Listed US pot companies' shares are trading on the Canadian exchange (where they have to list, since pot remains a federal controlled substance) for 20X to 72X times revenue. Listed Canadian pots companies' shares are trading on the US exchanges (where they preferred to list, due to far greater investor volume) for even higher valuations.

I'm sorry, but to trade at those valuations, a company needs to have 1) huge future growth in both the near-term and long-term, 2) very high future profitability, 3) impressive barriers to entry and overwhelming competitive advantages.

The highest price to sales for Facebook (FB) was about 25X, for Google (GOOG) 8X, Alibaba (BABA) 29X.
