Cannabis contains more than 500 different compounds, including a unique class of terpeno-phenolic compounds known as cannabinoids. D9-tetrahydrocannabinol (THC) and cannabidiol (CBD) are the most extensively studied cannabinoids. They have been associated with the therapeutic and medicinal properties of the cannabis plant and also with its popularity as a recreational drug. In this paper, an industrial method for cannabis extraction using 915 MHz microwaves coupled with continuous flow operation is presented. The main advantages of the microwave-assisted extraction (MAE) are associated to the continuous-flow operation at atmospheric pressure which allows for higher volumes of biomass to be processed in less time than existing extraction methods, with improved extraction efficiency leading to increased final product yields, improved extract consistency and quality because the process does not require stopping and restarting material flows, and ease of scale-up to industrial scale without the use of pressurised batch vessels. Moreover, due to the flexibility of changing the operation conditions, MAE eliminates additional steps required in most extraction methods, such as biomass decarboxylation or winterisation, which typically adds at least a half day to the extraction process. Another factor that sets MAE apart is the ability to achieve high extraction efficiency, i.e., up to 95% of the active compounds from cannabis biomass can be recovered at industrial scale. Keywords: THC; CBD; 915 MHz; continuous flow 1. Introduction Cannabis is a genus of flowering plants belonging to the cannabaceae family with three main species: Cannabis sativa L., Cannabis indica L., and Cannabis ruderalis L., Figure1[1]. Cannabis has a long history of being used for medicinal, therapeutic, and recreational purposes. Cannabis is known, for example, to be capable of relieving nausea (such as that accompanying chemotherapy), pain, vomiting, spasticity in multiple sclerosis, and of increasing appetite. The importance of cannabis in therapeutics is emphasized by the ever-increasing number of research publications related to the use of cannabis and its derived products to treat various indications [2–5]. Cannabis contains more than 500 different compounds, which include terpenes, flavonoids, lipids, sterols, chlorophyll, fatty acids, salts, sugars, and a unique class of terpeno-phenolic compounds known as cannabinoids or phytocannabinoids. More than 100 cannabinoids have been identified in different cannabis plant strains. Examples include D9-tetrahydrocannabinolic acid (THCA), cannabinoldiolic acid (CBDA), cannabinolic acid (CBNA), cannabigerolic acid (CBGA), and cannabichromenic acid (CBCA) [5–7]. In fresh plant material, all cannabinoids are present in their acidic form.

    Basic Cannabis Knowledge 101 Cannabis is the genus of three species of flowering plants: Sativa and Indica and ruderalis (naturally lower in THC). Marijuana is the female cannabis plant in which flowers contain a percentage of cannabinoids and hold both medicinal and psychoactive properties. There are 488 chemical entities, and at least 66 are cannabinoid compounds. THC and CBD are not the only medicinally active compounds found in cannabis. Sativa plant grows taller, are lighter in color. The plant takes longer to flower and produces more Sativa cerebral effects. This plant is the largest of the three families. Symptom Relief: Depression, ADD, fatigue, Mood Disorder. Indica plants are shorter, bushier and produce Indica sedative physical effects. Symptom Relief: Pain, anxiety, insomnia, muscle spasms. Cannabis Ruderalis is a low-THC species of Ruderalis Cannabis. Very small plant and fast growing. What is Hemp? HEMP: Active Ingredient-CBD. No psychoactive effects.

  • Psychedelic Resource List (PRL) Was Born in 1994 As a Subscription-Based Newsletter
    A Note from the Author… The Psychedelic Resource List (PRL) was born in 1994 as a subscription-based newsletter. In 1996, everything that had previously been published, along with a bounty of new material, was updated and compiled into a book. From 1996 until 2004, several new editions of the book were produced. With each new version, a decrease in font size correlated to an increase in information. The task of revising the book grew continually larger. Two attempts to create an updated fifth edition both fizzled out. I finally accepted that keeping on top of all of the new books, businesses, and organizations, had become a more formidable challenge than I wished to take on. In any case, these days folks can find much of what they are looking for by simply using an Internet search engine. Even though much of the PRL is now extremely dated, it occurred to me that there are two reasons why making it available on the web might be of value. First, despite the fact that a good deal of the book’s content describes things that are no longer extant, certainly some of the content relates to writings that are still available and businesses or organizations that are still in operation. The opinions expressed regarding such literature and groups may remain helpful for those who are attempting to navigate the field for solid resources, or who need some guidance regarding what’s best to avoid. Second, the book acts as a snapshot of underground culture at a particular point in history. As such, it may be found to be an enjoyable glimpse of the psychedelic scene during the late 1990s and early 2000s.

A FEW THINGS TO KNOW! 01 •Hemp is a variety of Cannabis sativa referred to as Cannabis Sativa L. • Contains high levels of CBD & low levels of the psychotropic compound THC • The psychoactive properties of cannabis show up at around 5% so marijuana with lower levels of THC may not be psychoactive. • Legally all cannabis plants with below .3% THC are classified as hemp • Historically hemp has been bred for its fiber, but in more recent years has been cultivated for its flowers which produce high levels of CBD RELATED ARTICLES ONLINE https://www.leafly.com/news/cannabis-101/what-is-cbd https://www.leafly.com/news/cannabis-101/what-is-cbd-oil https://www.leafly.com/news/cbd/cbd-vs-thc WHAT IS HEMP? HOW ARE THESE PLANTS DIFFERENT? The various species of cannabis are still debated but these three species; Cannabis sativa, Cannabis indica, and Cannabis ruderalis, are the most widely accepted. The greatest differences between them are due to selective breeding for fiber, seed or high levels of certain cannabinoids (more on cannabinoids later). Their appearance and cultivation methods will vary based on the desired use of the final crop. HOW ARE THESE PLANTS DIFFERENT? CANNABIS SATIVA 01 • Indigenous to Eastern Asia • Used as a source of industrial fiber, seed, oil, food, recreation, religious practices and medicine • Requires at least 13 hours of light to stay in vegetative state CANNABIS INDICA 02 • Indigenous to Afghanistan • Mainly used for extraction and medical purposes due to high levels of THC • Requires 15-18 hours of light to stay in a vegetative state CANNABIS RUDERALIS 03 • Indigenous to central Europe, eastern Europe, and Russia • Used in Russian folk medicine and more recently for extracting its high levels of CBD • Transitions from veg to flower with time, not light cycle WHAT IS HEMP?

Past research has shown that cannabis can be indicated for symptom management disorders, including cancer, chronic pain, headaches, migraines, and psychological disorders (anxiety, depression, and post-traumatic stress disorder). Active ingredients in cannabis that modulate patients' perceptions of their conditions include Δ9‐ tetrahydrocannabinol (THC), cannabidiol (CBD), flavonoids, and terpenes. These compounds work to produce effects within the endocannabinoid system to decrease nociception and decrease symptom frequency.

  • Colorado Cannabis Faqs
    Cannabis FAQ We get many inquiries about what is happening in Colorado after the two state constitutional amendments regulating cannabis. We hope that this document will provide some basic information and where to find resources. What are the components of marijuana? Marijuana is comprised of hundreds of individual molecules known as cannabinoids and terpenes. Cannabinoids are molecules unique to cannabis that can produce a wide variety of both therapeutic and adverse effects. Approximately 66 cannabinoids have been discovered, yet due to limited research, we only know a fair amount about a select few. The most well-known cannabinoid is Delta-9 Tetrahydrocannabinol. Next in line is Cannabidiol (CBD). Terpenes are organic molecules that emit aromas. These molecules are responsible for the unique smells and flavors that cannabis brings to the table and also can produce physiological effects. Common terpenes found in cannabis include Myrcene, Linalool, and Limonene. The cannabinoid and terpene profile of any cannabis plant make up its chemotype which helps us to predict what the effects will be. adai.uw.edu/marijuana/factsheets/cannabinoids.htm (Cannabinoid Factsheet) How is marijuana used? There are many ways to use marijuana and each one affects users differently. Factors include dosage, subject’s body composition, and tolerance. Marijuana can be smoked like a cigarette (a joint) or a cigar (a blunt). Marijuana can also be smoked in a pipe; small glass (spoon) and water (bong) pipes are common. Sometimes people mix it in food and eat it or brew it as a tea (edibles). Smoking oils, concentrates, and extracts from the marijuana plant are also popular.
