Poppy flowers are
so pretty, and they are everywhere. When you look at them, you would never
think that such things like opium is made out them. Opium has been playing a
big role in history in humanity. From the Opium War between China and UK, to
the Civil War in the US, opium had significant influence. The Opium War was
definitely was one of the worst things that happened to China, and the fault kind
of goes to opium. In the Qing Dynasty, the British people brought the opium to
China, and started huge trading and merchandising opium. People started to get
lazy, including a lot of royal members, just wanted to smoke pipes all day and
not work. This soon became a real problem for the society until the government
attempted to stop the trading and importing of opium. That was when the Brits
got angry and used opium as an excuse and started to fire bombs to China,
eventually won the war and we paid Hongkong and tons of money for
“compensation”.
Opium is used as a
painkiller in the ancient times, and it gives the user a drowsiness effect. Not
long after, people have started to use opium as recreational use. They give you
a relaxed sensation and hallucination, but the biggest side effect is the
hopeless addiction and the withdrawal effect is extremely severe. So what
chemical is responsible for this stuff?
The opium resin
contains two major alkaloids, the phenanthrenes and benzylisoquinolines (papaverine). Morphine,
codeine and heroine are all opiate derivatives that are present in opium. Morphine and codeine are actually utilized in
the modern society as potent opiate analgesic drugs that relieve severe pain.
Because their adverse affect, the drugs are prescription only. Especially morphine,
is present in widely marketed drugs like Avinza and Kadian, etc. The side effects are more or less those of opium.
Morphine acts on the myenteric plexus (part of the enteric nervous system) in the intestinal
tract, thereby reducing gut motility, causing constipation. In addition, the
addiction is very serious, and can lead to the condition similar to heroin
addiction if not taken-in properly. Also, the withdrawal effects and addiction lead
to great pain, such as depression, anxiety, mood swings and all those kind of
bad things. Morphine, as a benzylisoquinoline alkaloid, the chemical structure
contains several carbon rings and the ring system has little conformational
flexibility (no isomers). Morphine can be made into codeine by methylation.
Actually, by modifying morphine, you could create more than 200 derivatives and
they all vary a little in functionality. Moreover, as we all know how bad heroin is and it doesn’t do anything
good.
Opium has two
sides, one to help people for pain relief, one to harm people and countries.
Just like thalidomide, with its adverse influence on the previous users but now
used to treat cancer. There are just good things you can find about them.
