Kief / Dry Sift: Cannabis Flower THC Crystals

Medically Reviewed on Jun 28, 2021 by Dr. K Langdon

Kief (aka dry sift) refers to the resinous trichomes of cannabis that may accumulate in containers or you can sift from loose, dry cannabis flowers with a mesh screen or sieve. Also, it contains a much higher concentration of psychoactive cannabinoids, such as THC, than that of the cannabis flowers from which it is derived. Traditionally, it has been pressed into cakes of hashish for convenience in storage but can be vaporized or smoked in either form. After the kief is collected it is heated and pressurized, which turns it into hashish.

What is Kief (Dry Sift)?? 

Kief (aka dry sift) refers to the resinous crystals that cover marijuana buds. These trichomes may accumulate in containers or be sifted from loose, dry marijuana flowers with a mesh screen or sieve. Kief contains a much higher concentration of psychoactive cannabinoids, such as THC, than that of the cannabis flowers from which it is derived. Traditionally, kief has been pressed into cakes of hashish for convenience in storage but can be vaporized or smoked in either form. After the kief is collected it is heated and pressurized, which turns it into hashish. With marijuana legalization in full effect, products such as kief are becoming more common in the cannabis Canada community. 

Common Benefits of Using Kief 

The biggest advantage of using kief is that you can just add it to your weed to make it more potent. In addition, dry sift requires much less plant material to reach the desired set of effects. Make sure to save all those little crystals because each one will contribute to a higher THC dose. Also, the high-terpene count contributes to the therapeutic effects by working with cannabinoids to produce a broad range of sensations. Below are some of the most common effects associated with weed use:
Relaxation Happiness Uplifted-ness
Focus Creativity Energy 
Euphoria Lethargy Sedation
Hunger Lethargy Giggles

Different Types of Cannabis Concentrates

There has been a variety of weed concentrates to hit the Canadian market throughout the years. Below are some of the most common cannabis concentrates found in Canada. Shatter: This group of concentrate belongs to the weed wax family. Weed shatter is a wax that is a hard substance that is clear and typically amber in color.  Hash: These products are made by compressing trichomes together to make this product. Hashish (aka hash) is one of the oldest and easiest weed concentrates to make and find on the market.  Oil: Marijuana oil is one of the most common forms of weed extract in Canada. It can be taken in a variety of ways, where the most common is placing a few drops under the tongue.  Budder: This is another member of the weed wax family. Budder wax has a softer and more pliable structure and is relatively easy to work with.  Live Resin | Terp Sauce: These are high terpene products. This means that live resins and weed sauces attempt to maintain as much of the original plant flavors as possible. This makes for some of the tastiest and most flavorful concentrates on the market.  Distillate: Marijuana Distillate is one of the purest forms of weed concentrate. The majority of unwanted plant material gets removed in the distillation process.  Moon Rocks: These are basically buds that have been dipped in concentrate and then covered in kief. Moon rocks are a triple treat of ganja goodness.  Phoenix Tears: These items belong to the cannabis oil family. The difference between THC Phoenix Tears and marijuana oil is in the way it is extracted. The end result is a product that is taken in the same way as to weed oil.  Topicals: These items are different from the rest of the cannabis concentrates because topicals are meant to be applied externally. Cannabis creams are not intended to be ingested. Cannabis creams are applied to the affected areas on the skin.

Best Ways to Take Dry Sift

The best way to take kief is to add it to a joint. Think of it as a dressing that spices up your dish. Alternatively, you can add some with your weed to a bong, pipe, or vaporizer. There are plenty of uses of dry sift and it is an item that users can get creative with.
