increased chance for lung cancer.

Editor's Notes
For this project, I would like to focus on marijuana use among college students. This will look at if marijuana use increased or decreased amongst college students during the pandemic, as well as the effects of use on their academic performance.
So in its most basic form…
Plant with psychoactive effects…
But those are the short-term effect
As much as I’d like to make a prezi advocating for marijuana and its benefits, let’s be real,
There are a lot risks and negative effects of marijuana use, just like any drug out there
So that will be my focus today…
