A former French senator has been sentenced to prison after being found guilty of spiking a fellow lawmaker’s drink with ecstasy in a case that has reignited national debate around drug-facilitated sexual assault, also known as “chemical submission.”
Joel Guerriau, 68, was handed a four-year prison sentence by a Paris court, with 18 months to be served behind bars. He was also ordered to pay €5,000 (£4,348) in damages to MP Sandrine Josso for emotional distress, according to French media reports.
The verdict follows a disturbing incident that took place in November 2023 at Guerriau’s Paris flat, where Josso, now 50, had been invited to celebrate his re-election.
MP Says Celebration Turned Into a Nightmare
According to court documents quoted by French media, Josso told the court she began feeling unwell shortly after drinking a glass of champagne at Guerriau’s home.
“I had gone to visit a friend and I discovered an aggressor,” she said while giving evidence during the trial.
Josso described how she suddenly felt weak and disoriented, but tried to hide her condition out of fear.
“He looked at me insistently. I’d never seen him that way,” she testified. “I didn’t want to show him my weakness because I was worried that if I told him I wasn’t feeling well, he would have forced me to lie down.”
She eventually managed to leave the flat and, with the help of a colleague, went to hospital. Toxicology tests later revealed that her blood contained three times the recreational dose of MDMA, commonly known as ecstasy.
Guerriau Admitted Spiking Drink but Denied Intent
During the trial, Guerriau admitted that the drink Josso consumed had been spiked with MDMA. However, he maintained that it was an accident and denied any intention of sexually assaulting her.
He told the court that he had been suffering from depression and had planned to take the drug himself the night before the incident. According to his account, he did not consume it and later mistakenly served the spiked glass to Josso.
“I feel sorry for Sandrine,” Guerriau told the court. “I am disgusted with myself, with my recklessness and my stupidity.”
He added that he wanted to speak out about the dangers of such substances, claiming that the risks of drugs like ecstasy were not discussed enough.
Court Unconvinced by Defence
The court rejected Guerriau’s explanation, pointing to inconsistencies in his testimony. Prosecutors also questioned his internet searches related to ecstasy and the drug GHB, often associated with drug-facilitated sexual assault.
When asked about the searches, Guerriau said he had no recollection of them.
“I was on the train, thoughts and ideas just come to you,” he said, adding that members of government should take an interest in “all current events.”
Despite his defence, the court found him guilty, triggering strong reactions across France.
‘A Huge Relief’ for the Victim
Shortly after the verdict, Josso described the ruling as a “huge relief,” according to AFP.
Ahead of the trial, she had spoken openly about the lasting psychological impact of the incident.
“What I went through is still very painful,” she told French media. “Psychological trauma feels like being frozen in time. I jump at the slightest thing. I’ve become very vulnerable.”
Josso, who remains an MP for the centre-right MoDem party, has since become a prominent campaigner against chemical submission and drug-facilitated sexual violence.
Wider Spotlight on Chemical Submission
The case has drawn comparisons with other high-profile trials in France involving chemical submission. Josso has joined an association founded by Caroline Darian, whose mother was a victim in a notorious case where a man was convicted in 2024 of drugging his wife and inviting strangers to rape her over several years.
Darian and her brother David were present in court during the Guerriau proceedings, highlighting the growing movement demanding stronger protections for victims and harsher penalties for perpetrators.
Political Fallout
Guerriau, a centre-right politician from the Horizons party, was suspended when the allegations first emerged. He resigned from the Senate in October last year.
Following Tuesday’s verdict, his lawyers announced plans to appeal the conviction.
As public debate continues, the case has intensified calls for greater awareness, legal reform, and accountability surrounding drug-facilitated sexual assault — a crime that many victims say remains under-reported and misunderstood.
