You won't have to traverse dark alley ways to buy impure product trafficked from far away lands. Instead you will sit in your basement bio lab with elemental components and code together the necessary little functionality that you wish to have your host of living beasties produce for you. From heroine to vanilla, oil to alcohol.... when every one can bio synthesize what ever they want from scratch ...what need for outside suppliers?
Drug dealing will go extinct and in it's
place will spring up a wide industry where templates for production of all kinds of inebriating or mind dulling agents will emerge....the same way maker 3D files are shared online for use in 3D printers...or modeling files are shared for rendering CGI.
As people will be able to clandestinely supply their own drugs the risk of trying to buy them illegally doesn't have to be take…
