Having gone through the process of raising money in the past, I'd say the 1 determining factor is if you have some sort of IP that belongs to you that will make the idea work. If you have a patent,then there is nothing stopping you from publishing, but just know that it's strange in the community that this would be published.

As a Reference, my last start-up owned a patent and I believe that my pitch deck is still currently floating around online.

I have never lived in the marijuana industry and never dealt with their VC's do you have friends in the industry that you can reach out to to ask their opinion.

As a general rule, I wouldn't publish anything if you don't have the IP.
