Meth: IV>Smoke>plugged>Snort>Oral
IMO.
I never banged, or plugged, or oral...and i'm a meth nub (only bought it twice since i got sporadic access to it back in mid-october, bought half grams both times), but snorted i only got a proper full on high once (one out of like...3 or 4 snorting sessions/attempts)....and it wasn't too much bettre than a fat dose of d-amph, smoking it is IMO the point of the shit...i wanna try IV, but IMO if you're not smoking it, its not much to write home about/not all that much better than just high doses of d-amph.
Smoking is ridiculous though...
I've been rather conservative with dosing methinks most of the times i've used meth though, only last sack did i like learn that i was dosing far too conservatively the other times/did proper doses.
last time i used methamphetamine i smoked somewhere in the neighborhood of .15-.25 in one sitting, over an hour, and god DAMN was i high as a motherfucker, my hands wouldn't stop shaking, and my vision towards the end of smoking would like...zoom out when i'd blow a hit out, like i'd blow and instantly my vision would go completely blurry for like 10 minutes....
last time was when i got the smoking technique "right" and started to actually get proper hits though, the other times i smoked i couldn't get anything more than PUSSY hits due to shitty pipe design so i wouldn't get near as high...
protip: when you make a lightbulb meth pipe (they dont sell pipes here, we dont have meth here...), be sure to take a soda bottle cap and screw it on the end of the bulb, then heat the cap up, jam your pen/inhaling tube through it, and cut a carb hole in the cap afterwards, and THEN smoke it. Last time i smoked i did that instead of just putting a pen in my mouth, and inhaling through that...when i put the cap thing on, then i was getting proper clouds every time and killing bowls in just a few hits instead of taking like 10-20 hits to kill a bowl...
without the cap my lungs would literally fill up completely before i could get a lot of vapor, with the cap i was blowing proper clouds of that thick white smoke without even trying...no cap i couldn't get those long 10-20 second hits/inhales, with cap i was getting those with ease.
