Yes; if you remember when you test for viruses like influenza or Covid, the nasal swab is in the same area that you snorted the cocaine in to. We don't test for the common cold virus but that too is easily transmitted from that body site as well as the hands that transfer the bills.

Thanks for the question. If any of the users has Herpes simplex or a respiratory infection such as a cold, flu, or Covid, it can spread this way.
