Not really. The whole thing is, you smoke until you're high and some people have a paranoid or panic reaction to being high. In the 70s you smoked 3 joints or bowls to reach that point. Now you smoke half of one. But at some point you have reached all of the receptors in your brain and you don't really get "higher" or more prone to paranoia at that point.
The interesting thing is, the Sativa plant results in a buzzier and more paranoid high, and the Indica results in a more narcotic sort of high. So since California went legal, weed growers set out to produce plants that are more effective for different kinds of medical needs.

1. Relieves body pain
2. Relaxes muscles

You now know more than most smokers, who should at least understand that Indica is "couch-lock" weed and Sativa is "Let's write some songs" weed.
