Never been in legal-troubles personally, but one of my best friends
- (may have been ;0) Transferring marijuana between two states' colleges in the US, while a college student,
- was setup and, while returning with product, was surrounded by cruisers and a K9 unit. Once confronted, he panicked, and nailed his own coffin shut,
- had to serve about a month or two for trafficking or whatever the hell the charges were (at the time of arrest he had product in one large single parcel, but had a scale/tons of bags with him - he lost his nerve/was unaware of how to handle such a situation, and put himself in a place where his parents' (obscene) amount of $ towards lawyers couldn't keep him out of jail, despite it being pot-only, and nothing too large (couldn't have been more than half or a whole key on him at the time, unsure what amounts he may have admitted to during the stop tho)
He served his little sentence and, upon finishing it, he transferred from one of the schools to the other (he transferred to the school he was supplying). He completed his degree in a finance-field (sorry, cannot be more specific for reasons of his anonymity), and is currently doing great work with one of the biggest firms in his industry. This same firm had him as an intern *during* college, like a year after his arrest, and was paying him crazy cash while he was still in school.
While I know he was shitting bricks about his future, once he actually spoke with the company he'd been aiming to intern/work with, he found they didn't give a shit about it. Very likely due to the fact he was a non-violent, drug-only offender (pot-only, to boot), but I should stress that the firm he works with, and his position in it, is very highly regarded. He's doing about the "best", in at least a work/employment setting, than most of our peers (many of whom are doing very well themselves).
It depends what you want to do, and what the charges are relative to that.
(not my friend, obviously)
