What Are Effects Of Snorting Oxycodone, Oxycontin And Opana On Lungs?

Hi, I use to be addicted to oxycodone and oxycontin and opana. Also take alprozolam now for my anxiety orally 1 - 1mg a day. I am a recovering addict. Sober now for over 6 months. I still smoke cigarettes.. started that when I was 14 I am now 28yo. I was a very heavy drinker in the past. I would bienge drink. So much I would black out. I have been sober from that for 2 years now. My Question is, I use to snort these pills. Over 5 or 6 a day for years. What effects or damage did I cause or may have caused to my lungs and heart and other organs and circulatory system and/or nervous system. By the intential insuflation of these narcotic pain killers? I am worried about long term and what may be happening now. I have no signs of anything I feel healthy and great actually. No breathing problems or nothing just a little nervous now.
