    "description": "Drink spiking occupies a disproportionately large space in risk perception relative to its confirmed prevalence. Media coverage, campus safety campaigns, and social media have elevated the image of a stranger slipping a drug into an unattended drink to near-iconic status as a sexual assault mechanism. Surveys of college students find that awareness of drink spiking is near-universal and fear of being drugged is common, even among students who have never personally experienced or witnessed it. The perception is not baseless — drink spiking does occur — but the specific mechanism (covert administration of GHB, Rohypnol, or ketamine) is substantially rarer than the broader category of drug-facilitated sexual assault, where voluntary alcohol consumption by the victim is the dominant intoxicant in the vast majority of forensically confirmed cases.\n",

    "assumptions": "The best available prevalence data come from college student surveys, which are not nationally representative of all US adults. Swan et al. (2016) found 7.8% of 6,064 students at three universities reported suspected drugging. Other studies report 6-9% among college-aged women. However, college students have substantially higher social drinking exposure than the general population, and many self-reported drugging events may reflect unexpectedly strong alcohol effects rather than actual spiking — the researchers explicitly note they cannot verify actual drugging. Forensic toxicology studies of confirmed drug-facilitated sexual assault cases find classic spiking agents (GHB, Rohypnol, ketamine) in only 2-4% of samples; alcohol alone accounts for the vast majority. Estimating a lifetime figure: if the college-period risk is ~7.8% over 4 years of elevated exposure, and non-college-period risk is much lower, a rough lifetime estimate of ~6% accounts for both the peak-exposure college years and lower- exposure adult years. This is highly uncertain and likely an overestimate of actual covert drugging (vs. self-attribution of excessive intoxication). Uncertainty band: low end uses forensic confirmation rates extrapolated to general population (~2%); high end uses self-reported suspected rates (~10%).\n",

  "caveats": "This entry addresses a specific mechanism — covert administration of drugs into someone's drink — rather than the broader category of drug-facilitated sexual assault, where voluntary alcohol consumption by the victim is the dominant intoxicant. The \"overrated\" framing applies to the specific spiking mechanism, not to drug-facilitated sexual assault as a whole, which is both common and serious. Self-reported suspicion of being drugged (6-9% of college students) likely overstates actual covert spiking because the symptoms attributed to spiking — unexpected intoxication, memory gaps, loss of motor control — are also produced by drinking more alcohol than intended, combining alcohol with medications, or drinking on an empty stomach. GHB is detectable in urine for only 6-12 hours after ingestion, so some genuine spiking cases may be missed by toxicology screens conducted after that window. The college-student data are not generalizable to all US adults; social-drinking patterns differ substantially by age, and the majority of reported spiking occurs in the 18-24 age bracket. This entry should not be read as minimizing the reality of drink spiking, which is a serious crime when it occurs, but as calibrating the frequency of the specific mechanism relative to public perception.\n",
