How long will one hit from a blunt stay in my system

nope
 
length of time varies, why take the risk

 

Yeah. One hit from a blunt and it will be out of your system in 24 hours. 

 

Weed generally stays in the system for up to 30 days, and if they due a test by hair, it may even be longer.

 

one hit? is that even going to accomplish anything?

 

 
Don't listen to this guy. That's if you are a heavy smoker and have smoked for weeks/months on end.

 

 
it could accomplish paranoia that he might fail an upcoming surprise drug test

 

 
It will if you have some good weed.
 
IDK what you get, but I take little one hits from my pipe and get pretty high. Granted I only smoke at night and maybe once a day.

 
It's one hit, he's not gonna fail. It will be out of his system in 24 hours.

 

yeah but one hit from a blunt? whats he gonna do, light it, take a hit then put it out? sounds pretty dumb to me. and blunts are like potato chips anyway. you dont just simply take one chip(hit).
 
so my answer is no, dont do it.

 

 
He could be with some friends who are gonna smoke some with him.. Half way through take a fat ass rip. 
 
But I agree that blunts are like chips lol.
 
My answer: Yes he will be clean and yes he should smoke. 

 

If you smoke it can last up to 3 months. It varies by person. You should take your own advice. Links

Lol I don't care what those links say, one hit will not stay in your system for 3 months. I don't care how much fat you have on you. One hit will be out of your system in max of 48 hours.
 
And the bottom link is not counting hits, they are counting it in sessions. So yeah, I could smoke for 2 hours straight rippin bongs, and in that link it would only count as 'one time use'. 1 time does not mean 1 hit.
 
If you had a session once, then yeah it could take up to 5-8 days, but we are not talking about sessions, we are talking about single hits. Very different.
 
And seriously, get some better sources... High Times and Pass Your Drug Test? Lol, very respectable sites.

 

You are just mad you were proven wrong LOL. Look it up anywhere you want. Up to 90 days. Everyone is different and different variables often occur. 1 hit is still enough to show up positive on a drug test. We don't even know what type of drug test(hair, saliva, urine,etc)

 

 
Please provide me with a link that says 1 hit can stay in your system for up to 90 days.
 
You have no idea what you're talking about.
 
And it's a urine test, the most common form of a drug test. There's another thread dedicated to hair tests. 

 

Don't do it. The drug testers are waiting around the corner.

 

I don't think I could possibly find that result since Marijuana is still Federally illegal thus tests haven't been approved. I have already posted links supporting my claim(marijuana can last up to 90 days in your system), you are the one that has no idea what they are talking about. 

 

 
You are entirely missing the point. Yes, marijuana can stay in your system for quiet a while, but that statement does not differentiate between single hits and long-term smokers. 
 
Everyone knows MJ can stay in your system for a while. But one hit (read that as many times as it takes for that to sink in) will not stay in your system for 90 days.

 

I am glad you are a Doctor. Please tell me how much you know on cannabinoids in the blood stream. I am so enthralled by your knowledge. 
 
Like I said before, everyone is different, everyone reacts different, there are many variables.
