I think that for any sort of drug in the server the charge for the drug should increase with the amount you have rather then just 1 charge. For example you would get a 5k charge for having 100 Meth and a 5k ticket for having 1 Meth. The price should increase depending on how much they have on them when you add a drug charge you add how much of the drug they had and it would automatically give an amount according to the amount of drugs.
