A hospital in the Grand Hôpital de l’Est Francilien is offering free, anonymous consultations for young people who use "pète ton crâne," a synthetic cannabinoid that is often consumed in liquid form through e-cigarettes. Unlike traditional cannabis, this substance is designed to mimic the effects of THC, the psychoactive component in marijuana, but it is chemically different and can be more potent. It is also known for emitting little or no odor, making it harder to detect compared to other substances. Dr. Mathieu Royer, who oversees the addiction service at the hospital, has raised concerns about the serious health risks linked to "pète ton crâne." These risks can include rapid heart rate, hallucinations, anxiety, and in severe cases, seizures or even death. The substance is particularly dangerous because it is often sold without clear labeling or dosage instructions, increasing the risk of overdose or adverse reactions. The hospital has introduced these specialized consultations in response to a reported rise in the use of "pète ton crâne" among adolescents. Local municipalities have noted an increase in cases through middle and high schools, prompting healthcare providers to take proactive measures. The anonymous nature of the consultations aims to encourage young people to seek help without fear of judgment or repercussions. This initiative highlights the growing concern among medical professionals and educators about the spread of synthetic drugs among youth. While the hospital provides a safe space for discussion and support, experts emphasize the need for broader awareness and prevention efforts to combat the rising trend of substance use among young people.
