Morphine, formerly also called morphia, [14] is an opiate that is found naturally in opium, a dark brown resin produced by drying the latex of opium poppies (Papaver somniferum). It is mainly used as an analgesic (pain medication).
To the contrary, in rats, (+)-morphine acts as an antianalgesic and is approximately 71,000 times more potent as an antianalgesic than (−)-morphine is as an analgesic. [ 1 ] (+)-Morphine derives its antianalgesic effects by being a selective-agonist of the Toll-like receptor 4 (TLR4), which due to not binding to opioid receptors allows it to ...
Lewis bases and acids. Free base (freebase, free-base) is a descriptor for the neutral form of an amine commonly used in reference to illicit drugs. The amine is often an alkaloid, such as nicotine, cocaine, morphine, and ephedrine, or derivatives thereof.
Opioids work on opioid receptors in the brain and other organs to produce a variety of morphine-like effects, including pain relief. [2] [3] The terms 'opioid' and 'opiate' are sometimes used interchangeably, but the term 'opioid' is used to designate all substances, both natural and synthetic, that bind to opioid receptors in the brain.

N-piperidinyl-etonitazene (etonitazepipne) - 100 times more potent than morphine N-pyrrolidino protonitazene - found in drug seizures in Canada N-desethylisotonitazene - potency can be 20 more ...
The potent drug is also having a damaging impact in Canada. Last year the Canadian Centre on Substance Abuse warned that fentanyl-related deaths had increased in Canada's four largest provinces.
Carfentanil is 10,000 more times more potent than morphine and 100 times more potent than fentanyl, Tuell confirmed. "Even a small amount can be fatal, ... In a powder form, it can be inhaled.
It is a strong μ-receptor agonist that is 80–100 times more potent than morphine, and has a fast onset with a shorter duration of action than morphine due to redistribution from CNS location to fatty tissue. When it is used as a continual drug (e.g. transdermal patches, longer term use of IV fentanyl in ICU patients) its elimination half ...
