Hi I have recently been diagnosed with Emphysema. I dont really feel short on breath my chest just goes tight sometimes and I keep feeling like I have something stuck in my throat. The doctor told me the top of my lungs are scarred I was smoking about 25 a day I have cut back to about 8 eventually I will stop. I smoke cannabis mainly I looked and that can be worse than tobacco is that true. I am only 33yrs old if I carry on smoking cannabis only will I destroy my lungs fast. My neighbour has it bad he can't go down stairs without breathing heavy he smokes 2 50g pouches of tobacco a week I used to smoke 1 50g a week he's 63 will I even make it to hes age if I carry on
