very easy!
there has been NONE... ZERO ... NADA ... not one documented instance of pot directly causing a death.
you would think out the the billions of users in the history of pot use... if Pot was dangerous ... ONE document instance would show up.
don't get me wrong ... Pot is dope and will get you high .. why do you think they call it dope? but the worst documented side effect so far is the munchies.
by the way not a pot user... it's a documented fact pot users will quit on their own about age 35.
I have some ocean front property in AZ if you are interested.
