Well to start off, I doubt your bud was laced. Nowadays it's just not as common for someone to lace bud, it's really not likely.

Also, your "sparkles" are normal, that's THC just glistening hah, it's probably good bud, without pics (and maybe a smoke ) we can't tell, but it sounds like you had a weird reaction like a nitrous high But try it again? If the same reaction happens then you know it's the bud, but I'm doubting it?

Pics would help and a second try!

peace
