Absolute proof, of course not. Although there is proof of Tilray sending letters to victoria MPs/council members about licensing dispensaries. When they did this they did not say "this is why LPs are better and safer" they told the council why "Tilray is better and safer" Why would Tilray give an opinion and one as biased as that to open discussion in a different city is beyond me.
Tilray has been bashing patients gardens since the get go. There were a lot of things let out once they laid off 50-60 people last year.
