China ‘can transform the war on drugs’ with ultra-fast portable detector

China ‘can transform the war on drugs’ with ultra-fast portable detector

China has deployed a portable drug detector at some border checkpoints that can radically improve the speed and accuracy of narcotics testing.

Visitors to the country, where drug trafficking can result in the death penalty, can have their luggage or personal belongings poked with a needle by security staff.

The sample collected at the needle’s tip, which is almost invisible to the naked eye, is analysed by a portable device about the size of a home printer. The device can detect the presence of narcotics in quantities as small as 50 picograms – or about the weight of two human red blood cells. A picogram is one trillionth of a gram.

The technology is helping law enforcers identify in three seconds nearly 40 types of drugs in circulation, as well as previously unknown composites made of several types of ingredients.

In most countries, such work is normally carried out in a well-equipped laboratory, taking hours or even days, but the new equipment could enable law enforcers to perform trace analysis anywhere.

Professor Li Haiyang, a researcher from the Dalian Institute of Chemical Physics who has led the development of the detector, said drug trafficking networks around the globe would soon “feel a pinch”.

From remote towns near the border between China and Myanmar to applications in countries around the world, “the detector can change the war on drugs”, he said.

At present, the decision over whether to question or search a suspect depends heavily on the experience of anti-drug police. An examination is slow and intrusive, often causing long delays.

The new equipment can assess people with minimal disruption, according to Li. The sampling needle is extremely small, with a tip only a few micrometers in diameter. The hole it leaves on material it has pierced will be barely noticeable.

The detector can be packed in a suitcase and its energy comes from a rechargeable lithium battery.

The unprecedented sensitivity means that a person who has had recent contact with drugs – even molecules of a substance on clothes or accessories – can trigger an alert.

The faster police can determine the nature and chemical composition of a drug, the sooner they can find members of a drug ring, Li said.

Using the equipment, authorities in cities including Yuxi, Dehong, Tengchong, Baoshan and Mojiang, in the southwestern province of Yunnan – which borders Myanmar – have seized drugs including opium, marijuana and fentanyl, according to a statement by the Chinese Academy of Sciences on Tuesday.

Li said the detector could become standard in public transport hubs. “Mass production is on the way,” he said. “We are working with several companies, and large-scale deployment is possible in a few years.”

A detailed description of the device was recently published in the journal Analytical Chemistry. It said the detector used a powerful flashlight to heat up a sample, generating a temperature of up to 500 degrees Celsius (932 Fahrenheit) in 2.5 seconds, causing it to vaporise and allowing the gas to be analysed quickly.

The need to heat substances with different melting points quickly but without damaging them required the researchers to test different drugs to determine the optimal range of light frequencies.

“It took us more than five years to solve these problems,” Li said.

Chinese law enforcers confiscated 67.9 tonnes of drugs last year, with nearly 140,000 suspects being arrested. More than 2.4 million Chinese citizens used drugs last year, according to government statistics.

Export all Drug Addicts to Goa - The Drug Paradise

The Success of the Goan Fenee Drug Model is that the price of coke has fallen by 50% to Rs 3500/gm while the price of diesel/food/beer/sex has gone up – May Moses and Jesus bless Dudu,Atila and the Nigerians (Drugs and Beer is proof that the Lord wants you to be happy at the lowest cost)

Inflation is Up,Gold is Up and Coke is down ! It is the magic of Goa Economics !dindooohindoo

The pathetic state of affairs is such – that the 10 Types of Drugs are now available in the Schools of the Goan Konkani Ghatis – which is the worth of the Goan Chofr Matka Chaddhi Chor Police

https://www. heraldgoa.in/Goa-News/Goa- News/Opposition-floors- government-on-drug- availability-in-schools/ 127242.html

All the Goan Students in Schools are inspired by Apple co-founder Steve Jobs,who took LSD on a trip to Goa as a Backpacker,.ALL GOANS TREAT STEVE JOBS AS THEIR ROLE MODEL AND THEY DO NOT EAT APPLES – THEY SNORT COKE AND DRINK FENEE!

There is 1 more Role Model for the Goan Students.His name is DUDU. I am DUDU from Israel and I do NOT drink doodoo !

He set up a company called Dudu Division Import Export Private Limited.He came to Goan Fenee Land on a Business Visa for Drug Pushing
He even challenged an order of deportation and a “Leave India Notice”,of the limpet GOI and won ! He won !

Let us meet Mr Atala – the Israeli Drug Kingin in Goa Fenee Land and his views on the Goan Police (who jumped bail and escaped)

https://www.youtube. com/watch?v=47uTOPRsHnc& feature=youtu.be

Mr Dudu – is an Israeli Drug Dealer with the following USP ( and who was acquitted by the Court as the Polixe bungled the case)

THE GOA POLICE IS KNOWN AS A DRUG PUSHER AND A CHOR MATKA CHADHI CHOR POLICE

Parrikar on ANC Staff

· “The Goa police are ashamed of (the act of) a police sub-inspector and four constables of falsely implicating David Driham, an Israeli national living at Anjuna,” a newsletter released by the office of Chief Minister Manohar Parrikar said.

o In the newsletter, there is a separate column mentioning that the department is ashamed of police sub inspector Sunil Guddlar and four constables, currently in judicial custody after being arrested by the Central Bureau of Investigation, for planting drugs in the house of Dudu at Anjuna in 2010, following which he was arrested.

· As per Parrikar, the Goan Police helped Atala, the Israeli ,get bail and then helped him jump bail and then brought him from Peru (all drama by the Goan Police) – and used a police informer to be the witness for Atala ! (when Ravi Naik – also a co-accused,was the Home Minister)

· The same is also stated in the “House Committee Report on Drugs”

· https://www. outlookindia.com/newswire/ story/goa-police-helped-atala- get-bail-parrikar/717090

CM of Goa on Ashish Shirodkar

“Ashish Shirodkar is getting royal treatment in the crime branch, which is investigating the entire nexus. If the investigating officer continues to avoid arresting him, he himself should be jailed for connivance,” leader of Opposition Manohar Parrikar said today.

Parrikar said there is a strict guideline by the Supreme court that the inquiry against any police officer should not be conducted by the state police themselves.

“The case should have been handed over to some other agency which can conduct impartial inquiry into it,” the BJP leader added.

“There must have been more than five policemen involved in the entire offence. There will be 20 to 25 policemen in the nexus,” he alleged.

· After 4 years of Investigation, the CBI dropped the drugs charges on Atala and the 6 officers of the police, and instead focused on forgery by some police officers

Statements of the Panaji bench of the Bombay high court.

· The court observed that the police were shielding the political patrons of the drug trade “because more skeletons may tumble out from the cupboard of the police-drug dealers nexus… Is there anyone in Goa, not connected with the police, drug dealers and politicians, who does not believe that this nexus exists only because of political patronage?”

· Justice N.A. Britto, in his order issued in June this year, had also said that the investigating team led by Salgaonkar was unwilling to get to the bottom of the police- politician-drug dealer nexus, in which seven policemen have already been arrested.
o DYSP SALGAONCAR was later awarded the CMs Gold Medal on Goa Liberation Day
Mahatma Gandhi

· As per a “sting operation and sworn testimony” – Sunil Guddler of the ANC, referred to Ex-SP ANC – Veenu Bansal, as ”Mahatma Gandhi”, and, as the “man who took” bribes, “via the conduit” of Sunil Guddler of the ANC
