WA Prosecutor lying/ misleading statements

[Spaceman]

In relation to cannabis possession can a prosecutor lie/ mislead the jury and court by saying wet cannabis was completely dry

 

[Iamthelaw]

No, they can't lie.

I can prove he did lie or at the very least made untruthful statements thereby presenting to the the jury an amount of usable cannabis up to 4 times more than there was what do you think my options are
