Abortions IMO, will alway be legal. The reason for this thinking is because its "legalized population control." The reason why a political power (Demicrat/Republican) will have a different view in the public eye. Cannabis should be legal for the pros. I.E food, clothing, shelter, work, stress free, etc are associated with legalized cannabis. However it would be regulated extensively.
Lastly, as said in GTA5, terrorist acts raise the funding amount for anti-terrorist and military organizations. Wars make money.
