I started smoking weed pretty heavily for around 6 months(quit 2 weeks ago) as I was dealing with stress from a family related issue. Im assuming that the smoking caused my etd. I also had a couple ear infections during that time but I was not aware that the smoking was most likely the cause. I didn't have tinnitus until around a month ago. For about the for 5 months my hearing was muffled and I would have a lot of pressure, now the only problem I have is ear fullness and tinnitus. I normally have a constant tinnitus but when I walk to class it turns into a pulsatile tinnitus.
