I've heard about Emerald, they're very medical focused. Aurora and Tilray are also good west coast companies. I've also heard Canntrust, Aphria and Cannimed making good oils. I've never tried any of them btw, only from tweed, I only know this because I invest in the mj sector lol.
Good luck and for sure, i'd love to hear your experience.
I had a good look at Tweed, there are a few things from them I'd love to try but given my experience with BC bud over the years prior to medical herb I want one foot in over there wherever else my second LP is from, lol. I'll shoot you a line once I've tried out the CBD I ordered. Smart investment though, if I had spare funds I'd do so too, it's gonna be a huge market here in Canada
