greater evidence for an association between substance use and chronic pain among inpatients than among MMTP [Methadone Maintenance Treatment Program] patients. Among inpatients, there were significant bivariate relationships between chronic pain and pain as a reason for first using drugs, multiple drug use, and drug craving. In the multivariate analysis, only drug craving remained significantly associated with chronic pain.

Estimated Global Opium Production, 2012

(Estimated Global Opium Production, 2012) "Afghanistan maintained its position as the lead producer and cultivator of opium globally. With a global total of over 236,000 hectares under cultivation, illicit cultivation of opium poppy reached peak levels in 2012, surpassing the 10-year high recorded in 2007. This was mainly the result of increases in Afghanistan and Myanmar (the two main producers).
