I am wondering.........my friend never smokes weed but 2 weeks ago had about 4 hits and then fell off a ladder at work on Saturday and now his blood is being tested for drugs. Do you guys think it will show up? This is terrible especially since he doesn't smoke only on a whim.

BE REAL HERE. IT IS VERY IMPORTANT TO HOW I CAN ANSWER YOUR QUESTION.
DOES HE ONLY SMOKE ON A "WHIM", OR DO YOU SUSPECT HE SMOKES MORE, BUT NOT AROUND YOU?
IF HE WAS A HEAVY SMOKER BEFORE TIME SAID, HE MAY BE IN TROUBLE.
IF HE DID JUST TAKE A COUPLE OF DRAGS, IF THE THC IS STILL THERE, IT WILL BE MINUTE, AND IF IT'S LOW ENOUGH, IT CAN, I REPEAT CAN, BE PASSED AS BEING AROUNG SMOKERS IN A SMALL ENVIROMENT(i.e. BEDROOMS, CARS...)
HOPE I HELPED SOME!

Lets just say I definetely know that he just took a couple "drags". I'm positive of that! So you are saying it would be a small trace if any at all, you think?
