someone told me if you scoop molly in the filter of a parliament its exactly a tenth of a gram, can someone back this up?
No, measuring chemicals based on the size of gel capsules or a cigarette filter in this case is a very unreliable method. Especially with something like molly which has various synthesis methods and can be adulterated creating different weights of the powder/crystals.
Agree, I had a snuff bullet that would measure out bumps, a bump of k would usually weigh 30mg, while the same bump of m1 would weigh about 50mg. That's like weighing water in a gallon jug and than putting oil in the gallon jug and expecting it to weigh the same. This is 7th grade science.
