First Pass metabolism, PKA and Absorbtion
The reason PH affects how pills (and any drug for dat matter) cross into your system is the PKa of the drug
Amphetamines PKa is about 9, ie, it is a weak base, (weak meaning it doesnt ionise fully, unrelated to how basic it actually is).
PKa is the Ph at which a drug will have equal concentrations of ionized and unionized drug
EXAMPLE
pka of 9
at ph 9, methamphetamine (MDMA with assumably a similar PKA)
Methamphetamine Hydrochloride <=> Methamphetamine(-) + HCL(+)
PH's OF DIFFERENT BODY COMPARTMENTS
Blood 7.2 - 7.8 (different areas, its not that variable)
Colon 7.0 - 7.5
Milk 6.5 - 6.7
Mouth 6.2 - 7.2
Stomach 1.0 - 3.0
Sweat 4.3 - 4.7
Vagina 3.4 - 4.2
Urethra 5.0 - 7.0
Now, the HIGHER the PH of the place MA is dissolved (more basic) the better it is going to be absorbed because only the unionised (left side of the equation) form of the drug can actually cross into the blood stream. Obviously the stomach is shit because its too acidic, some will be bound by protein (specially if you have eaten) but in general it is absorbed in the ileum and small intestine.
ok, in the ASS is a lot better, however, painful, the nasal membrane is fairly efficient but also painful and i usually wake up with the back of my mouth feeling burnt. like... literally burnt, do you guys get that? it sucks,
anyway, basically fuck all of amphetamine is actually metabolised. actual amphetamine isnt metabolized at all, but MDMA is metabolized slightly by the cytochrome P450 system using CYP450 2D6. But this is not a great amount anyway, technically.. if you drink your pee im sure you would get high again... but thats not something that im very willing to do, but i know someone who tried to boil his off... and that turned out badly cause it stank out his whole kitchen.... badly...
anyway, basically PH affects absorbtion STACKS, and its not really to do with first pass metabolism (this means metabolism which occurs due to the stomach and small intestine passing straight past the liver)
what i want to know is if MDMA can be absorbed sublingually? like.. by holding it in your mouth, because i know it would taste like absolute shit, but hey, less painful than shoving a pill two knuckles up my ass, even though i got pretty fucked up from shelfing pills it not something i really wanna tell people
but yeah, i chewed a pill into chewing gum once, and i was so fucked up i dont remember most of the day, so perhaps that would be a good way.. im gonna try it at digital. chewing it with bicarb would make it even better, maybe improve the taste slightly
Also, the ionization thing affects re-absorbtion from the kidneys/bladder, which is why you alkalise your urine to get rid of aspirin (a weak acid) quicker. So im pretty sure if you alkalize your urine with URAL or some other over the counter urinary alkalizer then your pill would last longer, (ural is sold for urinary tract infections so u may get some dodge looks if its sitting in your cupboard)
oh and one last thing, most of my friends know i have plugged, no one really cares, im not embarrased
anywho, hope this helps you all save money and get fucked up
