Close. The drug 'molly' (ecstacy), frequently a thing used at raves. Side effect includes grinding, chewing, and sucking with the mouth (there's ca slang tlermd for agit,ng I forgot)hink, causing bruxism. It can be so bad the lips and tongue bleed and teeth chip and break. So the pacifier is there to alleviate and prevent the spasms and urge of that.
It implies Pacific Glow is a rave druggie.
