There's some crazy statistics behind the passage of these "anti drink spiking" measures.
According to: https://calmatters.org/politics/2024/07/california-drink-spikinglaw-bars/
A survey published in 2016 in the American Psychological Association’s journal “Psychology of Violence” found that 8% of 6,064 students surveyed at three universities believed they’d been slipped drugs. Eighteen percent of more than 45,000 respondents in a 2022 global survey from a London-based research firm reported that they had been drugged. The same survey noted that 92% of the victims didn’t report their suspicions to police.
