I've been a smoker for about three years now and I'm constantly paranoid about the future of my respiratory system. I have been battling anxiety for as long as I can remember and smoking just makes me nervous now a days. I've read that vaporizing provides a cleaner, clearer effect which also benefits health. I just want to prevent the hacking cough before I get it and comfortably enjoy my herb without fear. So i'm looking for some guidance on which vaporizer to buy because I'd really prefer if my first would remain functional and enjoyable for a long time.
