The ten most deadly drugs

From Time, an article by Alice Park about deadly drugs:

Overdose deaths are up over twenty percent in four years. Here are the top causes:

From 2010 to 2014, the number of people dying from drug overdoses in the US increased by 23%, according to data from the National Vital Statistics System, which tracks cause of death from death certificates. The top ten drugs responsible fell into one of three main categories: opioids (which includes heroin, painkillers like oxycodone, hydrocodone, morphine, and fentanyl as well as methadone, which is used to treat heroin addiction); benzodiazapines (like alprazolam, which is used to treat anxiety, often under the brand name Xanax, as well as other drugs that treat depression, insomnia, and nausea, among other conditions); and stimulants like cocaine and methamphetamine. 

In order, for 2014, the top ten drugs involved in lethal overdoses were:

• Heroin
• Cocaine
• Oxycodone
• Alprazolam
• Fentanyl
• Morphine
• Methamphetamine
• Methadone
• Hydrocodone
• Diazepam

Rico says only the families of the dead are likely to care, but he still advocates dropping bags of pure heroin on urban street corners to remove the problem...
