Whenever I go into a Goodwill/Savers/Salvation Army store, I see shelves full of old Pyrex and other borosilicate glass cookware selling for $1 a piece. Moreover, it's not hard to buy lab equipment out of a catalog (or online). Considering the profit margins on crack, I have a hard time believing that buying beakers ($5-10 each, in bulk; less for student-grade) "had a substantial impact on crack production".
