I figured out a way to lessen global warming and reduce marijuana addicts over the long run?

The idea is to plant marijuana plants everywhere. Tons of it. The reason cannabis one of the best plants to plant to reduce global warming is because it grows really, really fast and absorbs a load of carbon dioxide for a plant. It also gives out Oxygen generously.
The reason it will actually (counterintuitively) reduce marijuana addiction is because the countries that made it legal saw a decrease in use, and this is because it's not seen as a symbol of rebellion anymore. And if we plant it everywhere people won't be as inclined to do year around flowering, which mean manijuanics could just smoke it on special yearly buddings.
Thoughts?
