Hi Joshy Thanks for your query. Smoking in any form be it cigarretes or weed is harmful to health and you should stop it immediately.You might find it difficult to leave at first but with time and determination you have to leave them.You can use nicotin patches instead of tobacco smoking , which will help you leave it. Regarding your question if smoking affects virus , no there is no direct effect but ofcourse tobacco smoking affects the ciliary motility of respiratory tract and indirectly increases chances of infection .But how can you be sure its viral laryngitis and not bacterial laryngitis ?Was throat swab culture sensitivity testing done? Continue the gurgling as prescribed by your doctor. Stop smoking Take Vit C tablets. Have plenty of fluids. You can start emperical anibiotic therapy with coAmoxiclav considering it bacterial infection / to prevent bacterial superinfection in a viral laryngitis .Throat swab culture sensitivity testing are to be done. You can take paracetamol for fever if you have. Hope this helps. Update here how you stay. Take care.
