Hi all--my first time posting! Feel kinda wierd not contributing and just asking for info right away

But anyway, here's the situation...
In order to get some $$ from a trust fund I have to "prove 6 months no drug use" At first I was like no problem because I quit weed a year ago, then started looking into the different drug tests available. I used some dexedrine, probably something like 20mg (no more than that) once a week for a couple months--I didn't think the tests would include legal substances, but then again its just the class that dexdrine is in.
So I'm going to try the hair wash methods described elswhere in this section, worst thing that will happen is I have to wait 6 months for the money.
Anyway, a more specific question I have is, if the trust says "must prove no drug use for 6 months" - does it matter if I go through a lab to have a hair test or can I buy one of those home kits? I haven't got the papwork in my hands yet, but from what I understand thats pretty much all it says.
So anyone know any legal stuff?! Those lab tests are hella spensive like $350 where I live and a home test is like $100. If the trust doesnt say exactly how the test is obtained, then does it matter?!
Sorry for the wall o' text
