Hello I share your concern. Sore throat or inflammation of the throat due to smoking of weed or infection (which you have mentioned as throat bumps) are very much treatable with anti inflammatory or anti-allergic drugs. I would advise you for warm saline gargling 2-3 times a day. you can take acetaminophen and levocetirizine group of drugs for symptomatic relief. In my opinion you should visit a ENT specialist or your GP for physical examination of the throat and prescription of antibiotics if need be. Meanwhile keep on doing gargling with warm saline water and avoid smoking until it heals completely. Hope I could answer your question please feel free to ask for further clarification, I will gladly answer you. Best wishes
