Inside the poppy plant are things like morphine, codeine, poppy alkaloids, etc. Morphine is one of the reasons why poppies have medicinal value and is a psychotropic drug.

Poppy is certainly dependent and addictive. So here's an explanation of why it's addictive. The main thing is the effect of morphine. Morphine mainly acts on the opioid receptors inside the brain. Morphine has an analgesic effect and this is because of the opioid receptors. So morphine can inhibit breathing, shrink the pupils, slow down the bowel movement, but also to get pleasure, let a person feel pleasure, etc., the brain directly feel is eaten after the morphine is very pleasant, so the brain will spend a small cost to pursue all kinds of pleasure, which is the brain quickly to achieve the purpose of a pathway, the brain will guide you to go after this kind of pleasure, which is addictive.

Morphine is also very effective in treating diarrhea, and one of the side effects of opium use is constipation. This is because there are opioid receptors in the intestines as well. Morphine-based drugs make the opioid receptors in the intestines act to inhibit intestinal peristalsis, promote the absorption of water, electrolytes, glucose, to achieve the effect of stopping diarrhea.

Some of the food will be added, but the content is not high, but it is enough to stimulate. Why is delicious food delicious? The color and flavor can bring you a pleasant feeling, once eaten can give you pleasure, the brain will feel that this is the food. And after adding morphine to the food, can directly produce pleasure, and because the content is not very high, the brain can not recognize this is the pleasure of morphine or the food itself to bring pleasure, so it will do a simple addition, the pleasure of the morphine in the food to produce pleasure in the brain, the food will be more delicious.

Any kind of food with poppy, I think after eating it, your brain comes to the same result, the brain doesn't recognize the poppy directly, so it counts the pleasure in the taste of the food, and it's more pleasurable to eat it, and the food tastes better, and it's recognized as such in the future.
