How long does weed stay in the blood stream?

And i need to go to a doctor because of a health issue, (i might have a cyst or something)...anywayz my mom told me they do a blood test to find out what it is...can i go to the doctor and him not check to c if i have drugs...or do i have to wait a monthto have the weed clear my system





P.S. this is only my second time doing weed, the last time i did it i had 1 brownie and a couple hits back in september

How long does weed stay in the blood stream?
roughly a week if i remember correctly


or maybe a month it's been a really long time since i had that issue
Reply:If they have no suspicion of drug use, then they won't test for it. The normal blood tests to check your health, that check for blood counts and metabolic panels, do not include drugs.


Don't sweat it. The weed is making you paranoid. He he!
Reply:About 30 days. I've also seen someone pass a test only ten minutes after they used, because it takes about twenty minutes to enter your blood stream granted you haven't done it a month before that.
Reply:The doctor specifically has to check for drug content. If he's checking you for a health reason, it won't show up in the testing.





It's costs money to check for different things in blood - they only run the tests they have to.
Reply:it's probably best to wait till it's gone from your blood stream before going.





does your mom know about it? coz if it's still in your blood stream when you have the test, then she might find out about it.
