If you don't want to read the fairly graphic article, here's her results:
If there is any smidgen of effect, it's notional, and probably only psychological. Overall, vodka-in-a-tampon seems a very inefficient, not to mention unpleasant, way to get drunk. I suppose the positive is that there is no danger of a second round.
Makes you wonder how many of these other "disturbing teen trends" are totally untrue too.
urban legends like this have been going around forever, especially among kids, but in this age, they spread WAY faster. still i find it highly amusing that people never bother to stop and think logically about it for a minute (as the article's author pointed out, when she brought up the fact that even trying to attempt this is difficult...and painful).
while i find most of these legends pretty hilarious, i do find it a little disturbing that so many media outlets pick up on this stuff and repeat it as fact, when the reality is that it rarely is (and thus, they obviously didn't do their due diligence in corroborating the story). talk show hosts like Oprah have always been notorious for spreading this around, often taking whole hour-long episodes to scare the crap out of parents with that whole "what you'll hear over the next hour will shock you! parents, do you really know what your kids are up to?" BS at the beginning of said episodes.
remember that whole "Rainbow Party" story going around a couple years ago? Oprah spread that story like wildfire...except she left out the part that those parties NEVER ACTUALLY HAPPENED. or my personal favorite, the whole "Satanic Panic" thing in the 80's, what with the "evil" heavy metal bands and so-called "Satanic ritual killings". Geraldo was pretty fond of that one and it went on for quite a while as far as these stories go...except even the FBI finally admitted that they couldn't pin ONE SINGLE CRIME on the supposed "Satanic epidemic". ah, good times.
it still blows my mind that even well-known and famous "journalists" can't be bothered to spend the 60 seconds it takes to log onto a website like Snopes and see whether an urban legend has any truth to it.
