The answer is no. As we mentioned before Cannabis a schedule, I drug. There is risk associated since there are federal laws that apply in the sense of border crossing, but the good news is that there is no DEA or Feds parking in state borders just to check if you are transporting drugs. If police catch you in a state where it’s illegal, they might charge you with a civil citation, unless you can present your medical I.D. card. If you cross International Border, then that’s a game, where Customs are involved, and you will be under federal jurisdiction.
