In fact, poppy was found in the late Tang Dynasty. It was recorded in Tang Dynasty poetry, and poppy seeds were also unearthed in archaeology, mainly on the Silk Road west of Chang'an. By the ninth century, there were records of planting people in Hanzhong, Chengdu and other places.

During the Song Dynasty, opium had been recorded in many places, such as Zhou Zizhi wrote two articles "Growing Poppies" and "Poppy Will Become", but she only treated opium as a tonic to cure diseases.

However, extracting opium from poppy is a technology that has only been established since the Ming Dynasty.

The medicinal value of opium is recorded in medical books since the Song Dynasty and is regarded as a good medicine for treating dysentery and other diseases.

During the Yuan Dynasty, traditional Chinese medicine had a preliminary understanding of the huge side effects of poppy, and it is recommended to use it with caution. For example, the famous doctor Zhu Zhenheng pointed out: "Now people who have weak and coughing should use mostly millet shells to stop diligently; those who are damp and heat discharged should use it to stop astringent. Although the effect of stopping the disease is urgent, killing people is like a sword, so it is better to be warned." However, people did not remember Zhu's advice. During the Yuan Dynasty, some people had already started taking opium.

The opium consumed by the Yuan Dynasty was not made from China, but was plundered from the war to conquer India and other places. Opium, as a trophy, was very popular at the time.

It was not until the Ming Dynasty that China gradually understood the production and production of opium. Li Shizhen's "Compendium of Materia Medica" recorded the method of harvesting opium at that time. According to the "Ming Hui Dian", Southeast Asia's Siam, Java, Bang Gelai and other places produced many opium, and were often contributed to the Ming emperors as "tribute" medicinal materials. For example, Thailand paid 300 kilograms of opium at one time. Until the Chenghua period, the import of opium was still quite limited, so the price of opium on the market was expensive and could be compared with gold.

As a later generation, Zhang Nan hated this thing deeply. For the country, the large-scale import of opium caused the outflow of silver in China to reach 6 million taels every year, causing a serious silver shortage in China, causing high silver and low money, resulting in inflation, exhausting the Qing government's finances and emptying the national treasury. Opium trade seriously corrupted social trends, and at the same time destroyed social productivity, causing industrial and commercial depression and decline in the southeast coastal areas.

For people, the late Qing Dynasty was a phenomenon of sucking from princes and ministers to civilians, and it was a national phenomenon, and it greatly reduced the physical fitness of the Chinese people. Even some people in the army were sucked, which caused the overall combat effectiveness of the army, weak physically, and even made them lose their combat capabilities.

Therefore, Zhang Nan hated this kind of thing deeply. Nothing is more terrifying than drugs. He may be able to fight to the last war. Even if he is defeated, as long as he has life, he will be left without worrying about burning firewood.

But this kind of thing slowly destroys the entire country, just like a thousand-mile dike that collapses into an ant hole. At first, there is no big problem, but when you come back to your senses, the losses caused are already irreversible.

"If the emperor insists on making an analogy of this thing, it's almost the same as the Five Stones Sphere, but the harm of this is much clearer than that of Five Stones Sphere." Zhang Nan thought for a while and helped Comrade Li Er make an analogy.

Although Wushisan is a relatively low addictive thing, it is also considered a non-mainstream drug. After absorbing Wushisan, you will be very happy. You will be ambitious and spilled your passion. The seven sages of the bamboo forest in the Wei and Jin Dynasties like to absorb it. When they are most toxic, they will think of a lot and then cry. Ruan Ji once sucked Wushisan and wrote 87 poems overnight.

In addition to the fact that only nobles could absorb Wushisan, which caused a wrong trend, another more important reason for sucking Wushisan in ancient China was its aphrodisiac effect.

Sun Simiao once said: "If you have greed for five stones, you can seek happiness in the room."

So it can be seen that this thing is a combination of drug addiction and sex addiction, so it is so popular among the upper class.

But opium is different. Not only is it highly addictive, but it is also much cheaper. After all, as long as there is a large amount of poppy, there will be a large amount of opium.

After hearing Zhang Nan say that Wushi San, Li Er stopped talking. In the past, Li Er also sucked this thing, and he was not addicted to it. After all, after sucking this thing, his combat effectiveness soared exponentially. However, since he learned that this thing is extremely harmful to the body, Comrade Li Er stopped touching it.

After all, compared with temporary pleasure, Comrade Li Er likes his life more.

"I understand. I will strictly limit this thing at that time." Li Er frowned.

"It is best to add this thing to the "Tang Law"." Zhang Nan said.

Zhang Nan knew that once drug abuse is leaked, it would not be something that ordinary people could control. Only the law can be controlled. And even if there is a law, even if there is a law, there will still be many people willing to take risks if they are involved in this thing.

"I think not only should this thing be added to the "Tang Law", but also severe punishment. If someone finds that he is sucking, he will be forced to quit drugs and be punished. If someone specifically provides these things he is sucking, he will be directly cracked." Zhang Nan said.

"Wouldn't such a punishment be too harsh?" Changsun Wuji frowned and said. After all, in Changsun Wuji's opinion, even sucking Wushi Powder is not a big deal. Why is this thing so serious?

"Tough? Not harsh at all. If there is no restriction, Lord Changsun will wait and see the large and small smoke shops opened in Chang'an City." Zhang Nan said with a sneer.

After all, in the era of opium smoking in later generations, there were many opium opium shops, and the empty eyes, numb expressions and thin bodies of the smokers in the tobacco shop left a deep impression on Zhang Nan.

"I have to consider this matter carefully." After all, adding things to "Tang Law" does not mean that you can add them. And Comrade Li Er still wants to use this thing for experiments first and then observe the results later.

After all, the other ones in the Heavenly Prison were used to do experiments except for the ending of being cut. Although it was cruel, it really existed. Apart from the death row prisoners, there were not too many eunuchs in the harem who tried medicine for the emperor.

After taking the pill, it would be fine if it was not poisonous. If the poisonous ones were poisoned, it would be poisoned to death. No one would care. So Comrade Li Er thought about whether this thing was as serious as Zhang Nan said, and then consider whether to add this thing to the "Tang Rule".

"Okay, let's follow me to see those rare beasts. I haven't seen these things before. I haven't left the house today, so I've gone to other places." Li Er quickly stopped mentioning this matter, but turned his head and walked towards the animals locked in the cage.
