Need help with first time CBD purchase!

18 year old living in Minnesota here. Ive recently come up with worse and worse anxiety, muscle tension, etc… However I just can’t get my hands on a CBD cartridge or something similar, not even when visiting smoke shops with parents, they’re just not sold.

QUESTION: Would I at 18 years old be able to travel to Wisconsin in order to acquire something? I have a valid Minnesotan ID and I’m 18.

Thanks in advance!
