Posting this is pouring salt onto a papercut already soaked in lemon juice, but the friend I lost over posting this on MyFaceGoogleTwitterBookPlusSpace (as a comment in another friend's post about an NPR (National Public Radio) [2] report on the “War on Police [3]”) probably won't listen to me any more and I feel this is actually important. It's not like I want all drugs to be illegal (quite the opposite in fact, I want them to all be legal, and tax the crap out of it) nor do I like the resulting “War on Drugs [4]” (Prohibi tion [5] ultimately failed, giving rise to organized crime) but drugs do have side effects, and for marijuana [6], paranoia [7] appears to be a valid side effect.
