How Long Does Marijuana Stay In The Blood Stream
One Month: For a heavy user up to one month, rarely longer. Thc really doesn't stay in the blood stream, rather-it is stored in fat and is considered fat soluble. In fact, that is why it can take so long to get out of the body. The thc has to get out of the fat cells. It does depend upon, as one colleague has noted, the frequency of the use as well as the potency of the drug. ...Read moreSee 1 more doctor answer
Thc in bloodstream: Hunault et al 2000 calculated that high dose (23 %) marihuana can stay in your blood stream up to 8 hours. However cannabis users can have products of metabolism circulating and excreted for prolonged periods of time. Cannabis users are usually identified through detection of 11-nor-9-corboxy-delta9-tetrahydrocannabinol (thccooh) in urine. Thccooh may be detectable up to 3 months. ...Read more
Several hours: I've heard a range of 4-6 hours - but there is some confusion among patients about the much longer time one of the ingredients has been given. Ask the doctor who prescribed. Or probably a pharmacist could tell you more certainly. ...Read more
Variable, but the: Companies that manufacture the tests say that saliva can remain positive for 7-10 days, whereas blood and urine tests are generally negative within 3-5 days.

Up to weeks: The stuff also enters fat cells and may stay detectable for a long time especially if you're burning fat.

Why not be "high on life" for now? ...Read more
Cocaethylene: It depends on how much is present in the blood and route of administration of cocaine. It's half life is 3-5 times longer than cocaine which makes it attractive to drug abusers for a longer high, but also has an 18-25 fold increased risk of immediate death over cocaine use alone. Never recommended. VERY TOXIC!! ...Read more
Usually about 3 days: The most consistent amount of time is quoted as about 3 days or 72 hours. Testing for Cocaine is very unlikely to yield an incorrect finding -- if its there the test will pick it up. The use of freebase and other forms of Cocaine is very dangerous/addictive -- death is a possible outcome of any given use because of the drug's effect on the heart, lungs, and other tissues. ...Read more
I don't believe it: accumulates in the placenta, any differently than any other tissue. Heroin is a very short acting drug, and heroin itself only lasts a few hours. Its metabolites can be found in blood and tissue for perhaps 6-8 hours, and urine tests can remain positive for metabolites for a couple of days. I am not aware that placentas are checked for drugs - usually its meconium in the baby (its first stool). ...Read more
