Do you happen to have a computer in your room? Because I know that on most computers you can take off a panal and just hide it in there. Hmm.. let's see.. I have a wooden box with a key on it, and I just put my shit in there. I told my parents that my porn was in there, and that they shouldn't go in there. They believed me, so it works well. Also, you can just put it in a pair of clothes that you don't use (in the winter put it in your shorts pocket, in summer put it in a jacket or something). Hmm... what else.. If it's a sorta small amount you can hide it nearly everywhere.. I used to put it in this metal mint box, and it really didn't look weird at all when I was carrying it around.. if you smoke cigs you can put it in there, my all-time favorite place, however, is I have a futon with a big sheet over it that acts as a cushion cover. You can sort of untuck the sheet and you basically have this little pocket thing that you can fit whatever you want in there. I can fit my bong, pipe, weed, lighter, scissors, tape, glue, etc all in the same place. Works great. You really can't even tell, honest.

Hope that helps, man. Happy smoking.
