Cannabis sativa does grow wild. It's become one of the most widespread and diversified of plants. It grows as weed all over the world in a variety of climates and soils.
One 'feral' strain is Cannabis ruderalis 'Janisch'. The term "ruderal" was originally used in the former Soviet Union to describe populations of hemp that had escaped cultivation and adapted to the surrounding region. Plants of this type are widespread throughout central and eastern Europe, including Lithuania, Belarus, Latvia, and Estonia. Similar populations can be found in most of the areas where hemp cultivation was once prevalent. The most notable region in North America is the midwest, though populations occur sporadically throughout the United States and Canada. These plants have escaped from cultivation more recently, and often grow larger than the ruderal plants in Europe.
Cannabis users often call this feral Cannabis "ditch weed." Outside of its native range, it is regarded as an invasive plant. Despite years of government-sponsored eradication programs, these feral plants still remain in bountiful abundance.
Also, last year I was on hoilday in Nepal where it was growing wild all over the place.
