-Yes, if you go to a local dispensary they will or should know everything about CBG. If they don't, run for you life. Good chance CBG will be sold at your local pharmacy in the near future. Lot of info out there on it and as I've mentioned it's non psychoactive
-The Indica/Sativa myth is that either plant will give you a specific high. There are a lot of factors that contribute to that. Indica is a plant that is shorter/bushier and came from a drier climate. Sativa is taller with thinner leaves and came from a more humid climate. Indica does have more CBD in it. That's pretty much it. And now with all the hybrid plants being made it's impossible to know the actual effects it will have on a user.
