Oh, stop being so bloody male about it, with your indica this, and your sativa that, like you knew what the fuck any of it even meant. It's just weed, and it either gets you stoned or it doesn't. The mechanism is still not fully understood, but the latest hypothesis among advanced cannabologists is that a good blast on the Amy Wong inhibits the action of a natural hormone responsible for making you give a fuck.
The fact that you are getting paranoid suggests to me that the weed is working after a fashion, but your Set and Setting are all wrong. Smoking weed should chill you out and make you hungry, not paranoid. Revisit your Set and Setting, and try to find out -- and if possible, eliminate -- what is setting off the paranoia.
