Indiana considers not only well-known drugs like marijuana, heroin, and cocaine to be controlled substances, but also the compounds used to manufacture them. Some CDS, like codeine, may be legally possessed with a valid prescription.
A controlled substance is defined in Code of Virginia Â§ 54.1-3401, as a drug or substance listed in Schedules I through VI of the Virginia Drug Control Act. Alcohol and tobacco are excluded from this definition of a controlled substance; laws governing alcohol and tobacco are included elsewhere in the Code.
