Low
Well it goes up to 900 so you can decide
Low
It's usually around 50ng/mg. It may be as low as 15-20ng/mg though.
There are test to determine the THC content in weed. THC is the main ingredient in weed that creats the high. However, test are complicated and require use of a lab. A general way to tell potency of weed is by looking at it. Higher consentration of THC will result in darker weed, 'crystals' on the weed itself, and increased odor and 'stickyness' to the weed, etc. while if looking for low THC amounts, look for many stems in the weed, etc.
how long will benzodiazepine show in urine test
The prelim test is an antibody test and just gives a yes or no answer and can caused by other things than cannabis. The lab test will give a concentration of THC-acetyl alcohol (what they test for) in the urine after 37 days the levels will be very low.
Urine concentration can be measured using a urine specific gravity test or a urine osmolality test. These tests help to assess the amount of solutes in the urine, which reflects the kidneys' ability to concentrate urine. High concentration levels may indicate dehydration, while low levels may suggest overhydration or kidney issues.
Pretty low.
If you haven't smoked for 74 days, it's likely that THC has cleared from your system and you would likely pass a urine test. However, individual metabolism and other factors can affect how long THC stays in your system, so it's not guaranteed. Consider taking an at-home drug test to confirm before a formal screening.
THC is fat soluble, so the key to getting it out of your system is getting fat out of your system. You're on the bigger side of normal in the weight department, which is alright, but you are a relatively heavy user. If you exercise a lot, eat a low fat diet, and drink lots of water, it will be gone in 2 1/2 weeks. If you sit around and munch on stuff all day, then it could take you a month to be safe. Don't drink a ton on water the day of your test. If your urine is too clear, it will register negative for cannabis AND urine. That is, it will be more like water then piss and you will fail. Also, only use urine from mid stream, the urine at the beginning and end is more concentrated. Final note: I'm pretty sure that the blood test for cannabis is expensive and ineffective so it's hardly used. THC also is only in the blood in large amounts a few days after you were last high, so they will most certainly use the urine test.
None of that actually lowers your THC level. But if you want to pass a urine test, drink a lot of water 3 days leading up to the test.
No. They can only dilute urine. Drinking a large amount of a diuretic (coffee, cranberry juice, etc.,) on the morning of the test can dilute the urine enough to get below the threshold which gives a positive result. See Erowid.com
