Though often pegged as an even hybrid, Purple Sage in fact appears to have a sativa/indica ratio of roughly 35:65. It's believed to be a descendant of SAGE and an unknown purps mix.
The high hits both head and body, mixing creativity, euphoria, mental focus, happiness, and drowsiness. Though THC levels are somewhat modest, reaching 16% in publicly available tests, Purple Sage is a pleasant choice for part-time tokers and other users with low tolerance.
It can be used to treat depression, anxiety, nausea, chronic pain, insomnia, and stress. But the available information suggests CBD levels are very low, less than 1%, which means Purple Sage isn't the best choice for treating conditions that are relieved with that chemical, such as severe epileptic disorders. Sweet notes of sage and lemon dominate the smell and flavor of this strain, while the buds are light green with brown hairs.
The only widely reported adverse effects are dry mouth and dry eyes, though others may be possible.
Purple Sage is popular enough among those who have tried it, but it definitely isn't widespread. Colorado is probably the best place to look for it.
