SDN is not for medical advice.
He/she isn't asking for medical advice...
I'm not sure how many people will be able to answer the question here, though, given how new many of these MJ laws are...
I can't imagine that it would show up on a background check, but that's just my uninformed opinion.
Agreed with blueharbor...the mother already uses medical MJ, there is no change in treatment being asked about, but simply the legal/application ramifications of the MDMJ caregiver license.
OP, I have to say that logically, I don't see it being an issue, but risk-assessment wise I would err on the side of caution. These things are not yet commonplace and if there is any other way for her to get the care she needs, I don't see it being worthwhile. Since you are hoping to be leaving for med school within the next year or so anyway, it may make more sense to spend time
now working out a solid care/support plan which does not require you for the day-to-day stuff, and to set it up while you still
are here day-to-day to make sure it goes smoothly and is set up the way it needs to be. This would avoid the whole issue and possibly avoid time-crunch roadblocks in the future.
That being said, if it comes down, in your opinion, to your mother's health, you may not feel like there really
is a choice, and that's OK too. I hope things work out for you!
