A lot of time and money goes into marijuana research. But what if I told you that you could take a nug of weed, place it in an espresso machine and extract cannabis ingredients in under one minute?
OK, that’s an oversimplified description. Still, it’s more or less what a team of researchers was able to accomplish in a recent experiment detailed in a manuscript due to be published in The International Journal of Pure and Applied Analytical Chemistry.

The team wanted to test whether espresso-based extraction—a novel and relatively inexpensive analytic method, raved about in scientific literature—could be applied to marijuana. And it turns out that it can!
You don’t need a fancy, $2,000 setup, either. For the experiment, the researchers used a Nespresso Essenza Manual XN2003 machine, which goes for about $300 on eBay. (It’s not currently available on Amazon, though—possibly because they’ve all been snatched up by the chemist community).
“The use of hard cap espresso machines has been recently proposed for analytical extractions due to its easy use, speed, availability and low price, providing efficient extraction of organic compounds from solid samples in few seconds,” the researchers wrote.
Seized cannabis provided by Unidad de Inspección de Farmacia y Control de Drogas del Área de Sanidad in Valencia, Spain, was inserted into the filter after a thorough cleaning. The hard cap espresso machine was used to extract three main ingredients from the plant (THC, CBD and CBN).
Then the results of those extracts were cross-referenced with extractions of the same sample using three different, more traditional methods: Ultrasound-assisted extraction, gaschromatography-mass spectrometry and ion mobility spectrometry (IMS).
And consistent with results from non-marijuana-related studies, the extraction method seemed to work—in under one minute.
“It has been evidenced that the developed method for the major cannabinoids extraction is a really encouraging example of the wide range of possibilities that a conventional and low cost hard cap espresso assisted extraction could offer in analytical laboratories,” according to the study.
“The quantitative extraction of THC, CBD and CBN from buds, leaves and stems has been achieved in a single and fast extraction of 40 seconds.”
The researchers noted that after using a rigorous multi-step cleaning method, the coffee machine has been “used in our laboratory during the last two and a half years without observing any damage or incident.”

Scientists Discover You Can Use Espresso Machines To Make Marijuana Extracts
Just a week after Mexico’s Supreme Court supported a person’s right to cultivate and use cannabis, a bill was introduced by a senator from the President’s governing party that would establish a fluid system for patients to obtain cannabis-based (cannabinoid) medications.
In front of nearly a dozen families with children who suffer from illness that could potentially be treated with cannabis products, Senator Cristina Diaz Salazar, a member of the Institutional Revolutionary Party, said,
“We know that this constitutes a hope for all of you to be able to mitigate the pain and suffering of your loved ones.”

Among those in attendance was the Elizalde family, parents of the first person for whom permission has ever been granted to legally import cannabinoid medicine into Mexico. In September, a federal judge ruled that the Elizaldes should be able to import cannabinoid medication under the constitutional right to protect the health of their 8-year-old daughter, Graciela.
Graciela suffers from a severe form of epilepsy, and her parents have watched her health severely deteriorate since she was just a few months old. Physicians prescribed Graciela every pharmaceutical medication available, and they even tried brain surgery. Nothing helped improve her condition, and cannabis was their last resort. Since Graciela started taking low-THC, high-CBD cannabis oil treatments, she has been able to sleep through the night for the first time.
Although this measure does not include language regarding the cultivation or wholesale of medical marijuana, it would make it possible for cannabis to be imported. Salazar explained her reasoning for introducing this measure,
“This measure is responding to the urgent need to allow availability of medicines through importation.”
If the measure passed, Mexico’s health code would be reorganized, reducing THC from a schedule I controlled substance to a schedule III. The importation of medical marijuana would also be authorized, and a 10 percent tax would be imposed. Domestic production of cannabis would remain illegal throughout Mexico.
In order for this proposal to pass, it must be approved by members of Mexico’s Houses of Congress and the Institutional Revolutionary Party. Allied lawmakers regulate the two chambers.
The speed at which the recognition of the medicinal value of cannabis has spread throughout the Mexican government is astounding. Cannabis has been illegal in Mexico since 1925, following the International Opium Convention, and polls report that public opinion of the plant is overwhelmingly negative. The negative views are largely influenced by the same type of propaganda experienced throughout the United States, and similarly to the movement in the United States, the rapid movement towards acceptance in Mexico demonstrates how quickly cannabis treatment success stories can destroy years of propaganda.
