Sorry I cant tell 你 for sure but my guess would be tick tacks cuz they are white and look kinda like vicodine.
Also once durning a behind the scenes Lisa 说 that the stuff in the bottles at the pharmacy is sweet tarts sorry that is all I can tell 你 cuz I dont know for sure.
i take vico for pain & whatever they use looks exactly like it, so my guess would be maybe they have some sugar pills made to look like them. it's gotta be something that melts in his mouth cuz he don't apper to chew anything. just a guess!
i do know, like huddybrave said, that Lisa 说 the stuff was sweet tarts, but maybe not all?? would have to be the right shape for us who know what a particular med looks like, & this 显示 does go for accuracy.
