Master Kush is still a Killer Indica
When you are medicating for sleep or anxiety (or both) the best solution for you is likely going to be a good ol' stand-by like this bud. Master Kush is a rather pungent bud with slight overtones of citrus and occasionally even a pine-like taste.
While Master Kush does provide a relaxing sensation and even relieves headaches and muscle pain, it does not have the heaviest cerebral effects of the Indicas available. You can often still function with most tasks while using it and at the same time it will allow you to sleep more comfortably.
Truthfully, a lot of cannabis connoisseurs love this bud because it's a classic and it tastes great.
