There are so many cannabis strains that it is difficult to choose just a few from hundreds of them. With “strongest cannabis strains” we mean cannabis strains that are very psychoactive, i.e. cannabis strains very rich in THC.

There are many factors that contribute to the strength of a cannabis strain both internal (genetics) and external (environmental) factors.
