Testing for Cannabis: The Facts
The active ingredient of cannabis - in other words, the chemical within it that gets you stoned - is tetrahydracannabinol or THC. When you get high, you are saturating your blood with THC. It is this that is being tested for in cannabis tests. Tests can detect 50-60% blood saturation.
However - it's more complicated than that. Obviously you can't reach more than a 100% level of blood saturation, but your body can also store THC in fat cells. The THC is still there, although no longer getting you high. Effectively, you can reach 1000% saturation - that is, your body can store 10 times as much THC in fat cells as it can in the blood. Only about 10% of this is lost each day, and if you smoke on any given day, you "top it up" again. What this all boils down to is, unfortunately, THC can be detected in your body for anything up to a few weeks after use, if you are a heavy smoker.
What it basically comes down to is this: if you are a regular smoker of cannabis it will probably take up to six weeks of complete abstinence until you can pass a blood test. Sorry!!
If you only smoke occasionally this time is reduced. One spliff after weeks of abstinence will probably be out of your system within about a week. Here is a very crude calculator for whether or not you can pass a test:
N * 100 * (0.9S)
where N is the number of days you got high in the 10 days before stopping and S is the number of days since you stopped.
If this sum is less than 50 then you should be alright to pass a test.
Please allow me to repeat that this is a very crude sum and I can take no responsibility if you rely on it and fail a test! The basic rules remain - if you haven't smoked for six weeks you're safe: if you've smoked at all within the last week you'll probably fail.
