I am a moderate to severe adult-onset, non-allergic asthmatic. When I started about 5 plus years ago using cannabis for my chronic insomnia (I have since developed chronic pain which I also use it for) I knew smoke was a non-starter...even second hand smoke makes my lungs spasm. After one difficult to use table top vape, I discovered the Magic Flight Launch Box. I was a regular user of the MFLB for several years until it started giving me a nasty cough each time. I even had the MFLB replaced with a newer unit, but to no avail. I learned how to make tincture and cannabis infused coconut oil. So for several years I was switching between tinctures, coconut oil, and random dispensary edibles. However, my tolerance went sky high (pun intended). I also have several concentrate vape pens, but use them sparingly as they cause me to cough. Fortunately, even though the vapes lead to coughing, I have not had any serious asthma complications from them. About 2 months ago, I got a Flora flower vape pen with the idea of getting my tolerance down. To my pleasant surprise, it is very smooth...rarely any coughing or lung spasms. It is a bit messy to load, but otherwise a nice device. So the Flora is now my daily routine delivery system and I use the tincture, coconut oil, random dispensary edibles much much less. I also appreciate the quick pain relief with the vape pen as opposed to the edibles.
FYI, I feel my lung function, which still crappy compared to a normal person, has NOT gotten any worse from my vaping. Since I moved to Oregon nearly 4 years ago, I am having fewer bacterial asthmatic bronchitis episodes. I do get viral asthmatic bronchitis flare-ups, however : ( .
