will I be able to get cannabis in Russia using your service?
That is quite a long shot. I really do not think that will be possible in the foreseeable future. Paragon will start with the low hanging fruit, the countries that already cannabis friendly.
Well, in the long term you should be able to get cannabis everywhere thanks to paragon work and other pro legaliation companies. But can you by directly from paragon to get some weed in russia : no.
