A"Controlled substance" means a substance, including a drug, an adulterant, and a dilutant, listed in Schedules I through V or Penalty Groups 1, 1-A, or 2 through 4. The term includes the aggregate weight of any mixture, solution, or other substance containing a controlled substance.
The punishment for manufacture and delivery of controlled substances vary depending on the type of drug and the quantity involved in the offense. Texas drug laws (The Texas Penal Code and Texas health and safety code) divides the offenses and punishment in four penalty groups, by drug classification.
