"Laughing Q", whose scientific name is nitrous oxide, is a colorless and sweet chemical gas, which is widely used in industrial and medical uses, and has the advantages of high comfort and fast onset in the field of medical anesthesia, and is especially widely used in pediatric dentistry. In the food industry, it is also widely used as a foaming agent and sealant for making cream.

The reason why it is called "laughing Q" is because when nitrous oxide with high purity is inhaled directly into the body, the person who smokes it will involuntarily laugh and have a brief state of excitement.

After inhaling a large amount of "laughing Q", people will unconsciously giggle, react slowly to the outside world, lack pain sense, and feel euphoria. Therefore, many people use it as a substitute for D products and become victims of "laughing Q".

Although China has not included "Xiao Q" in the D product catalog, it does not mean that it is not very harmful. Smoking "laughing Q" is very addictive, and it is extremely harmful to the human body after smoking, and it is easy for people to become dependent, and its harm is no less than that of D product.

A large amount of inhalation at one time makes the human body unable to obtain enough oxygen to maintain the normal needs of the human body, which can lead to ischemia and hypoxia, coma and even death.

Therefore, it is obvious that it is impossible to cause this level of respiratory injury, or even cause respiratory failure, resulting in suffocation and death.

What exactly is this harmful gas? Where are the other companions who smoked with him?

Has this happened to your companions?

These are all questions that must be considered at the moment.

"How is the patient doing now? Can you accept our inquiry? "I made up my mind and asked the attending physician in front of me.

The attending physician pondered for a moment and slowly spoke: "The patient is now awake, but his respiratory tract is seriously injured, and we have used endotracheal intubation, with ventilator-assisted treatment, and he has no way to speak now. ”

After a while, the attending physician added, "But you can ask him to answer your questions with some gestures." ”

This is a case involving D, and the attending physician is very aware of the patient's current situation, and he also understands the nature of our police investigation at the hospital.

"Okay, thanks." I nodded, ready to enter the room to investigate him.

We were about to leave, but the attending physician hurriedly stopped us and added: "Ten minutes, the patient's vital signs are still relatively weak, and his life will be in danger at any time, and he needs to rest." ”

"Okay, we'll take the time." I said yes to the attending physician and pushed the door open and walked into the room.

It was a single-occupancy unit, second only to the hospital's intensive care unit, with a boy lying on the bed, and various medical equipment running, maintaining his vital signs.

The boy's parents were being questioned by the police in the hallway, and there were only two police officers in the ward.

Li Meng and I walked to the hospital bed and said softly: "We are criminal police, come to investigate the situation with you, you don't have to answer, we will ask you questions, if it is positive, you can move your left hand, if it is negative, you can move your right hand." ”

The boy slowly opened his eyes and looked at us, his left index finger moving slightly.

After receiving the boy's reply, we officially began to investigate: "Did you gather a crowd to smoke laughter?" ”

The boy's left index finger continued to move.

"How many of you have smoked laughs?" I asked again.

The boy slowly raised four fingers and replied to us, there were four of them.

"Did you smoke it in a hotel room?" I continued.

The boy's left hand moved.

"Hotel or hostel? Hotel? "I made up my mind and was ready to ask for a detailed address.

The boy's left hand didn't move, and the fingertips of his right hand tapped the sheet slightly.

"Inn?" I looked at him and confirmed to him.

The tip of the boy's left finger moved, affirming it.

Next, we're going to ask them in detail where the hotel where they smoke.

Li Meng turned on his phone, transferred to the map of Renxi City, and asked the boy for the names of all the inns one by one.

Each time he asked, the boy's right hand tapped the sheets lightly, and after asking more than a dozen questions in succession, the boy's left hand finally moved.

The name of this inn is "Jinbo Hotel".

After determining the location of the hotel, Li Meng and I quickly turned around and went out and told Gong Haonan, the captain of the criminal police, about the investigation.

Although the boy said that they were together and smoked Xiao Q, judging from the boy's symptoms, the Xiao Q they smoked was suspicious and suspected to be some kind of harmful gas.

Gong Haonan immediately took the criminal police, and at the same time contacted the anti-narcotics police of the anti-narcotics brigade and cooperated with us to go to the Jinbo Hotel to investigate the situation.

If there is really some kind of harmful gas in the room, the anti-narcotics police of the anti-narcotics brigade will provide us with gas masks to ensure our safety.

In the car, Gong Haonan told us about the situation investigated from the boy's parents.

"Today, on Sunday, in the afternoon, the boy was invited to the hotel to have a laughing Q with three social friends. The boy said that he did not smoke, he was watching his social friends smoking, he smelled a somewhat pungent rancid smell, and he was a little scared, so he never smoked, and after staying in the room for a while, he went home. Unexpectedly, not long after returning home, he felt that he had some difficulty breathing, and after telling his parents the details, his parents rushed him to the hospital. Gong Haonan said in a deep voice.

"Therefore, he did not smoke, and he had such a serious illness, so the other three people who smoked must be very dangerous now." After listening to Gong Haonan's words, my heart suddenly tightened, and I became a little worried.

"If they were sick in the hotel room, the situation must be very dangerous now, and it is very likely to ......," Li Meng said, not continuing his words.

Because we all know the result.

But now it's like Schrödinger's room, and if we don't open the door, we don't know what happens to the people inside.

When we arrived at the Jinbo Hotel, the anti-narcotics police of the anti-narcotics brigade had just arrived.

Walking into the hotel, we walked directly to the front desk: "From the Public Security Bureau, where is your boss?" ”

After Gong Haonan showed his police ID, he asked directly.

There was a middle-aged man sitting in the front desk, he stood up tremblingly, and said weakly: "I...... I'm the boss. ”

"This afternoon, four children opened a room here, which room is it?" Gong Haonan immediately asked.

"Four kids?" The innkeeper was stunned for a moment, then looked at us in a daze.

"Hurry up!" Gong Haonan raised his voice and shouted directly.

The matter is urgent, human lives are at stake, and the people in the room are likely to have been poisoned and died.

"In ...... Room 332......" The innkeeper was stunned and hurriedly said.

"Give me the room key!"

As soon as the innkeeper's voice fell, Gong Haonan immediately shouted.
