Drugs have somewhat different effects, depending on how they are taken into the body. For example, injecting a given dose of opiate will make it take effect more suddenly than swallowing the same dose. Smoking cannabis feels different than eating it.
When a person swallows alcohol or some other drug, it takes time for the stuff to be digested and absorbed into the bloodstream. (More time, if the stomach is full, or the drug is dilute. That's why some people feel they don't get as intensely drunk drinking beer after dinner as drinking vodka on an empty stomach. The same total amount of alcohol feels different when it hits the bloodstream faster.) There is also an automatic defense against toxins built into the human digestive system--it's not perfect, but it helps sometimes. Some people who swallow a toxic dose of alcohol throw up before it can poison them.
An enema containing coffee or alcohol with get the active ingredient into the person's bloodstream very, very, fast. This is hideously dangerous, because the person can't vomit it up. (He or she won't even start feeling sick and stop drinking, as most people will if they try to swallow a quart of anything in a few minutes.) But a vodka-soaked tampon? A super-plus tampon is supposed to hold 15mL of fluid. That's ONE-THIRD the quantity in a shot glass.
