The dealer, budtender, or a kid in highschool can tell you smoking Shatter or concentrates much higher in THC will cause more anxiety, that's the whole thing about THC.

How about me and my friends/family 15 year study between the 30+ of us who can all tell you the exact same thing.

This is like saying "Caffeine and Milk in equal quantities will have less of an effect than just a whole cup of coffee."
