The federal government and states have laws against the use, manufacturing and distribution of drugs. Drugs statutes classify controlled substances according to schedules. Punishment for drug crimes depends on the quantity of the drug, its classification under the schedules and the purpose of the possession. The most serious drug crimes include producing illegal drugs, manufacturing or selling drugs and possession of drugs with the intent to distribute. Enhanced penalties go into effect if minors are used to distribute drugs or if drugs are sold to minors or on school property. Consequence of drug crimes can include prison time and hefty fines.
