On the topic of a Big Brother, I personally think that everyone should be fingerprinted at birth.
I don't have a clear opinion on legalization since I have never had any but I can tell you that if it's legalized, people will start smoking 2 packs a day (or at least more than before, again I haven't had any so I don't know if you would ever want to).
However, if legalized, the content of them would be regulated to make them less harmful or addictive I guess (I've heard some people say it's not addictive and some that it is but I guess I can only trust a scientist on that one).
well... if you'd make alcohol and smoking illegal everyone would probably start smoking marijuana... BUT if we made drugs legal there would be WAY more crimes and deaths than it is now because you can get very aggressive (My brothers friend is smokin marijuana) so pretty random someone could just kill you or start kicking your ass.
