Branding
In an economic world, brand is everything. In the cannabis space, it is much harder than other industries as we have such restrictions on our paid social media marketing. With the growth of social platforms, brands can be built nearly overnight with a paid-marketing budget and a good product. This is not available to the cannabis industry as of yet.
Everyone makes sure to have shirts, hats etc, why not branded pipes? A T-shirt has to be washed after it's been worn one day, there is also still a stigma around cannabis which can cause that shirt to not be worn in public. Having a branded pipe in your customers hands is as targeted of marketing as you can get. When your customer has friends over, your brand will be the center of attention.
