I have quit smoking after switching to vaping. To be more specific I’m a cannabis ex-smoker who switched to dry herb vaping where you heat raw flower or concentrates up until the cannabinoid oils vaporize but not so hot that things combust into flame. Before I switched I was having issues with coughing up black tar mucus flem and some wheeze in the lungs. No more of those problems, and I can actually taste the terps and subtle flavors now.
