FAQ

The CBD used in our e-liquids is obtained through a CO2 extraction procedure. This method preserves the phytochemical components of the plant (CBD, CBG, terpenes, etc.). What’s more, it is natural and environmentally friendly. The carbon dioxide used does not harm the plant substances collected, which retain their natural flavour and aroma.

CBD extraction using CO2

This procedure is neutral for nature, as CO2 is already present in the air around us. It captures all the plant’s aromas and molecules. To extract lipophilic substances from a plant, it must be subjected to a temperature just over 30°C and a pressure of 74+ bars. The CO2 is pumped into the extractor containing the hemp flowers. The terpenes and cannabinoids are dissolved and absorbed by the CO2, which continues on its way until it arrives at a separator.

The pressure of just over 74 bars is reduced and allows the CO2 to go back to its gaseous state. The particles extracted from the hemp are then diffused in a collector. These particles form a wax.

The CO2 can be used again for extractions from other plants.

The advantages of CO2 extraction

This extraction method, essentially based on the use of CO2, is kinder to the environment than solvent extraction. What’s more, it can isolate the CBD from all the other elements of the plant.

This is the procedure used to extract CBD in the form of 99% pure crystals. It is also the method we use to make our e-liquids. Although it is the more expensive option, we have chosen this process as it is the best way to preserve the purity and natural properties of hemp. In turn, this enables us to make superior-quality e-liquids.

The quality of the raw materials has a huge impact on the quality of a CBD e-liquid. We have implemented a rigorous hemp plant selection and processing procedure in order to obtain CBD that fulfils our quality criteria and is compatible with our e-liquid recipes.

Soil and hemp variety studies

The first step in producing CBD is to select the appropriate hemp seeds. As we wanted to create a product that respects the environment, we looked for European producers. After months of discussions and testing, we selected partners who had years of experience in growing hemp.

The soil where our seeds are sown is fertile and has plenty of water capacity. Its pH is between 6 and 7.5. Our production process is certified herbicide-, fungicide-, pesticide- and heavy metal–free.

The harvest process

Only the hemp flowers that meet our quality criteria are harvested. To achieve this level of quality, we use a manual harvesting process compatible with our company’s environmentally friendly culture. Each flower is separated from the plant’s stem by hand and examined.

The hemp flowers are subjected to a natural drying process and exposed to a temperature of no more than 35°C. This drying method preserves the hemp’s powerful properties. Once dry, they are taken to the laboratory, where the CO2 extraction process takes place. The extracted CBD is used to make our e-liquids in its raw form: crystals.

CBD e-liquids have the same components as any other e-liquid: a base made from propylene glycol and vegetable glycerin, flavourings and a booster, in this case containing CBD. They can therefore be vaped with any e-cigarette. The only difference is that the wattage used must not be too high, so that the molecule is not altered.

CBD molecules and terpenes (the natural aroma at the heart of the authentic hemp flavour) used to make Marie Jeanne e-liquids are fragile and must therefore not be vaped at too high a temperature. On average, the ideal vape temperature for these liquids is 180°C. This is also the temperature at which propylene glycol evaporates, which explains why these e-liquids contain a high proportion of PG, with a PG:VG ratio of around 80:20.

To aim for this ideal temperature of 180°C, it is best to vape at no more than 15 W for optimal performance. You therefore need equipment suitable for mouth-to-lung vaping that is compatible with coils of a resistance of around 1 ohm.
