need to pass drug test in two days!!!

Okay guys so I'm a daily smoker. Probably 2-3 grams a day. I just got an interview in two days and my friend told me they drug test and send it to the lab. And they watch you pee. This job consists of working with heavy metals and i plan on quitting. I really need this job and I've searched the thread but i cant find something similar to my situation. Anyone know anything?? I've heard that eating a lot will mask the thc??? Any help would be greatly appreciated!

2 days and they watch you? Seriously bud I hate to be the one to tell u but I think your screwed unless you can pull off the dilution method posted here without the result coming back diluted. First I've heard of pre - employment watching you. Best of luck bud :/
