The State of Texas has developed its own drug classification system outside the Controlled Substances Act of 1970. Instead of schedules, it categorizes drugs into penalty groups.

While marijuana laws are changing, Texas still has some of the toughest laws in the U.S. when it comes to the possession and sale of cannabis. Even small amounts of the drug can land you in jail for several months and incur expensive fines. Although the Texas governor recently signed the state’s first medical marijuana bill, personal possession and sale are still illegal.
