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
There’s one word to describe the experience of first using the Puffco Pro portable vaporizer: Flavor.
While many other labels come to mind, such as stealthy, sleek, and durable, those dropping even a mediocre-quality concentrate into this popular mobile vaporizer will be impressed by the integrity of the terpene profile flavor it produces.
The Puffco Pro is rugged, but will rarely be described as such, simply because it is such a svelte gunmetal ballerina. Its all-ceramic concentrate chamber features a titanium heating coil and achieves vaping temperature nearly instantly. With some top-shelf concentrates offering up to 90 percent THC, mobile vaping is an excellent and practical way for patients to gain on-the-go relief from pain, nausea, and inflammation.
Metal + Ceramic + Titanium
Forget the specs. What does it feel like to use the Puffco Pro?
Simply wonderful. The fact that this Applesque unit is fully void of any plastic or glue goes beyond its stellar performance and great in-hand feel. For example, to ease cleaning, the atomizer can be placed upside-down in an oven at about 150 degrees Fahrenheit; residual concentrate will drip out of the unit, almost perfectly cleaning it. That would not work with a cheap plastic vape pen — many of which are considerably more expensive than the Puffco Pro.
Battery life is stellar. If dead, it requires about three hours to fully charge via USB. Once charged, it will provide multiple days of concentrate vaping. The unit’s metal even features a protective UV coating, giving it a unique feel and ultra-durable enclosure. Sadly, I accidentally kicked my Puffco across a busy street after it fell from my pocket. Only slightly scuffed, it remained fully functional.
Most vape pens offer only a single temperature, one that is relatively high and may produce harsh tokes. Models like the Puffco Pro, which allow users to dial in the temp they prefer, can produce much smoother hits via the lowest setting. To change the temperature of this model, simply click the button four times; it will cycle through low (green), medium (blue), and high (red). To prevent unintentional vaping of a pre-packed chamber, this pen can be toggled on and off via five clicks.
At $79, the Puffco Pro is an excellent value and certain to catch the attention of a wide range of concentrate and vape fans — even those on a tight budget. It features minimal draw resistance, the biggest chamber in the business (it can accommodate nearly half a gram of wax, shatter, or one’s favorite concentrate), and simply feels great in the hand.

Many are familiar with the major cannabinoids found in cannabis, such as THC and CBD, which have such great efficacy for conditions like depression, PTSD, and epilepsy. But cannabinoids are only part of the picture. Terpenes are like molecular cousins to cannabinoids and serve the primary role of delivering a wide variety of alluring aromas to cannabis flowers, but also offer a wide range of medicinal benefits as well.
In addition to aroma, terpenes deliver sometimes great medicinal value. They have been found to fight cancer and act as an analgesic (pain killer). Like amino acids, terpenes are powerful building blocks within the plant’s physiology that aid in the production of vitamins, hormones, pigments, resins, and — yes, that most prized part of the herb — cannabinoids. Cannabis plants release more terpenes when temperatures are higher (one reason they emit strong odors during the peak of harvest season).
More than 200 terpenes are available in the cannabis plant, while more than 20,000 exist in nature. They are produced in the small resin glands that appear primarily on the surface of the flowers and sugar leaves of cannabis plants called trichomes. It is estimated that there are nearly 1000 strains of cannabis that have been bred. Each of these features a distinct and unique mix of terpenes, something called a terpene profile.
Cannabis and cannabis products — such as concentrates — sold in legal and regulated states often feature a label providing a laboratory analysis that lists the exact percentages of cannabinoids and terpenes. Often, lab techs, budtenders, and pot nerds will discuss particular strains or extracts of cannabis in terms of their terpene profiles and how the overall efficacy of one profile (an individual of a particular strain) compares with other samples or methods of extracting concentrates.
Major terpenes include myrcene, pinene, and limonene. Myrcene, which conveys earthy and clove-like odors, determines whether a particular strain is indica or sativa by its percentage within the plant (further illustrating the important role played by terpenes). Pinene, a terpene also found in evergreens, has been found to increase mental focus and energy and acts as a bronchodilator — making it helpful for asthma sufferers. Limonene, as its name implies, provides an aroma of citrus and is found not only in cannabis, but also oranges, grapefruits, lemons, and limes. It has been revealed to alleviate depression and aid in digestion.
Terpenes are very volatile, delicate molecules that are easily destroyed by heat and oxidation. Popular cannabis concentrates, like BHO and CO2 oil, are mostly void of terpenes. One new extraction method called live resin preserves the terpene profile of cannabis plants. This process involves cryogenically freezing plants immediately after harvest and then using a laboratory extraction process (backyard brewers need not apply) to remove and isolate a more accurate representation of a particular plant’s mix of cannabinoids and terpenes.
What is Linalool?
Linalool, one of the minor terpenes found in cannabis, conveys a floral aroma, sometimes with a hint of spice. More than 200 species of plants produce linalool, including a variety of mints and herbs. More important, linalool serves many roles in relieving a number of symptoms, including pain, depression, seizures, inflammation (similar to limonene), and even insomnia (because it acts as a sedative). Its tranquilizing effects are helpful for those suffering with many types of psychosis.
- Analgesic: Linalool is helpful for conditions like multiple sclerosis, dystonia, arthritis, post-operative pain, and chronic pain from any source because it is a pain killer. Combined with cannabinoids of the same efficacy, linalool can be a reinforcing agent in a patient’s struggle to manage pain, especially if they are trying to avoid or reduce use of opiates such as Vicodin, Percocet, and Oxycontin.
- Antidepressant: More than 20 million people in the United States alone suffer from sometimes debilitating depression. This common psychological ailment can negatively affect one’s career, personal relationships, and even physical health. Linalool, when combined with cannabinoids like THC that are also effective in helping alleviate depression, helps form an overall strategy for using cannabis to treat these types of disorders.
- Anti-Convulsant: Just as chemotherapy is used to treat conditions other than cancer, seizures afflict those with conditions other than epilepsy, such as traumatic brain injury, brain tumors, and hydrocephalus. Most seizures feature a duration of between 30 seconds and two minutes. Typically, they do not cause lasting harm, although they seizures often very taxing, painful, or exhausting for sufferers. Seizures that last longer than five minutes are considered life threatening.
- Anti-Inflammatory: Those suffering from inflammation-based diseases, such as Crohn’s, arthritis, Alzheimer’s, asthma, fibromyalgia, dermatitis, IBS, lupus, and Parkinson’s, among many others, gain benefit from the anti-inflammatory properties of linalool (as well as a variety of anti-inflammatory cannabinoids).
- Sedative and Sleep Aid: It is estimated that 10-30 percent of people suffer from insomnia at some point in their lives, with 10 percent reported to experience chronic and severe sleep deprivation. Cannabinoids like CBN, when combined with terpenes such as linalool, help patients get the sleep they require to maintain homeostasis (balance) and health. Adequate sleep is critical for patients to most effectively fight their condition or disease.
Ancient cultures have used terpenes like linalool, available in a variety of aromatic herbs like cannabis, for millennia to treat a wide variety of conditions. 21st century research has confirmed the beliefs of these ancient civilizations, revealing strong medical efficacy for a variety of conditions.
A 2002 study published in the Journal of Phytomedicine revealed that linalool is a major anti-inflammatory agent, potentially helping with a variety of inflammation-related ailments, such as cancer, arthritis, and Crohn’s disease. The same research team, in a 2003 study, found linalool to also be a pain killer. These researchers again, in 2006, conducted another linalool study that further collected and examined data from animal models. This study reinforced the fact that linalool is a powerful anti-inflammatory.
2008 research published in the American Association of Nurse Anesthetists Journal supported the sedative qualities of linalool. The study estimated that 19 million Americans suffer from anxiety-related ailments, with 16 percent of people between the ages of 18 and 54 being patients of one or more anxiety conditions, which sometimes lead to substance abuse and mood disorders.
This study revealed linalool to be a powerful sedative that delivers real efficacy to those who suffer anxiety disorders and one of their most common side effects, insomnia. Concluded the study:
“Our data…suggested that linalool modulates the central nervous system by producing unconsciousness and degradation of motor movements.”
A 2010 study involving mice that employed three different sub-types of linalool found it to be an effective anticonvulsant, meaning it shows significant promise for those who suffer seizures, such as patients of epilepsy and brain tumors. Reported the study:
“Linalool…[was] effective in preventing tonic convulsions induced by transcorneal electroshock in the animals.”
More Research Needed
As with all areas of cannabis science, terpenes like linalool are in desperate need of well funded, robust research in the form of human trials. Until cannabis is dropped from Schedule I and real studies are permitted by reputable research institutions and laboratories, medical professionals and patients must play a guessing game in terms of the types and dosages of terpenes like linalool that are most appropriate for particular conditions.
