Fatal doses of heroin, fentanyl and carfentanil
|The world hardly needs a more efficient way to make fentanyl. The last thing the world needs is a list of analogs and the procedures to make them so strong they make fentanyl look like bubble gum. Sadly a published paper gives us both.|
|But even carfentanil isn't even the most potent fentanyl analog out there. That 'honor' belongs to a derivative called ohmefentanyl. Two simple modifications ... the addition of one methyl group and one hydroxyl group (blue circles)— makes the molecule 6.3 times more potent than carfentanil, 126 times more than fentanyl, and 6,300 times more than morphine.|
The estimated lethal dose of ohmefentanyl is 0.16 micrograms, which means that one poppy seed's worth (300 micrograms) of ohmefentanyl is enough to kill 1900 people. One ounce (28 grams, 28,000,000 micrograms) would be enough to kill 175 million people.
