evidence: Activated charcoal tablets are unlikely to be effective in counteracting date rape drugs; individuals who have been given date rape drugs should seek medical attention [...] Though activated charcoal is the most used method of gastrointestinal decontamination in the developed world, an activated charcoal tablet would not be useful to counteract date rape drugs in the manner described in the Facebook post. The dose of activated charcoal in tablets is too low and the formulation is not ideal. The activated charcoal tablets would need to be taken soon after the date rape drug, which can be hard because many of the drugs associated with DFSAs are odorless and tasteless, and are absorbed quickly by the body. Lastly, activated charcoal would have no effect on alcohol, which is the drug most commonly associated with DFSAs and does not adsorb to activated charcoal. [...] The use of activated charcoal to counteract date rape drugs seems to be minimal in my opinion. In theory, activated charcoal would stop some of the absorption of the most common rape drugs (although there are multiple substances) in the stomach. The problem is that most date rape drugs (like GHB) are odorless, tasteless and have a rapid onset. At the point of time, when the victim notices the first symptoms, the major part of the drug has already been absorbed, so taking activated charcoal would not have a relevant effect anymore. Furthermore, one of the symptoms of date rape drugs is reduced consciousness or coma, which are strict contraindications for taking activated charcoal because of the risk of aspiration.
