Plugging (or anything for that matter) cant really be compared to IV. But lets just try... When plugged, there is some sort of a SMALL SUBTLE rush, that comes on very slow (vs. IV'd). Whatever dose you take orally, take that plugged, or possibly a little less your first plug. Lets say your plugging opiates. there is a slight rush (almost unnoticable unless your laying down relaxed), the onset is much faster than orally dosing, the high will outlast an oral dose, and also the high from plugging feels like its more intense, and i guess you could say 'cleaner'.
The capillaries in your anus is what absorbs the 'oxycodone' (or what have you).. And there are ALOT of capillaries in there. When you say you dont know what to take orally, we have no idea what substance you are referring to.. So lets say your taking oxycodone, if you are use to taking 30-40 mgs as a normal
oral dose for you, to get a good buzz, i would take 30mgs plugged, or 20mgs. You can ALWAYS take another dose of your drug of choice, but you can NEVER go back and undo a dose, so try to remember that. But its not really that big of a deal, with such a low dose. Plugging opiates can possibly be somewhat too intense for some people, and there is a risk of throwing up. When i first started plugging, i had been orally dosing oxycodone 30mg tablets for awhile, i plugged 30mgs of oxy my first time, and felt great. Then i plugged 60mg of oxycodone (i have done it before, just orally), and got sick as hell- throwing up for a good 30 minutes. This is because it hits you alot faster, and alot harder. But im use to it now, i just dosed 60mgs of oxy about 45 minutes ago, and im just really fucked up (way too itchy, but feels so goood

) lol
