Colorado Drug Possession Laws

Created by FindLaw's team of attorney writers and editors.

Many states, in an effort to relieve overcrowding in prisons, have loosened the penalties for non-violent drug offenders. But while Colorado has legalized the possession and recreational use of marijuana (within certain limits), the possession of most controlled substances remains a felony in the state. And while the federal Drug Enforcement Agency (DEA) has allowed state legalization efforts to proceed unabated, marijuana possession is still technically illegal under federal law. But even the smallest amount of heroin or methamphetamine, for example, can land you in jail for up to 18 months.

Colorado's Controlled Substance Classifications

Each state classifies controlled substances (including both illicit drugs and those restricted to prescription use) are organized into "schedules" for purposes of crime classifications and penalties.

  • Schedule I: heroin, LSD
  • Schedule II: opium, codeine, methamphetamine
  • Schedule III: hydrocodone, anabolic steroids, ketamine
  • Schedule IV: lorazepam
