In PA where I live, marijuana is only legal for medicinal use. But I can drive 20 minutes south into MD and buy it legally for "recreational use".
This is bound to lead to legal issues for people because it's against the law to posses it in PA without a license, and it's also against the law to transport it across state lines.
So I'm trying to stay ahead of the game in anticipation of getting pulled over one of these days driving back into PA with the stuff.
Do I have a valid legal case, considering MD's relaxed laws on the sale of the Devil's lettuce to people like me coming in from another state?

I would be very careful. It's always serious criminal enterprises involved. Guaranteed to step on toes.

Why not buy black market in your own state
Better to risk a misdemeanor over multiple felonies

Don't drive like an idiot.

You have no case. The criminals know the law and willfully violate it. Sue your own state and you may have something, but not based on what you've said. You'll need solid numbers to back up your claims that recreational pot in Maryland is affecting Pennsylvania. Maryland is entitled to sell its drugs to tourists.

utah tried this with colorado and all colorado did was end up contributing to the jail housing codts of towns near their border
