Not every drug case in San Antonio ends up in the same courthouse. Depending on the quantity involved, whether the case crosses state lines, and which agency makes the arrest, a drug trafficking charge can be prosecuted under Texas state law or under federal law, and the difference between the two can mean the difference between years and decades.
Under the Texas Controlled Substances Act, drug charges are classified largely by the type and weight of the substance involved. What starts as a possession charge can become a manufacture or delivery charge, and eventually a trafficking-level charge, purely as the quantity increases. Texas state penalties scale with these categories, and while they can be severe, especially for larger quantities, they generally leave more room for judicial discretion than federal law does.
Federal drug trafficking charges typically involve larger quantities, distribution networks that cross state or international lines, or the involvement of a federal agency such as the DEA or FBI from the start. San Antonio's location along interstate drug corridors makes it a city where federal drug task forces are particularly active, and a case that might have stayed local in another part of the state can attract federal attention here because of that geography.
Federal drug trafficking offenses often come with mandatory minimum sentences that apply regardless of a defendant's individual circumstances, tied directly to drug type and quantity thresholds under federal law. Unlike Texas state sentencing, where a judge has meaningful discretion, a federal mandatory minimum removes that discretion almost entirely once the threshold is met. This is one of the sharpest differences between the two systems, and it is often the single biggest factor in how a case should be defended from the earliest stage.
Federal drug cases frequently involve conspiracy charges that can sweep in people whose direct involvement was limited, since federal conspiracy law allows the government to charge everyone connected to an operation, not just the person found with the drugs. This makes an early, careful evaluation of exactly what a person is alleged to have done critical, since the difference between being a central figure and a peripheral one can significantly affect both the charge and the available defenses.
Whether your case is being handled at the state or federal level, understanding which system you are in changes everything about how it should be defended. Jim Wheat's background spans both systems, giving him the ability to evaluate early whether a case is likely to remain in Bexar County state court or attract federal attention.
