Info (from CANORML) on testing:

Blood Tests Unlike urine tests, blood tests detect the active presence of THC in the bloodstream. In the case of smoked marijuana, THC peaks rapidly in the first few minutes after inhaling, often to levels above 100 ng/ml in blood plasma. It then declines quickly to single-digit levels within an hour. High THC levels are therefore a good indication that the subject has smoked marijuana recently.

How long do drug tests detect marijuana?
http://www.canorml.org/healthfacts/drugtestguide/drugtestdetection.html

There is no simple answer to this question. Detection time depends strongly on the kind and sensitivity of the test employed; the frequency, dosage, and last time of use; the individual subject's genetic makeup, the state of one's metabolism, digestive and excretory systems; and other random, unknown factors.

The basic drug test types and their approximate detection times are shown in the table below.

	Urine	Blood	Hair	Saliva
Marijuana - Single Use	1-7+ days	12-24 hrs	Doubtful	Not validated (0 -24 hours?)
Marijuana - Regular Use	7-100 days	2-7 days	Months
Amphetamines	1-3 days	24 hours
Cocaine	1-3 days	1-3 days
Heroin, Opiates	1-4 days	1-3 days
PCP	3-7 days	1-3 days
