PK is one of those strains that I'll always have at least a couple grams of. It is one of my go to Medical strains as I am a patient suffering from Chronic Pain resulting in severe Secondary Insomnia. It's always nice to sit down at the end of the night and smoke a bowl of Purple Kush. As I take my first couple rips I feel it slowly calming me and relieving pain and somewhere around the 2nd bowl is when I call it bed-time! Definitely recommend!
