Provided you have certified diagnosis and everything. And does proof need to be by local doctors or are US docs papers alright too? (Reason I'm asking: traveling to Europe and using CBD oil for otherwise debilitating illness. Literally can't get out of bed without it.) In general, what are the rules in carrying such product (in small quantities for personal use and with all paperwork) from one EU country to the other? Tried to read about it but got lost in a ton of regulations, figured it'd be better if somebody has firsthand experience. Thanks
