Right the only thing relating to drugs is the box (narcotics, which was unchecked for me). You see, I'm a fairly constant user, and I smoked a blunt about 3 days before, I got my blood drawn for the green card. My guess is that that box is there if you have been convicted of a drug-related felony or something, I honestly don't know. I passed, and honestly, with the amount your friend has smoked, your friend shouldn't be worried about it. I say don't worry about it.
