How long does weed stay in the blood stream?

here's the thing i just smoked January 13, 2008. 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

I've heard it depends on how much you smoke, but that aside, the most common time frame I've come across is at least one month.

Reply:the length of time marijuana stays in your systems varies by a number of things such as amount smoked and your body fat





30 days is a good answer as within that amount of time youll be good





if you have only smoked one time and have a relatively active lifestyle after just 1 or 2 weeks you should be good





however if your going to have medical test done they may not even test for drugs
