Manitoba Poison Strain

A couple of decades ago, IBM released an ad stating how the world was getting smaller. The company then was referring to global connectivity as technology continues to advance. It is the same thing too with regards to the world of marijuana. From Africa, strains found their way to Canada. And, as a result, it gave birth to Manitoba Poison. For cannabis enthusiasts, the world today is one without borders.

The strain traces its lineage to pure African landrace varieties. While no one knows precisely which ones the breeder used, most do tend to be Sativa. Not all, though, as Manitoba Poison is a balanced hybrid. It appears then that there must have been an Indica plant used in its breeding. Whether this other parent strain is native to Africa or not, that is no longer a concern.

Credit goes to Great White North Seed Company for breeding Manitoba Poison. Since its release, it has become one of the pride of the region. It also proves once again that the best cannabis hybrids are not limited to Europe or USA.

Although it has equal sides, the Manitoba Poison does tend to have a more pronounced Sativa effects. It comes with some 14% to 16% THC, an amount that is potent but not likely to be overwhelming. Even as it provides excellent effects for recreational users, it also brings many benefits for medical cannabis users.
