Grit weed?

Honestly, I can't tell a thing from the pictures. It looks like normal bud.

 

Kind of hard to tell from the pics mate. I just picked up some suspicious looking bud, looks almost fake but I doubt it is. I am sure your bud is fine, if you start getting bad effects from it, stop smoking it.

 

It might be improperly cured.  Dried too fast with too low humidity.
 
Just a guess though.

 

A few years ago there was a health warning out on weed that had been sprayed with glass powder to weigh it down.
Some bud is really sparkly though...
 
Get something clear plastic, like a cheap salt shaker, and rub it hard against that sparkly stuff on your table there.
If the plastic gets all scratched up... you've got a problem
 
 
 
 
The lines on the photo are from your light. Some types of lights (like HPS) pulse. Our eyes don't tend to see it, but it is very pronounced on pics.

 

rub it up against a cd or dvd....see if it scratches.

 

Personally if I had to question it, I wouldn't smoke it.  You been smokin for a few years now, you know what bud is supposed to be like. The alleged kief that has falled off the bud does look questionable in these pictures for sure, but it's hard to really tell not being in person.  It definitely looks of a sandy texture.  Much larger than the average trich head.
 
I like the scratch test idea a lot. Trichomes won't scratch.  They will just smear and stick. 
 
Possibly sugar crystals?  I have heard of dealers misting their buds with sugar water to make it more frosty and sticky.

 

yea rub it on a cd for scratches... grind it up and run ur finger through it to feel for grit.. it will be obvious

 

 
Was gonna say the same thing.... I read a story about some weed getting sprayed with glass also..
 
EDIT: Yeah google that shit.. It's exactly what Better Life said. Its on some other forums too, people do it to add weight to the weed.
 
And they wonder why more people want it legalized so they can grow their own...

 

 
It looks like good weed too, doesn't make sense.
 
I would throw it out in a way that destroys it so you aren't tempted. If you are still going to smoke it consider using a cig filter, though most agree it takes away from the high you will know it's not letting anything through.
