Thc doesn't stay for a set number of days.. It has a half life.
Threshold doses for psychoactive effect are not that small...
And blood tests would be used in the field over u/a or saliva and sobriety test
very true. but if somebody does thc its in your system for 28 days . so 27 days later after you go into a party get second hand from friends smoking . you take a test and fail . idk if that little bit would show up . possible though they need to change the test . its hard to even drive any where somebody might be smoking in a car in front of you and get caught at a traffic light . and smell that good stuff burning depending on your tolerance could get light headed from it .
think about this logically..
say you somehow inhaled a shit ton of vapors.. it gets absorbed and enters your blood stream, (say smoking an actual joint, in roughly 10 min peak concentration occurs at roughly 150ng/ml... ) its now being circulated through your body. it doesnt just stay circulating. without getting all fancy, obviously some crosses blood brain barrier it gets metabolized and excreted in feces, urine sweat etc.. eventually-within ~8-12 hrs none is left in your blood
in this time frame metabolites are building in your urine
thc then has a half life (terminal not really mattering here) in your body.
for example 20mg doses of thc orally over a period of several weeks as in marinol are unlikely to test positive beyond 118hrs.
if you smoked half a gram with an avg of 20% thc of dank bud last time you smoked
(.1 grams of thc)
with a bioavailability of about 20% through smoking .. only 20mg of thc entered your body.
you can pass a urine test smoking in a couple days
and doesnt take days for it to show
if you feel like edumacating yourself

lets try to look at this from a logical or scientific perspective.
thc has an initial half life of about 4hrs...as low as 2, as high as 6 depending on yiur body and lifestyle, in normal healthy people ie no issues metabolizing........ and a terminal half life about 30hrs. this is due to the high logp of the drug aiding in absorption to fatty tissue. and why heavy daily users can have a harder timecleansing. heavy is somethinglike a 1/8-1/4 of bud a day to yourself , not just smoking daily but attempting to stay saturated...
now...
"an occasional or on-off user would be very unlikely to test positive beyond 3–4 days since the last use, and a chronic user would be unlikely to testpositive much beyond 7 days,
it may only be detectable insaliva/oral fluid for 2–24 hours in most cases.
Cannabis is detectable in the blood for approximately 12-24 hours, with heavy/frequent use detectable in theblood for up to 7 days (its on and off as they hover along the cut off)"
jacked from a relatively unbiased drug detection discussion/site
as you can see, the curve starts tobuild with heavy users, but the quick half life is apparent....
, if little is stored in the body keepingyou hovering along the cut off it leaves relatively soon
now if you smoked half a gram withan avg of 20% thc of dank bud as the last time you smoked
(.1 grams of thc)
with a bioavailability of about 20%through smoking .. only .02 grams of thc entered your body.
..note this is not including a priorsmoke session...
the test has a cut off at, .00000005 grams per ml.
not total in your body.
this means that after *24hrs having an avg metabolism and averagehydration you could pass.
i dont feel like doing math, but total in your body would be less than the cutoff after *48hrs having an avg metabolism!. your piss, which again is not total but concentration per ml, will be clean after *24
its the terminal half life that becomes a problem. and really what these supplements aid. unless truly a single smome session and none prior
in my line of work, i get drug tested often.
i documented a drug test on riu for personal reasons where i
smoked half a gram ~40hrs before testing and passed,
here i actually did some relativelyextensive calculation... i smoke a few times daily...currently a light-medium user. a few times a day totaling 1-2 grams normally. i couldve gone alot sooner but i figure best to be cautious. im sure my calculationshave been wrong before...i just cant remember such a time
* note that these are rough andgenerous estimations, more for info
exercise and stay hydrated to flush. night before and morning eat a big meal. still stay hydrated.
good to go
