First time 2cb insanely powerful

we had a weight that could only register 0.1 and so we split that into 4 parts eye measure

It kicked in after 1 hour then i smoked some and was beginning to really trip after 2 hours thats when everything was changing colors in a wave like motion and everything was kind of acid like also 1 thing i thought was really weird was how sizes and perspectives was really weird i felt like a giant walking past houses and garbage cans while inside i looked at my legs and was a dwarf, our friend looked like he was 140cm

​

is it normal to experience a way more visual trip than 200 ug of acid?
