I know exactly what you're talkin about.

I got a bag a couple months ago that was a semi-dark green, completely covered in crystals.. I mean, it looked awesome.. I couldn't wait to smoke a bowl of it. But I was very disappointed after smoking cause it really didn't get me that high.. a slight head change, but that's it. I've smoked creeper weed before, but this was def. not it. That bud sucked.
