I have yet to find a strain that helped with opening my airways and lungs. Blue dream did just that. It also didn't leave my throat feeling bad, which most strains do. Their new patient deal with a free pre-roll made my day. Thank you Monarch for quality service and buds, keep it up. One last thing, their pre-rolls are nicely done also, using RAW papers, and packed full with an individual zip lock bag for each.
