15 mg's is hardly enough to overdose. At most it may cause some nausea/stomach discomfort. Why not just take them as prescribed? Whats wrong with one? If your friends friends friend really insists on taking two or more and is that concerned he could play it safe and just take one, wait about an hour or more, see how he feels, and if he feels okay then take another.
Now assuming that the anal use tag is there for a reason and not just to be cute. Hydrocodone
has a rather high bioavailability when taken orally especially in comparison to other Opiods/ates so SWIM
doesn't think plugging
would produce much stronger effects. However some people plug pills such as these due to the Acetaminophen
content. Supposedly it is less damaging to the liver when plugged. This is something SWIM is unsure of.
If one were to plug Hydrocodone or any pill for that matter the best way is by crushing the pill up into powder, mixing it with water and then using an oral syringe to inject the fluid into their ass.
SWIM believes there is a slight increase in bioavailability for Hydrocodone - He knows there is a tremendous increase for other opiates
such as Morphine
or any Morphine derivitaive so when using any drug
anally it is smart to start off with approx. half of ones usual dosage.
