CBD pollen: sifted trichomes, not actual pollen

The word is misleading on two counts. This powder has nothing to do with bee pollen or any other hive product. Nor is it the true pollen of hemp, which male plants release to fertilise female flowers. Flower growers keep that pollen away, because a fertilised flower sets seed.

What the trade sells as pollen is a fine powder, blond to light brown, that resembles pollen. It consists of trichomes, the small mushroom-shaped glands covering female flowers. According to a study published in 2020 in Scientific Reports, cannabinoids and terpenes are made and stored in these glands, and they are especially dense on seedless female flowers. Their different shapes are described in our article on trichomes.

Moroccans call this powder kif, English speakers kief or dry sift. In the Phytogrammes lexicon it is filed under dry sift.

There are three steps. First the flower is dried and chilled, since cold makes trichomes brittle. Then it is rubbed gently over a screen, and the trichome heads snap off and drop through the mesh. Stacked screens grade the powder by size.

Which mesh is useful depends on head size. In a study published in 2023 in the Journal of Cannabis Research, a Canadian team measured the trichomes of two varieties under a microscope. Capitate-stalked trichomes carry most of the resin. Their heads measure 40 to 110 microns across, averaging 75 or 90 microns depending on the variety. Most of them pass through a 160-micron screen, and a 45-micron screen stops almost all of them.

Rubbing harder pushes more leaf fragments through with the resin, so a very green pollen contains more plant matter than a blond one. Static sift adds a sorting step that uses static electricity to remove them. These methods are compared in our guide to hash names, from frozen to 120u.

A three-part grinder works on the same principle. The ground flower rests on a fine screen, and the loosened trichomes fall through into the bottom chamber, where the powder builds up.

Pollen and hash have the same contents and differ only in handling. Pollen is sold loose or barely packed and crumbles between the fingers. Hash is that same sift pressed into a compact slab, by hand or with a press, sometimes with heat. Pressing alters the texture and how much surface is exposed to air, and leaves the composition as it was.

Hash can also be made with ice water, a method unrelated to dry sieving. Our guides to homemade CBD hash and to drying hashish and extracts cover these steps.

A sift concentrates the trichomes, so a gram of it holds far more cannabinoids than a gram of the flower it came from. Colour gives no clue to the figure, which has to be read on the batch analysis.

Drysift 90u, from our catalogue, is a dry sift collected on a 90-micron mesh and pressed by hand. Its batch PG-26-DBD7 shows 15.11% CBD, 1.04% CBG, 0.28% CBN and 0.16% Δ⁹-THC. The product name says 20%; the batch's reference profile is the figure that counts, and no laboratory certificate is published for this batch. On 23 September 2026 the price shown was €7.95 per gram at the 2 g tier and €1.90 per gram at the 100 g tier. The other references are in the resins, hash and pollen category.

To judge a pollen, three lines of a lab report are enough:

• the dominant cannabinoid as a percentage of mass, CBD or, for some sifts, CBG;
• Δ⁹-THC, which must be 0.30% at most;
• CBN, which forms as THC oxidises; a high value points to an old or poorly stored product.

Each line is explained in our guide to reading a certificate of analysis, and the laboratory page describes the measurement methods.

Pollen probably keeps less well than a whole flower, and the reason is mechanical. A 1976 study published in the Journal of Pharmacy and Pharmacology stored flowers, resins and cannabinoid solutions for up to two years. The main cause of loss was light, even without direct sunshine. Temperatures up to 20 °C had no notable effect. Air oxidation did cause clear losses, though smaller ones when the glands stayed intact, which the authors compare to well-filled, well-closed containers.

Pollen consists of exactly such glands, detached and sometimes broken, with a large surface exposed to air. Four rules follow:

1. an opaque glass jar, or a jar kept in a closed cupboard;
2. a full container, so that little air sits above the powder;
3. a steady temperature, away from any heat source;
4. quick opening, and closing again straight away.

Stored this way, well-prepared resins and flowers stay "reasonably stable" for one to two years, according to the authors. Terpenes are more volatile and go sooner, so a pollen that barely smells has lost most of its aroma. The labelling rules are in our article on best-before dates for hash and flowers.

Pollen is used like other resins, heated so that its cannabinoids turn into vapour. In a joint it burns and gives off the same by-products as any burnt plant matter, carbon monoxide and tar. In France it is often mixed with tobacco as well, which adds nicotine. Our article on the differences between tobacco and cannabis compares the two kinds of smoke.

A vaporiser heats without burning; the temperatures are set out in our guide to vaporising CBD. Whatever the method, CBD is not a medicine, and Epidyolex is the only authorised cannabidiol medicine.

CBD pollen follows the rules for hemp resins. The decree of 30 December 2021 authorises Cannabis sativa L. varieties listed in the official catalogues whose Δ⁹-THC content does not exceed 0.30%. It caps extracts and the products containing them at the same threshold. The Conseil d'État annulled on 29 December 2022 the decree's ban on selling raw flowers and leaves. Our article on whether CBD hash is legal covers this framework.

Food use is a separate matter. On 20 May 2026 the Ministry of Agriculture recalled that foods containing CBD, food supplements included, are not authorised and must be withdrawn from the market. Pollen is therefore sold as a non-food product. Mixed into a dish or drink for sale, it would fall outside this framework.
