Keeping drugs in your mouth to allow swallowing quickly when stopped by the police is SOP for both heroin and crack cocaine dealers in most places I have experience of purchasing on the street.
Once swallowed, a pat-down search finds nothing, you wait until the police leave, then stick your fingers down your throat and throw up the bags. Here they are ususally wrapped with cling-film (saran wrap) and as long as you don't wait too long, stomach acid won't be a problem.
