That folks who can't get high are suffering from an endocannabinoid deficiency. Endocannabinoids are body-produced chemicals that are needed for a lot of bodily functions. Without them, you are very sick! The theory goes that if you lack endocannabinoids, you can't get high because your body snatches them to make the endocannabinoids that you need. So none of it gets to your brain- no THC in the brain, no high! The solution is to smoke more and improve your diet! (Modern diet is just a slow way to die- chlolesterol, transfats, no fiber, vitamins processed out, no raw foods except a bit of watery iceberg lettuce, etc) You might find this to be an interesting article-- http://www.freedomtoexhale.com/clinical.pdf Russo is dealing with extreme cases, but the basic idea is interesting. The psychological side of things should be considered, too. If you feel uncomfortable for any reason, it cuts into the high. You got high with your friend, but not with your boyfriend. Think about it. That high was more like it's supposed to be. The flavor of pot varies as does the high. I like the heavy indicas (fat leaves, "heavy" painkilling high-I get migraines if I don't toke), but my hubby likes sativas (skinny leaves, an "up" party high- sometimes with paranoia). Your different effects may be due to a difference in varieties. Ask your friend if he knows what type he had. Your paranoia suggests that it was a sativa. Take care of yourself. Get a vaporizer.
