Hi all, hope your doing well. So I started smoking again about a month or more ago and I'm trying to stop but it's hard, I have a vape coming on the weekend so fingers crossed that helps. Anyway with all that's going on I want to get back in shape but as you all know it's hard with asthma and my anxiety but recently I was checking my oxygen saturation and it worries me a bit as it varies from between 93 and 97 percent. My question is would me smoking again be causing this and what other common reasons are there for a lower than normal oxygen saturation? When ever I have been doctors they have said it's all good so I'm a bit confused
Thank you all
