although ive dabbled in DIY almost my entire vaping career, i never really put the effort in to be a master. ive only got a handful of mixes that are decent. so, needless to say im no pro with additives. all i do is add malic acid to my fruits and vinegar to bakery or tobacco juices. usually EM gets added to both, but not always. maybe i should always add it to everything, like some people do.
