Try breaking open a bud and smelling the inside. If swiY gets that fresh stink then it should be fine. SwiM
isn't sure what compounds are responsible for pot
's aroma but doubts it's THC itself (maybe tho!) -- it's possible that they are water-soluble though in which case the water could have stolen its scent
But THC itself is not water-soluble, so the high would be unaffected by the leaves.
And nah, swiM doesn't think that anything someone would spray on there would be too toxic etc. If so we'd be hearing about it a lot more
Not saying either that's what happened, but it's at-least worth investigating with the nose
