There first has to be some actual evidence that you were buying drugs online. If the cops search you and find drugs, it isn't going to matter a lot one way or the other whether you have Tor installed.
If you weren't actually buying drugs online then there shouldn't be any evidence that you were (or the cops planted it and then we're back to it not really mattering whether you have Tor installed). And then what are they charging you with that would even make it to a jury instead of being dismissed by the judge for lack of evidence?
