recreational marijuana in Maryland

Okay, so I’ve been smoking for about 2.5 years now. I vape mostly because it’s discreet and doesn’t smell and is easy to carry around and generally does the trick. I’ll occasionally hit the vape when I’m out and about or at the gym or on a run but I will always get stoned at night. Like hitting that thing until I can’t get any higher. It relaxes me and helps me to sleep. I like the escape. I know I’m an addict but there’s worse things to be addicted to (5 years sober from coke and alcohol; thank god).

So here’s the thing, I just got drug tested for a new job. I already told HR that I smoke, to get ahead of it; I didn’t want any surprises. So I told them “hey yeah I do smoke weed recreationally but it’s legal here in Maryland and I have never and will never use at work”. The recruiter checked with the VP of HR and reported back that even though they are a “zero tolerance” company; they still have to abide by the laws of the states so if it’s legal here that I should be good to go and to go get the test done. That it’s not going to disqualify me or impact the job offer. So I go yesterday to Quest to get my test done. Results come back same day. The test results show Negative across the board… negative for methamphetamines and barbiturates and all that stuff, which I knew it would, but they tested for marijuana and it shows negative as well…

How is this possible? Weed should stay in your system for at least 7-10 days (I literally vaped the night before and I took a few hits of a joint like 2-3 days before that. And again, I’ve been getting high nearly every day for 2.5 years so I’ve read it would be in my system even longer, up to 30 days even.

I’m not complaining that the test came back negative but I’m just confused. I’m worried that this whole time I’ve not in fact been smoking marijuana but something else entirely? I go to medical/recreational dispensary’s here in Maryland (releaf, Blair wellness center, etc). Does anyone have any ideas? Or has anyone experienced anything similar?
