honestly, only you can answer this question. as with any drug, it affects diffrent people, diffrently.... for me, happiness... i guess maybe you could say at points i get down when i don't have it.. but i'm a manic depressive... i'm down alot... weed just helps open my eyes to the beauty around me, and appreciate it more... therefore i get out of being 'down' but don't take that the wrong way, i do not use it to hide my problems, or use it for anything like that... if you use drugs to 'hide' your problems, or yourself from the problems, it only compounds them and makes them worse.
