Smoking hemp: what the law says and the risks

The French legal framework regulates the production, sale and possession of hemp flowers and leaves through their THC content, currently capped at 0.30% in the finished product. It does not specifically regulate the method of consumption chosen by the buyer. That is why many shops state on their labels that the product is "not intended for combustion", a form of commercial caution rather than an explicit legal obligation, designed to present the product as a collector's item, a home fragrance or a base for infusion rather than as something smokable.

Since the order of 30 December 2021, the legality of a hemp product in France rests on two criteria: the variety grown must appear on the list of authorised varieties, and the THC content of the finished product must not exceed 0.30%. Neither of these two criteria concerns the method of consumption. Smoking a CBD flower that complies with these thresholds is not, in itself, an offence relating to THC content. That does not, however, make the practice advisable from a health point of view.

Burning plant matter — tobacco, hemp or any other plant — produces substances that irritate the airways and compounds recognised as harmful by the French health authorities, regardless of whether THC or nicotine is present. The Observatoire français des drogues et des tendances addictives (OFDT) regularly points out that the respiratory risk associated with smoking comes largely from the smoke itself, a mechanism that applies in the same way to any plant that is smoked. Combining hemp with tobacco, a common practice among some consumers, also adds the risks specific to nicotine and tobacco additives.

Vaporisation heats the flower to a temperature high enough to release cannabinoids and terpenes without burning them, which sharply reduces the production of tars and combustion substances, while retaining an inhaled form of use. Infusion — flowers steeped in a hot fat and then filtered — allows oral consumption with neither combustion nor inhalation. Our article on full-spectrum hemp extract sets out the other formats available, oils, gummies or cosmetics, which avoid the question of combustion entirely.

The legality of the sale is not the same as a recommendation to use the product by combustion. The choice of consumption method remains personal, but it deserves to be made in full knowledge of the respiratory risks associated with any inhaled smoke, whatever the plant it comes from.

CBD is not a medicine. Not advised for pregnant or breastfeeding women or for minors. Driving after consumption should be avoided.

Is it legal to smoke a CBD flower in France?

Selling flowers that comply with the 0.30% THC threshold has been legal since 2022. The regulations do not specifically address the method of consumption chosen by the buyer.

Why do some shops state that their flowers are not intended to be smoked?

It is a form of commercial caution, presenting the product as a collector's item or a home fragrance rather than as something smokable, without being an explicit legal obligation.

Is vaporisation really less risky than combustion?

It reduces the production of tars and combustion-related substances, by heating the material without burning it. That does not remove every risk associated with inhalation, but it changes its nature.

Can you mix hemp and tobacco?

It is a common practice, but it adds the risks specific to nicotine and tobacco additives to those of combustion itself.
