blood tests

how long after you smoke can it be detected in a blood test?
The last time I smoked was on 4/20

I think it's like a week or 2. You should be fine. :thumbsup:

Lorax you are wrong. I see you are new to the boards today but try not to guess in the drug testing forum. People's jobs, freedom, or children are sometimes at risk.

For most people it is about 72 hours or less. Short window of detection but there is nothing you can do to beat the blood test.

ok good. thx

Maybe you should be the one that should be more careful. Do you know if he's an infrequent or frequent user? ;)

Cannabis is detectable in the blood for approximately 2-3 days after use in an infrequent user. Frequent use can be detected in the blood for approximately 2 weeks.

Erwoid has good info but some of it is wrong, like the detection times. It also says urine is up to 30 days. I know plenty of people on here and in real life that take longer than 30 days. My answer is based on multiple sources, not just Erwoid. I like to be thorough and not put all my eggs in one basket.
