I don't think Paragon can be the key to open that door. First everyone, from politicians to citizens, must change their minds about cannabis. Then laws must reflect that change. Finally, Paragon must provide a secure background to allow the change become real and secure the process.
I think most citizens, both in the US and in the EU favor cannabis legalization. It's mostly just the politicians that are living in the previous century. I think in 10 years most US countries will have cannabis fully legal and in Europe too.
Moreover, voting in several US states in Nov 2016 was in favor of cannabis, and there are ongoing decriminalization process in several European countries.
