Back in the days when “skunk” was mainly associated with cartoon character Pepé Le Pew and hydroponics was a way of improving cucumbers, most of the United Kingdom’s cannabis supply was imported from places such as Morocco and Lebanon. This changed in the past two or three decades in the UK and many other countries as organised criminal gangs set up growing operations closer to home.

Cannabis was still cultivated and distributed out of the more exotic locations on a large scale, particularly when it came to resin, but a fair amount of production had now moved closer to the demand in a process economists call import substitution.
