Sativa works for me, too. Quick arousal.
Tea made from calea zacatechichi ("Mexican dream herb") works even better, but it's revoltingly bitter.
For me, though, the best of both worlds is to make an ethyl alcohol tincture of calea zacatechichi and add it to ground sativa. (Let the alcohol evaporate before smoking/vaping it!) The calea adds a bitter perfume to the weed, and stimulates hands-free arousal.
Curiously, the alcohol tincture really increases the potency of the calea tincture. When I use it for tea, I need at least a gram of calea to have a noticeable effect. But when I make tincture, a gram makes enough for a dozen doses!
The catch? Calea really does intensify dreaming, so beware if you suffer from unpleasant dreams.
