I am a 57 yr old cannabis enthusiast who is also an athlete, so optimal respiratory health is of vital importance for me. I have not smoked cannabis in over 5 years, and have relied on baking my high grade, organic connoisseur quality herb for health reasons. Over the last few years the thought of vapourization intriged me because of the ability to deliver the medicinal qualities of cannabis quickly, void of combustion. This curiosity led me to purchase a digital volcano. However, after using the vapourizer over the span of a month consuming .5 grams daily, I am experiencing declining repiratory health. My lungs are not functioning to their full capacity, and my throat has a sticky film in it. My volcano is set at 365 F, so combustion is not a factor, but my throat and lung discomfort are causing me concern. I do not dispute that vapourization is a superior choice to smoking, however, my negative respiratory symptoms are leading me to question whether vapourization is an entirely safe mode of delivery. What are your thoughts on this issue? Advice is greatly appreciated. Thanks!
