Im 42 yrs old and havent smoked pot since I was in my teens. 7 months ago I started smoking again. At first I smoked a little but progressed to several packed bowls a day. I was fine for a few months, but out of nowhere it started giving me mini panic attacks. I continued smoking until I had a full blown panic attack about 2 months ago. I tried to quit but it was hard and I relapsed for a couple weeks. Im currently on day 18 of no smoking. I had the usual withdrawls and anxiety the first week. But im still having anxiety. Its mostly with my breathing, I feel im not getting enough oxegyn. This feeling is not constant but comes on fast. My dr prescribed me lorazapam for it. It helps but I dont want to keep taking it. My question is..can this anxiety be permanent? Has anyone heard of this happening? I just want my old self back.
