When stoned, is it normal to have blurred vision and hearing?

Not sure, depends on how hard they are throwing the rocks

Yes. Many things can happen to your senses when you're stoned.

Oded here, firstly, Dentist. Dude you gotta take it down a notch. No need to turn up the volume of anger and condemnedment. I'm not saying go for drugs but cannabis is all natural unlike other stuff that is synthetically made. And secondly, O.P. it's totally normal. Just fly with it.

Oded....out

Your smoking shit stuff. Smoke clean hash.
