Out of state MM

I live in Mass, which as we all know does not allow the use or possession of medical marijuana. I was curious, say I lived out of state, got accepted, then moved back to Mass, would they discontinue my status as a medical marijuana user?

Just so you know, I have asthma. I get it really bad sometimes and marijuana actually helps alot. It helps so much that its almost better than an inhaler at times. Ive had attacks where I took a single hit and i could breathe again.

we arnt the ones u have to prove that u need MMJ.

Every state is different.
Only Montana officially accepts other state's MMJ cards.
Many California dispensaries will accept out of state recommendations.
In Oregon, you must be an Oregon resident with Oregon I.D..
In Washington, you only need a recommendation from a Washington licensed doctor. This is probably your best option, but I'm not sure what good it will do you.
