Website to tell what type of weed you bought?

I have heard of a site that has all the bud and the pictures and also like cocain, dxm, and drugs like that and shows pictures and describes them...Does anyone know a site like this, I am trying to find it...

Thanks,
Tom

www.erowid.org has information and images on drugs and the like as well as some bud shots.

http://overgrow.com/edge/gallery.php has just marijuana pictures.

http://www.smokersguide.com has pictures of lots of strains from Amsterdam coffeeshops.
