It's actually quite good advice.
Yep, so let's summarize.
You're a Medical Marijuana card carrier you probably got by lying in the first place.
You smoke weed multiple days per week.
You're trying to figure out how to cheat and lie your way through a drug test to work for a company.
No, I don't think you'd be the kind of employee most are looking for..
Man up and take the test straight up.
