Legal Marijuana Colorado and the Law

Understanding Colorado Marijuana Laws


Key Points of Amendment 64

Amendment 64 removes criminal penalties for adults who wish to use, display or sell marijuana. Recreational legal marijuana is now available for any adult to purchase at our Downtown Denver dispensary or our Boulder recreational dispensary.

 The first $40 million of annual revenue raised by the tax of legal marijuana will go to the Public School Capital Construction Assistance Fund.

 The State of Colorado must provide for licensing and regulations of legal marijuana retail stores and cultivation, testing and manufacturing facilities for legal marijuana and industrial hemp.

Legal marijuana and legal marijuana-infused products sold in the State of Colorado must be clearly labeled.
Industrial hemp (cannabis plants with less than 3% THC concentration) will have different regulation policies than recreational cannabis with higher levels of THC.

Local governments are responsible for regulating and/or prohibiting legal marijuana facilities in their towns.

Key Points of Amendment 20


On November 7, 2000, Amendment 20 was passed by 54% of Colorado residents, who voted to change existing marijuana laws to allow for medical marijuana in Denver and statewide.

This constitutional amendment is only for the State of Colorado's Constitution, not for that of the United States. This amendment excepts patients, caregivers and physicians from criminal prosecution for the use, distribution and prescription of medical marijuana in Colorado.

In order to become a medical marijuana patient and to purchase from a legal marijuana dispensary, the individual must be a patient.

A “patient” is defined as a person who has a debilitating medical condition and has a Red Card. For a list of accepted conditions to obtain a Red Card Colorado, please see our How To Apply Guide.

Amendment 20 makes medical marijuana use by qualified patients a constitutional right for Colorado residents over the age of 18.

Patients under the age of 18 must have recommendations from two physicians to be considered for medical marijuana use.

  • Patients can purchase and posses up to two ounces of medical marijuana with a state registered Red Card and government-issued ID.


  • Patients can purchase edibles, marijuana concentrates and medical marijuana flowers that have high potencies of THC and CBD.


  • Patients can use medical marijuana however they please in the privacy of their own homes, so long as it is not endangering others.
  • Patients are allowed no more than two ounces of medical marijuana in their possession at one time.


  • Patients can specify a caregiver or grow no more than six plants, with three or fewer mature flowering medical marijuana plants and three vegetative plants.


  • Under Colorado marijuana laws, patients may not use medical marijuana in public places or in plain view of the public.


  • Under Colorado marijuana laws, patients may not use medical marijuana in a way that endangers the health or well being of any person. This includes driving under the influence of marijuana.


  • Under Colorado marijuana laws, patients may not redistribute any medical marijuana products.
