In my #scifi book Glory on Mars, settlers take cannabis seeds with them. It’s not a big part of the story, but at one point they need something to perk up their appetites and sooth despair – these are permanent settlers, not astronauts. I’m no expert on pot – should they grow it in a Mars colony? What strain should they take? BTW – I don’t let them smoke. I’m a volunteer firefighter – smoke is bad.
