Question: Thank you. I am a cigarette. And marijuana smoker. I am scheduled for a C T Scan angio with contrast tomorrow. I was told not to smoke cigarettes prior to test. May I smoke a joint. Will this affect my Scan? Thank you

I do not advise you to smoke a joint or cigarette. Any kind of smoke is better avoided at least 4 hours before a CT Scan. It will affect the findings of the Computed Tomography Scan largely. Smoking was related to several abnormal CT signs even among those with relatively small exposure. It showed increased emphysema signs and bronchial thickenings.

Let me know if you have further inquiry.

All the best for your test.

Hello, My name is Keyna. I am 33 yrs old. I have smoked for 13 years until recently. My doctor sent me to have a routine xray 3 weeks ago and it came back with changes that indicate COPD with the prescence of emphysema . Naturally, I quit (started Chantix). I wasn t given an inhaler until today when I went back in to insist that something be done about the tightness in my chest and the shortness of breath that I had been feeling since before the xray was even done. My Doctor gave me the inhaler, but now states that I was never actually diagnosed with COPD/Emphysema; just some changes. I asked well what in the world is causing me to feel this way? I was told he didn t know, but would not send me to a Pulmonologist until I tried the inhaler first. My PFT was normal and my O2 Sat was 98%. I have so far taken two doses of the PRN inhaler that I can take q4hrs. I noticed an immediate change upon the 4th hour after the first dose. This tells me that I will be needing this inhaler all the time. What is wrong with me; if it s not COPD/Emphysema? Why doesn t my doctor do more testing?
