As cannabis turns mainstream, contemporary and cleaner aesthetics of pot products start being reflected in their designs. Here is a pick of 5 minimal, hand-made in the USA, smoking pipes worthy of a special place on the shelf. Smoking devices often have a sleazy \u201cpot culture\u201d look to them: pipes with images of weed leaves, psychedelic artwork or some Rastafarian cultural reference. As a result, it began reflecting a marginalized "pothead" imagery to these products, not fitting the majority of common users. As the weed movement gains traction and becomes more mainstream worldwide, being used by people from all levels of society, its related product designs need a new expression: more discreet, minimal and contemporary. The global cannabis market is thought to be worth 150 billion USD today. Barclays, in one report of 2018, suggested that this figure could increase to 272 billion by 2028, matching the expected values of China's outbound tourism. These figures represent the scale of the industry but also suggest the continuation of its blossom. As a result, more designers are entering the scene, with new takes on objects, devices and different approaches to marijuana consumption. Here is our pick on 5 minimal, hand-made smoking pipes.
