Kush is known to be a type of weed, but it comes from a particular breed, which is cannabis. This is considered to be medicinal by a lot of people. In fact, cannabis has always been considered to be very helpful to people who are suffering from different types of conditions.
There are some people who have conditions that are considered to be serious, but their symptoms can be reduced or even removed. Weeds, on the other hand, are considered to be plant growth that is not particularly helpful to anyone. Weeds are normally unwanted in your backyard, and you would like to remove them the moment that you get the chance.
