When the three words ephedrine came out, I was completely stunned if I didn't understand pharmacology.

"What happened to ephedrine?" Captain Dahai said.

"There are only a few drugs that can extract ephedrine, all of which are strictly controlled by the state. It's even more difficult for ordinary people to get it, so I think the problem lies in the source. Usu said.

Wu Su seemed to have said something, Chen Hao thought for a while and said, "Start with the raw materials from a different angle?" ”

Wusu smiled and said: "That's what it means, but I know that the state has a deep drug management in first-tier cities, but second- and third-tier cities are different." Maybe there is a loophole in this that allows criminals to get ephedrine to make yellow ice, so as long as you find a loophole and check it out, you can find the drug production point. ”

"What is the raw material for making ephedrine?" Captain Dahai said.

"The solvent method, the distillation method and the ion exchange resin method are three methods, and the three methods correspond to Western medicine and traditional Chinese medicine and direct extraction from ephedra grass respectively. Xiamen should not be suitable for the cultivation of ephedra, so there is only traditional Chinese medicine and Western medicine left. These things depend on whether the control is strict or not, and if you are not strict, you can get them from Western medicines like amoxicillin, which you should have all heard of. Usu said.

Captain Dahai nodded and raised his arm, looking ready to make a phone call.

"Captain? What is this for? I said puzzled.

"Call and ask the anti-narcotics director." Captain Dahai said, pressing the hands-free.

As soon as the music remembered to reach everyone's ears, it was immediately picked up.

"Captain Pang? What are you looking for me? The other party said.

"How is the drug control in Xiamen?" Captain Dahai said.

"It's a strict kind, why are you starting to suspect hospitals or pharmacies?" The other party said.

"That's exactly what I mean, but I'm not very clear about this kind of control in Xiamen." Usu said.

"Well, then I'll say it once, all prescription drugs are controlled here. Originally, three months ago, we could still rely on our ID card to buy one box a day, but after Huang Bing appeared, we applied to change the system. For these three months, there must be a doctor's certificate from a third-class hospital or above, and the purchaser must also state the company where he works when he or she issues a doctor's certificate. Otherwise, pharmacies will not sell them privately, and the management system of large hospitals will be stricter. Anyway, the drugs with or can refine the ingredients of yellow ice, we have all firmly controlled them for the past three months. But even so, Huang Bing still kept banning. The other party said.

"So can't you rule out that there is a problem with the hospital or pharmacy?" Chen Hao said.

"Let's be honest, we've thought about this before. We have checked here, and there are no problems in several tertiary hospitals. It is difficult to check the pharmacy, but the original annual review of the pharmacy was changed to once a month. Even with such an inventory, the drug loss data of pharmacies is zero, and I want to say that the circulation of yellow ice on the market is probably three to four times that of this type of drug. The other party said.

"What do you mean by that?" I was puzzled and said,

"It's that the pharmacies and hospitals in Xiamen together use at least three or four times as many of these drugs to be on par with the yellow ice on the market, and that's what we find unbelievable. With such purity and price, we can also control the supply. This is a tough battle, otherwise it wouldn't have alarmed the superiors. The other party said.

"Does this mean that these yellow ice are not extracted from medicine?" Chen Hao thought about it and said. 8)
