PTC: Synthetic Cannabinoids in E-Cigarettes Pose Significant Risks

Paris – 19 July 2026: The drug known by the abbreviation PTC is once again becoming a focus of health education. The term generally does not refer to plant-based cannabis, but to a synthetic cannabinoid. These laboratory-made substances mimic certain effects of cannabis, but can be significantly stronger and far more unpredictable.

PTC is often offered as a liquid for e-cigarettes. It may also be sprayed onto dried herbal mixtures or sold as a powder. Its outwardly inconspicuous form in a vape can increase the risk: users may not reliably know which substance or concentration it contains. Composition and dosage can vary considerably from one batch to another.

Drogues Info Service points out that synthetic cannabinoids can be stronger, more dangerous and more addictive than natural cannabis. The specialist agency lists anxiety, severe agitation, irritability and hallucinations among the possible acute effects. Serious psychiatric, cardiovascular and digestive symptoms are also possible. The risks cannot be reliably assessed before use.

According to the interministerial body MILDECA, the risk of overdose is particularly high. Such poisoning can be life-threatening. The authorities also stress that the different chemical variants and their changing composition make monitoring more difficult. The name PTC therefore does not necessarily refer to a single substance, but can be used for various synthetic active ingredients.

In France, numerous substances from this group are classified as narcotics. Nevertheless, the rapid development of new molecules can create problems for health and law-enforcement authorities. Specialist information therefore advises against consuming e-liquids and other products of unknown origin and against sharing e-cigarettes with other people.

If symptoms occur after inhaling an unknown product, prompt medical assistance is important. Altered consciousness, seizures, breathing problems, severe palpitations or pronounced confusion are emergency warning signs. In such cases, relatives should call emergency services on 15 or 112 and, where possible, provide emergency responders or medical staff with information about the product used.

For young people and parents, education remains crucial, as the term PTC can appear harmless in social groups and online retail. Official advisory services recommend seeking professional help early in the event of questions about use, addiction or possible poisoning. Drogues Info Service can be contacted anonymously in France and offers telephone advice in addition to information.
