nothing. he just paranoid. actually the shop owner also make pan(india special). so, the chemical color also is red. he don't know what was that.anyway thanks for rapid reply.
And the chance of it being blood is probably almost zero and even if it was blood why would he drink it? I ask that some critical thinking be done in this case. But I also agree 100% with what you have been told.
HIV does not transmit from outside its host
is 5seconds enough to die the virus outside? so no need to worry?
Once HIV virus is exposed to the air it immediately becomes inactive/uninfectious, so your friend had no HIV transmission chance.
No chance of contracting HIV the way you described.
