Life got you down?  Feeling a little depressed about it?  Enough so that you chill with some of Washington's legal marijuana?  Maybe that's the problem!

The study show most people experience a psychological phenomenon called “fading effect bias.”  That basically means people prefer to hold onto positive feelings longer than negative ones.  Duh!

Some new preliminary research suggests heavy marijuana users might hold onto negative memories longer than others, which is also a trait shared by those suffering from -- depression.

In this study, as reported by LiveScience, researchers analyzed one group of people who didn’t use marijuana and a comparable group of heavy marijuana users – defined as those who use marijuana at least four times a week. The heavy marijuana users held onto unpleasant memories longer and recalled happy moments in more general terms than specific ones.

These new findings agree with previous research indicating a link between heavy marijuana use and depression.
