Pot smokers looking for a heavier-hitting high are turning to “Shatter,” a weed concentrate that packs up to 80 percent cannabinoid content. Drug officials aren’t sure how to deal with the drug, a smooth, glassy substance that’s significantly more potent when smoked but is still, ultimately, a marijuana derivative and thus not particularly unsafe.

Other well-known forms include “budder,” which has a creamier, wax-like consistency, and oils, which are golden and honey-like.
