Gassing is a term used in prison, it is when a prisoner stores faeces, urine, and sometimes blood in a bag; which is used to assault a guard usually during head counts. Usually from a convicts which have a life sentence because they're not going enywhere.
I was a victim of a gassing I my have been exposed to HIV hepatitis A, B, and C now i have to be tested and on anti-viral drugs. and it could take up to three to six months of being on medical leave then i find out if I'm infected.
