mickrick Reviewed by mickrick on . "Sprayed" Weed? I heard of people spraying their weed with windex/other aerosol cans etc MY QUESTION isss.... how can you tell if you weed has been sprayed? Signs? (Smell?Sight?Touch? etc..) And I had this weed that after half the sliff was burned the rest of it was very dark brown color (it started off looking like good green weed) and It gives a 5 minute buzz followed by a headache and thats it.
