White widow is a potent weed. It develops many white THC crystals hence the word white, and is very expensive. The reason for its name of widow is very dangerous. You take a dried up black widow(not to old though) and place it under the bowl in a pipe. The weed sucks out the hallucinogenic properties of the black widows venom. This is highly dangerous, and i highly do not recommend it. It does deliver an amazing trip but the chance of fatality does not make it worth it.
