A: I am not sure what you are asking. If you are charged with driving a vehicle under the influence of TCH (marijuana) then the level does not matter. However if you are charged with possession of marijuana, the amount becomes very important. If it is 30 grams or less, the charge is a misdemeanor. anything greater is a felony.
A: The answer depends on the charge. Under Indiana law, generally the state has 5 years for B, C, and D felonies and 2 years for misdemeanors. There are a few deviations for certain situations. These can be found in Indiana Code 35-41-4-2.
