Drug trial
He is to be tried for the drugs thing, the murder thing is (at this stage) only an allegation (heresay) and should have no part in this trial.
His views on drugs, murder, commerce or anything else is also nothing to do with the drugs charges unless he decides to use religious exemption (I is Rastafari) or plead guilty and wants his views taken into consideration in mitigation ( 'please be lenient on my client, he was a misguided fool but has seen the error of his ways' )
The murder thing has nothing to do with his guilt/innocence of the drugs thing and should also be kept separate.
Likewise the other thing (whatever that may be, tax evasion probably)
Biting the hand that feeds IT
