Permafrost Weed Strain Europe also known as “Blue Permafrost,” is a sativa-dominant hybrid marijuana strain  by Rogue Buds. Permafrost is name for its frosty coat of crystal trichomes and fresh pine aroma. While some believe Permafrost to be the love child of Trainwreck and White Widow, others claim it comes from Kali Mist and Trinity Snow. Permafrost’s relaxing effects are balance between mind and body. Larger doses demonstrate the strain’s potency: as sensory detail peaks, attention becomes transfixed, and a full-body calm takes over. For this reason, Permafrost may help patients treating ADD/ADHD and anxiety symptoms, and others report its success in treating arthritis, asthma, multiple sclerosis, and gastrointestinal disorders.
