Natural problem solvers, stoners can turn pretty much any mundane task into an adventure. Faced with a problem — running out of rolling papers after the smoke shop closed — and they will craft, tinker, and carve their way to a solution.

There's a scientific explanation for stoner innovation. The psychoactive effect of THC, the main ingredient in cannabis, can lead users to connect seemingly unrelated concepts, according to a 2011 study reported in Psychology Today. That effect could explain the creative thinking that inspired the handmade smoking apparatuses depicted below.
