Spiked Drinks and Stolen Plans: Chinese Worker Jailed in Bizarre “Truth Serum” Scheme
A Chinese employee has been sentenced to three years in prison after repeatedly drugging a colleague with a sedative-laced “truth serum” in an attempt to extract confidential work plans. The shocking case, reported by the South China Morning Post (SCMP), reveals a disturbing breach of trust and workplace ethics.
What Happened?
The Bizarre Plot
The convicted man, surnamed Li, learned about a supposed “truth serum” during a business trip. The seller claimed that “just a few drops” would make someone reveal secrets. Intrigued, Li decided to test it on his colleague, Wang, by spiking his drinks during work dinners.
Three Poisonings Over Six Months
- First Incident (August 29, 2022): Li mixed the drug into Wang’s yellow wine at a dinner in Shanghai’s Xuhui District.
- Second and Third Attempts: Li later drugged Wang’s beer on two more occasions.
- Symptoms: Wang experienced dizziness, vomiting, and unconsciousness each time, but initially dismissed it as food poisoning.
After the third incident, Wang grew suspicious, realizing his symptoms only appeared after meals with Li.
What Was in the “Truth Serum”?
Forensic tests revealed the presence of two powerful sedatives in Wang’s system:
- Clonazepam – A Class II psychotropic drug (regulated in China) used to treat anxiety and seizures.
- Xylazine – A veterinary sedative sometimes illicitly used as a drug adulterant.
Both substances are central nervous system depressants, which can cause severe drowsiness, confusion, and even respiratory failure in high doses.
Legal Consequences
- Sentence: 3 years in prison + 10,000 yuan ($1,400) fine
- Charges: Endangering public safety and violating workplace ethics.
- Li’s Admission: He confessed to all three poisonings during interrogation.
Wang’s current health status remains unknown.
Why Did Li Do It?
While the exact motive isn’t fully detailed, key possibilities include:
- Corporate Espionage? Li may have sought confidential business plans.
- Personal Grudge? Workplace tensions could have played a role.
- Naïve Experimentation? Li might have genuinely believed in the “truth serum” myth.
The Myth of Truth Serums
Despite Hollywood depictions, no drug reliably forces people to tell the truth. Real-world “truth serums” (like sodium pentothal) only lower inhibitions, making users more suggestible, not necessarily truthful.
Historical Cases:
- Cold War Era: Intelligence agencies experimented with drugs for interrogations.
- Criminal Cases: Some criminals have tried (and failed) to use sedatives to extract secrets.
Workplace Safety Implications
This case highlights alarming risks in professional settings:
- Drugging as Corporate Sabotage: Could this inspire copycats?
- Lack of Awareness: Many don’t realize how easily drinks can be spiked.
- Legal Gaps: Should China impose stricter penalties for workplace poisonings?
