I agree with your sentiment as far as marijuana is concerned (and really all drugs), but the "it's just a plant" argument isn't solid in general. For example, if the police had evidence of a surreptitious castor bean grow room, and evidence of something being chemically extracted from the plant material, I think that may be enough to justify a search warrant to determine what's going on. Of course that evidence would have to come from someone capable of telling the difference between castor beans, tea leaves, their ass, and their elbow.
