Not for personal amounts of weed. It’s not like these laws stopped anyone from bringing it across state lines when it was illegal in both states. The state police aren’t going to waste their time trying to bust people with an oz of pot coming back from Mass they have much more pressing things to do like not enforce the speed limit on the highway.

Now if you get stopped with a pound of weed bagged out into ounces coming over state lines that might get you a trafficking charge
