Hi. More than the marijuana, the cigarette smoke may have restarted the pharyngitis. Whether it is infected or not will be indicated by fever, neck nodes and worsening pain. Cigarette smoke destroys the inner mucociliary lining of the throat that harbours a defence mechanism that fights early throat infection. It seems that the contact with smoke occurred without complete healing of the throat from the previous infection (even though the symptoms disappeared), the mucosa may therefore have a reduced threshold to inflammation. The little bumps in your throat resemble the description of what is called a granular pharyngitis. That would explain why it feels a little sore. The smoke may have precipitated the pharyngitis. This can lead to dryness and is a good bed for viruses and bacteria to start an infection. Most granular pharyngitis start as viral infections and are easily treatable. A good oral rinse and gargle with betadine or an antiseptic mouthwash before and after meals for 3 days should take care of this. If you start developing pain, difficulty in swallowing or fever then have yourself started on an antibiotic and anti-inflammatory medications by your ENT surgeon.
