How is cbd extracted from hemp

0

Cannabidiol (CBD), one of the three main chemicals found in the trichomes of the cannabis plant, has gained a lot of attention in recent years as more studies show a variety of potential applications for it. You can find CBD in almost every type of cannabis plant including:

  • cannabis plants containing THC, the psychoactive chemical that makes you feel ‘high’
  • varieties of the cannabis plant specifically bred to be high-CBD/ low-THC
  • industrial hemp plants that contain no THC and have no psychoactive effect

There are a number of ways of extracting CBD from any of these varieties of cannabis. If the plant you start with contains only CBD (like industrial hemp or a high-CBD cannabis strain); there are multiple extraction methods which are very simple and require little equipment.

The most common methods use some type of solvent. This can be a liquid solvent, CO2, or an oil solvent. If the plant material you start with contains THC as well as CBD (such as smokable cannabis), the process to separate CBD from other cannabinoids is more complex and generally requires professional equipment. To avoid getting too technical, let’s look mainly at extraction methods for CBD-only plants.

Liquid Solvents

In this method, plant material like flowers and trim are put into a container. Liquid solvent (usually butane, isopropyl alcohol, hexane, or ethanol) is run through the plant matter to strip it of cannabinoids and flavours and transfer them into the liquid. Then, the liquid is evaporated away from this mixture to leave only concentrated chemicals and flavours in the form of an oil.

CBD extraction
benefits of this method are many— it is the most simple, equipment-free, and inexpensive way to extract CBD, but not without some downsides. One concern is that solvents can leave traces of impurities in the finished CBD oil (meticulous processing methods and the right solvent can minimise this). Also, some liquid solvents remove chlorophyll from the plant along with cannabinoids and flavours, giving the finished oil a greener colour and more bitter taste.

However, because these negative effects can usually be countered by adjusting specifics in the process, this remains the most common method for CBD extraction.

C02 Extraction

Carbon Dioxide (C02) is a unique molecule that can function as any state of matter— solid, liquid, or gas— depending on the pressure and temperature it is kept under. Because variables like pressure and temperature have to be kept very specific in a C02 extraction, this extraction method is usually done with a piece of equipment called a ‘closed-loop extractor’.
This machine has three chambers: the first chamber holds solid, pressurised C02 (commonly known as ‘dry ice’), the second chamber contains dry plant material and the third chamber separates the finished product.

When performing the extraction, the solid C02 from the first chamber is pumped into the second with the plant material. This second chamber is kept at a specific pressure and temperature which causes the C02 to behave more like a liquid (although it’s actually somewhere between a liquid and gas in this state, referred to as supercritical C02) so that it runs through the plant material and extracts chemicals and flavours, much like in the liquid solvent process. Then, the C02-cannabinoid mixture is pumped into a third chamber where it is kept at an even lower pressure and higher temperature so that the C02 gas rises to the top of the chamber while the oils containing chemicals and flavours from the plant material fall to the bottom to be collected for consumption.
CBD Extraction C02

There are many benefits of this method. It doesn’t require a long evaporation process like a liquid solvent extraction and there is minimal risk of contaminants in the finished product.
Because this method carefully controls temperature and pressure, it can also be used to separate CBD from cannabis also containing THC.

CBD extracts from the plant at a lower temperature and pressure than THC, so careful adjustment of the pressure and temperature in the second chamber can isolate the specific cannabinoid you want to extract. Closed-loop extractor systems are very pricey, however, which is why this type of extraction is generally only used by professional CBD producers.

Oil Extraction

Using oils, especially olive oil, to extract cannabinoids from hemp and cannabis is a practice that dates back to biblical times or even earlier.

Many home-producers who make their own CBD products still employ this simple extraction method. First, raw plant material must be decarboxylated, or heated to a specific temperature for a certain length of time to activate the chemicals in the plant. Plant material is then added to olive oil and heated to 100°C for 1-2 hours to extract the cannabinoids. With this method, the olive oil cannot be evaporated away after the process, so users must consume much higher quantities of this type of extracted oil than the highly-concentrated oil produced by other methods. Infused olive oil is also highly perishable, and so must be stored in cold, dark place.

This makes it unviable for commercial CBD producers, but a simple, safe, and inexpensive option for individual enthusiasts.

Hemp tea why you should drink it

Marijuana herbal tea and green cannabis leaves

The Hemp plant is an incredibly versatile and healing herb, the entire plant can be eaten, cooked, brewed, or extracted – from roots to flower, leaf, and seed. We have already written about the CBD oil, hemp seeds, and juiced cannabis, now, lets have a look at hemp tea.

Let’s take a look at hemp tea

Tea is an ancient drink originating from Asia.  Traditionally it is prepared with tea leaves, however, steeped hemp leaves can do the job just as well.

Hemp tea has a greenish color which is caused by plants growing mature longer and by harvesting at the time when the CBD content is at its highest level.

Don’t worry about THC (the cannabis compound getting you high) because hemp contains no more than 0.2 %. At this small concentration, you will not feel any kind of  “high” after consuming the tea.hemp tea

Is there CBD in Hemp tea?

Hemp teas made from the finest flowers and trim from hemp plants are rich in antioxidants and cannabidiol (CBD).

CBD or cannabidiol is one of the most prevalent cannabinoids found in the trichomes of the female cannabis plant and hemp. It is non-psychoactive, non-toxic and doesn’t have side effects. Because CBD is no water soluble, it’s recommended to drink hemp tea with a dash of fat as milk. Coconut oil or a small piece of regular butter will work too.

CBD vs thc whats the difference?

The cannabis plant secretes hundreds of chemical compounds, among which cannabinoids. 140+ cannabinoids have been discovered so far, and two of them are produced in greater quantity. You guessed it: THC and CBD.

They’re both cannabinoids

The cannabis plant secrets hundreds of chemical compounds, among which cannabinoids. 85 cannabinoids have been discovered so far, and two of them are produced in greater quantity. You guessed it: THC and CBD.

With different effects:

THC is credited with causing the « high » in cannabis consumption. Its psychoactive effects have known recreational and spiritual applications since 2,700 B.C., only to be isolated in 1954 by scientist Raphaël Mechoulam.

More discreet was CBD: it does not make you “high”. Its use and applications can be traced back to centuries. Mechoulam (yes, him again) actually discovered it a year before THC! The first “CBD study” came in 1980, and it was only in 1998 that the case was made for the use of CBD-rich cannabis varieties.

And a different legal status:

Because of its psychoactive effects, THC has been listed as a substance by the 1971 Convention on Psychotropic Substances, making it illegal in most countries.

However, CBD was never considered a psychotropic substance and was therefore never listed as a controlled substance. The only countries where it is officially controlled is Israël and Canada.

High THC cannabis plants are called Sativa and are illegal

Remember:

  • THC and CBD are both natural compounds of the cannabis plant, known as cannabinoids.
  • High THC cannabis plants are called Sativa while high CBD strains are called Indica
  • THC is a controlled substance because of its psychoactive effects.
  • CBD has no psychotropic effects. It is legal almost everywhere, and it is being studied and used by millions of people around the world.
  • cannabis-powered product that contains CBD, but no THC, is legal in most of the world.

Cannabis learn to spot good pot

0

If you plan to buy a car, you research your car, read reviews and get informed before you buy. It is part of being a smart consumer. Buying weed is no different. In order to enhance our smoking and/or vaping experience, one must learn to spot the signs of good vs bad cannabis.

Today everybody claims to have high-quality cannabis in stock, but how can you tell who is genuine and who is trying to make a quick buck?

Look

  • Look for crystals. These crystals, known as trichomes, contain terpenes, CBD and THC. If you can look at your weed closely and see lots of crystals in it, it’s a safe bet that the bud will be high in cannabinoids.
  • Look for hairs. These hairs or pistils are an indicator of plant maturation. The pistils change from white to yellow, orange, red and brown. However, they add little to taste or potency
  • No seeds, no stems! This is one of the golden rules of bud buying. They add next to nothing to the experience, stems can annoyingly pierce your papers, and seeds will “pop” when under high heat.
  • It should be green. This sounds obvious but buying brown weed is like buying brown lettuce, you just wouldn’t do it! Purple bud, on the other hand, is very desirable and is indicative of selective breeding for anthocyanins pigments, which give it the purple colour.

The Smell

If you are looking at acquiring marijuana, do more than just sniff an open bag.
GET IN THERE, break up a bud, and smell the inside of it.

The potency of the smell is a key to figuring out quality. Terpenes are what you smell, and knowing what they are will deepen your appreciation of cannabis and you will be able to recognise nice diesel, earthy or fruity smells.
Sometimes it will be so strong that you can smell it through the bag. Next time you have some weed, take some time to smell it and figure out what exactly good weed smells like.

The Taste

Whether it’s a vaporiser, bong, waterfall, pipe, etc, this category of critiquing marijuana is self-explanatory. Everyone’s tastes are different but potency and flavour profiles provide a diverse range of effects and individual experiences that amplify the consumer’s connection to the cannabis plant.

First-class cannabis will have a thick coat of sugary resin that contains the cannabinoids and terpenes, giving the plant its powerful effects and captivating flavours. Secreted in the same glands that produce cannabinoids, terpenes are the pungent oils that colour cannabis varieties with distinctive flavours like citrus, berry, mint, and pine

good vs bad

The Touch

It shouldn’t be too dry. Good weed is not going to be dry or feel like it’s been sitting out in the sun for too long. If there is no stickiness, this is not a good sign. Keep your weed from getting dry with glass jars.

There is a reason why rappers always brag about having that “sticky icky.” Stickier weed that is harder to break up contains more resin and will always get you “higher” than weed that just crumbles as you break it up.

CBD vs Nicotine

0

Nicotine and CBD are both compounds produced by plants. Nicotine is extracted from tobacco and CBD from Hemp. Hemp is a legal strain of cannabis that does not get people high, that’s why it’s grown by thousands of farmers in Europe and USA.

This article reviews the main differences between CBD and Nicotine and explains why CBD e-liquids should replace “regular e-liquids” in the coming years.

What is Nicotine?

“A toxic colourless or yellowish oily liquid which is the chief active constituent of tobacco. It acts as a stimulant in small doses.”

Nicotine stimulates the release of dopamine, also known as “Bliss Molecule”, a powerful neurotransmitter playing in the pleasure circuits of the brain. A brain addicted to nicotine constantly craves nicotine so that more dopamine will be released and give it those intense pleasurable sensations again.

Cigarette smoke contains more than 4,000 compounds, many of which are toxic and damage our cells. Included in these compounds are acetone, used in nail polish remover; arsenic, often found in insecticides; benzene, a cancer-causing agent; ammonia, used in dry cleaning; and cadmium, which causes cancer of the liver and kidney and brain damage.

Nicotine is addictive but did you know that:

  • It’s five to 10 times more potent than cocaine or morphine in producing behavioural and psychological effects associated with addiction, according to a report produced by the UK’s Royal College of Physicians in 2007.
  • It can contribute to sleep disorders. It stimulates the nervous system and when taken at nighttime it ensures that the user is alert and awake rather than in deep sleep
  • It binds to an area of the brain known as the adrenal medulla, which increases the flow of adrenaline. This in turn causes increased blood pressure, heart rate and respiration, and these conditions exacerbate existing heart and blood pressure problems.

Electronic cigarettes with nicotine e-liquids have been a popular way to consume it without the toxicity from the smoke. But lately, more and more vapers have been switching from Nicotine to CBD e-liquids.

What is CBD?

Cannabidiol (CBD) is one of the most prevalent cannabinoids found in cannabis. CBD is non-toxic and doesn’t have any relevant side effects. Don’t expect to get “high” off of this compound. CBD is not psychotropic and has a very wide range of applications in e-liquids, food, cosmetics…

Because of its non-toxicity and non-psychotropic nature, CBD is becoming the best choice for smokers looking to get into vaporization, and more and more vapers are switching from Nicotine to CBD.

CBD CULTIVATION

Data taken from Google Trends shows how interest in Cannabidiol has taken over in the last year. And the trend is just starting.
