[|AI|]  Thanks for your question on Chat Doctor. In my opinion you should consult pulmonologist and get done1. Chest x ray2. CT thorax.3. Bronchoscopy and BAD(Bronchoalveolar lavage) analysis. Cannabis smoking can cause particles to settle in alveoli. And on long run can develop lung infection and lung cancer. So, chest x-ray and CT thorax is needed to rule out these possibilities. Bronchoscopic evaluation will be helpful in removing particles. You can do therapeutic BAD to clear airways from particles. So consult pulmonologist and discuss all these.
