It's simple. When it is first synthinsized "extracted from morphine in Mexico, It is in powder form. If you get your tar from pisa's "cartel or other mexican related drug trafficers" it is powder. The powder absorbs moisture very easy because of the molecular breakdown used to make it injectible "vinager primarily". Once moisture or heat is introduced, it breaks down and becomes gooey and bendable or breakable. The more goey the product, the more its been stepped on "cut" in my experience. They may use sugar, baby formula, dr pepper etc.. to cut it. It will be sugary in flavor after this. The powder tar will usually taste and smell stronger of vinager. If you taste or smell sugar, its been cut... Probably more than once. I prefer to get it in a powder form then i huff it down "breathe moisture into it" myself.
