How long does weed stay in your blood stream?

I might get a blood test soon, how long does weed stay in your blood stream???

thanks

i need to know the same thing

I think if you're a light-moderate user it stays like 72 hours. As for the more heavy users, I have no idea, longer I'd imagine, but I don't see it staying longer than 2 weeks in your bloodstream if you stop 2 weeks before the test. I'm not completely sure though.

I would also like to know how long it stays in your system.... I was always told 30days.

THC level depends on how long it stays in your fat cells, I heard 29 days, if its ass kicking ganja, your not gonna pass a piss test

which is really not fair compared to the harsher drugs,
They have more effect on you, in an overall view, yet stay in your system for a short period of time, compared to a bagadope

:smokin:

I think its 4-6 months until it goes completely out of your system but im not 100% on that.

The Cannabinoids are what's in your blood, not delta-9-tetrahydrocannabinol, although the cannabinoids that are tested for are refered to as THC.

Depends on many factors - how long you've been smoking, how much and so on.

What's the bloodtest for, if you dont mind me asking?

If it's not for a drug test, you have NOTHING to worry about.
