Morphine
Morphine is an alkaloid obtained from the latex of opium poppy.
It is widely used as a potent painkiller.
Morphine binds to opioid receptors in the brain, spinal cord, and other parts of the body, reducing the perception of pain.
It is also used during surgical procedures and in palliative care.
However, prolonged use of morphine can lead to addiction and dependence.

Codeine
Codeine is another alkaloid derived from the opium poppy.
It is a mild analgesic and cough suppressant.
Codeine is less potent than morphine but has similar analgesic properties.
It is often used in combination with other medications for effective pain relief.
Codeine can also cause addiction and should be used with caution.

Opium Production
Opium production involves careful cultivation and harvesting of opium poppy plants.
The latex containing the alkaloids is extracted by making incisions on the seed pods.
The latex is then collected and allowed to dry, forming opium resin.
The resin can be further processed to extract morphine and other alkaloids.

Opioid Withdrawal Syndrome
Opioid withdrawal syndrome is a set of symptoms that occur when opioid use is stopped or reduced abruptly.
Common symptoms include restlessness, muscle and bone pain, insomnia, diarrhea, and nausea.
Withdrawal symptoms can be severe and vary in intensity depending on the duration and dosage of opioid use.
Medically supervised detoxification and withdrawal management programs are available to assist individuals in safely managing opioid withdrawal symptoms.
Behavioral therapy and medications can also be used to support recovery and reduce the likelihood of relapse.
