Government job with MMJ recommendation? If I can pass a drug test, can they deny me?

Good evening everyone,I want to get a MMJ prescription but I am worried about getting a government job in my future. I am currently studying civil engineering in California and chances are that I'll eventually work with the government. I am wondering if getting a recommendation (Not a state card) will be visible in a background check? I use marijuana almost every day and don't plan on stopping even if I don't get a doctor's recommendation. It relieves my migraines, helps me sleep, and heals my soul after a long day's work. But, I've been reading tons of forums and finding very ambiguous answers.

So here's what if really boils down to for me: if when looking for a new job (probably 2 years from now) I prepare by detoxing my body weeks ahead of time and pass any drug test, will they have ANY way of finding out that I have a MMJ recommendation?? What about 20 years from now if I don't have the rec anymore, will it still be somewhere deep in my records?

Last, I would like to hear some stories, if any exist, about people who were denied work based on their MMJ rec. If so, were you denied because you failed a drug test or admitted to having a rec? or is it because they somehow found out? Thanks in advance!

1. No, it wont be in a background test, pay for the doctors visit in cash. It will only be on file with medican or wherever you go.
2. It might take longer than a few weeks to remove thca for heavy smokers, it's stored in your fat cells, fatty.
3. Just be thankful it isnt dispensed by a real pharmacy those corporations sell information of what meds you've ever taken to insurance companies.
4. In 20 years you'll likely be dead from refer madness. Or more likely it will be legalized.
5. Don't show up to work stoned or drunk employers frown on such things...also because I don't want to live in fear that you've engineered something I use.

Civil PE, here... Let's just say you're good to go. Just don't go advertising it to your boss or anything stupid like that...

Don't mess with "detoxing"... Get some Dr. Greens Agent X and "piss" confidently. Works like a charm, and you don't have to sweat bullets wondering if your clean.

Also, a quick recommendation... Don't take a government job straight out of school. Go out and work in consulting for a while, THEN get that gov job if it's still what you want to do. As someone who works in the industry, I can tell you we get frustrated when the people "regulating" our projects have never actually stepped foot on a job site.

Thanks guys I appreciate the straight forward answers! No need to worry fungus, I'm a responsible toker haha
and thanks for the tip spicy, I work for a gen contractor right now and I for sure don't wanna work for the government at first!
