Cannabis in Colorado: Laws, Legalization and Regulation

After marijuana legalization in Colorado, it can be complicated for tourists visiting the state to abide by all the rules and weed laws. This guide spotlights the main regulations that individuals have to observe to get 100% legal cannabis experience. Read this helpful post with practical advice if you don’t want to get a ticket for possessing or consuming green in the wrong place.

Regarding its attitude towards marijuana, Colorado remains one of the most liberal states in the United States. It approved the use of medical cannabis in 2000 and legalized weed for recreational consumption in 2012. Along with Washington, Colorado was the first state in the nation that allowed the sale, use, and cultivation of cannabis for recreational purposes. In 2014, the commercial sale of pot started across the state providing the product to citizens of 21 years and older. It has become an important date for Colorado because this policy has led to hash tourism and brought the state significant profits. Now, delivery services and retail locations offer a vast array of hemp-infused products for Colorado marijuana enthusiasts: flowers, edibles, topicals, concentrates, oils, cannabis seeds, and multiple innovative goods. The citizens with medical needs who are registered with the state can possess up to 2 oz. (57 grams) of hemp. For recreational use, legal aged adults are allowed to possess 1 ounce of weed or 8 grams of concentrates. Out-of-state visitors are also permitted to have this amount of marijuana. They can legally have 1 oz. of Colorado weed while traveling within the state and give away as a gift to other citizens of 21 and older. The possession of hemp paraphernalia is prohibited and punishable by a fine of $100.

Buying Marijuana in Colorado?

About 175 out of 272 municipalities in Colorado allowed the sale of recreational hemp after it had become legal. Use cannabis shops menu to find the nearest licensed retailer because not all dispensaries offer recreational marijuana for sale. With the first Proposition passed in the state, individuals were limited to buying only 7 grams of weed a day in retail stores. In 2016, the law was changed, and now it allows adults of 21 to purchase 1 oz./28 grams of flowers per day. Concentrates and edibles are determined as non-equivalent products with a different THC level and treated differently when you make a purchase. According to new standards, 28 g of flowers = 8 g of concentrates = 800 mg of edibles. These equivalency guidelines have become a grey area because buying a combination of weed products (like concentrates plus flowers), it is not easy to stay within legal limits. Colorado residents of 18-21 years old can buy weed for medical treatment with a valid doctor’s recommendation and an ID. Their purchase limit is 2 oz. As a rule, retail stores and dispensaries operate from 8 a.m. to 10/12 p.m., but each city can dictate its own rules within the assigned time frame, and the closing time can vary. The state doesn’t support reciprocity. In connection therewith, Colorado non-residents with an approved medical consent cannot buy weed from medical marijuana (MMJ) dispensaries and have to purchase it in stores as recreational customers.

Medical and recreational cannabis delivery services are allowed across the state, but cities have the right to permit or reject this decision. Most cities haven’t declared their position yet.

Cannabis consumption in Colorado

It is legal to buy and possess marijuana in Colorado, and this attracts a lot of tourists who are coming here to try the product. However, it is illegal to consume marijuana anywhere. To remain safe in the state, use the designated areas to consume weed.

You can smoke in:

  • your private house (or as agreed in your lease with a property owner);
  • your backyard out of the public view;
  • icensed cannabis consumption facilities;
  • otels that have declared as “smoker-friendly.”
  • he age to smoke weed is 21 and older.

Consumption of your own weed is not allowed:

  • on federal lands and federal properties (national forests/parks and courthouses) with a fine of $1,000 and a year of jail time on the first offense recording;
  • any public place (ski resorts, school campus, transport, restaurants, sidewalks), on public venues (concerts);
  • in a car;
  • at local parks, amusement parks;

on any premises where tobacco use is prohibited. A new bill passed in May 2019 allowed subsidiary businesses to apply for on-site cannabis consumption. The application process is difficult and long, but some firms that happened to succeed created special tasting rooms, private clubs, and bring-your-own-weed lounges to consume it. These marijuana-based hospitality establishments start opening their doors in Colorado. Some companies can test their employees for cannabis and make employment choices based on the results of the drug test. Check the workplace policy before applying for a job. If individuals under 21 are caught while consuming or possessing pot, they will not face a criminal citation but a civil penalty. Schools may have other disciplinary policies for students who are caught on school property. Some legal penalties may include fines or prison sentences.

Taxes on Marijuana in Colorado

With a Colorado medical marijuana card, you can save good money on cannabis purchases because when buying weed for medical use, you are not imposed to pay a retail sales tax (10%), a state retail excise tax (15%), and a local city marijuana tax. As a result, the final retail purchase price for recreational weed is quite hefty. Consumers should pay both retail sales weed taxes. A good point is that this cannabis is exempt from the 2.9% standard state sales tax. On the contrary, medicinal marijuana is only subject to the 2.9% state sales tax.

Colorado Medical Marijuana Card

In fact, to buy marijuana in stores, you don’t need to be registered in the MMJ program. However, qualified patients can enjoy reduced prices on cannabis products offered in dispensaries and avoid payments for weed taxation. The fee to renew your card yearly will surely pay for itself. In addition, medical patients can get legal access to higher amounts of cannabis (more than 2 oz.), if they have a recommendation from a physician. Colorado doesn’t honor medical cards issued out of state, and non-residents cannot use them making a purchase in a local dispensary.
