Detailed Information

Recreational Cannabis Laws

In Colorado, recreational cannabis was legalized on January 1, 2014, following the passage of Amendment 64 in November 2012. This law allows adults aged 21 and over to legally possess, use, and purchase cannabis for recreational purposes. The legislation permits the sale of cannabis products through licensed retail dispensaries, which must comply with state regulations regarding cultivation, distribution, and sales.

Purchase Limits

Adults can purchase up to 1 ounce (28 grams) of cannabis flower per transaction. Additionally, they can buy up to 8 grams of concentrated cannabis (such as oils or waxes) and up to 800 milligrams of edibles (which typically contain 10 milligrams of THC per serving). These limits are enforced to ensure responsible consumption and to prevent over-purchasing.

Possession Limits

Individuals are allowed to possess up to 1 ounce of cannabis in public. At home, adults can store up to 8 ounces (approximately 226 grams) of cannabis flower. It is important to note that possession limits apply to both recreational and medical cannabis, but medical patients may have higher possession limits under their specific guidelines.

Home Growing

Colorado residents aged 21 and older are permitted to grow cannabis at home. Each individual can cultivate up to 6 plants, with a maximum of 12 plants allowed per household, regardless of the number of adults living there. The plants must be grown in a secure location that is not visible to the public. There are no specific restrictions on whether the plants are grown indoors or outdoors, but outdoor growing must comply with local zoning laws.

Where to Buy

Colorado has a robust market for cannabis, with approximately 1,000 licensed retail dispensaries operating throughout the state. Consumers can find dispensaries through online directories or by visiting local cannabis shops. Dispensaries must obtain a state license and comply with strict regulations regarding product safety, labeling, and advertising. Many dispensaries also offer educational resources to help consumers make informed choices.

Public Consumption

Public consumption of cannabis is generally prohibited in Colorado. This includes consumption in public parks, on sidewalks, and in most outdoor spaces. Some private establishments, such as cannabis clubs or certain hotels, may allow consumption on their premises, but this varies by location. Violating public consumption laws can result in fines, typically ranging from $15 to $100, depending on the circumstances.

Driving Laws

Driving under the influence of cannabis is illegal in Colorado. The legal limit for THC in the bloodstream while driving is 5 nanograms per milliliter (ng/mL). Penalties for DUI can include fines, license suspension, and even jail time, depending on the severity of the offense and whether it is a repeat violation. Additionally, open container laws apply, meaning that cannabis products must be stored in a sealed container while in a vehicle.

Important Restrictions

  • Federal law implications: Cannabis remains illegal under federal law, which can create complications for users, especially regarding employment and banking.
  • Crossing state/country borders: It is illegal to transport cannabis across state lines, even if traveling to a state where cannabis is legal. Additionally, crossing international borders with cannabis is strictly prohibited.
  • Workplace drug testing: Employers in Colorado retain the right to enforce drug-free workplace policies, which may include drug testing for cannabis use.
  • Landlord restrictions: Landlords can prohibit cannabis use and possession in rental properties, even if it is legal under state law.
