It's a shame people rip others off. I bought hash a while back, and the guy had cut it with noticeable quantities of molasses. Asshole.
Not true at all, the silica is so small is can attach itself to the tar/THC molecules, that's why it is such a serious thing, because its in the smoke, that gets into your lungs. Get a kief screen and kief some of it, then look at it with the microscope. Tricomes are round and organic in shape, silica is very geometric.
