Fer my drugs, I keep them in a lockbox so's no-one can look-see. Actually I use it so if ever the law come's by they gotta get a warant to open it.
Actually, in the States, the cops need a warrant to search ANYWHERE in your house... UNLESS:
(1) you give them permission, or
(2) there are "exigent circumstances", meaning that the cops would have to testify that there was some kind of emergeny going on inside that would have made it unreasonable for them to have to go get a warrant (like they can hear someone inside screaming for help or they have a reason to believe that evidence is being destroyed inside)
