Directional highs: the future of marijuana? The scientific publishing business, social cooling, and an inflatable balloon to help the world lose weight.

Recreational marijuana use has been legalised in 8 US states and there's a boom in consumer pot products. Now you can choose exactly how you want to feel in advance: directional highs allow you to select the specific effects of what you're inhaling. Sold under names like Sleep, Bliss, Relief and Passion, producers are selling precisely measured dosages in carefully calibrated formulas inhaled through a vape pen, giving you control over how alert, active, and sociable you want to be. Mary H. K. Choi has been sampling the products of one producer.
