- Sidewalks.
- Parks and amusement parks.
- Ski resorts.
- Concert venues.

- Restaurants, cafes or bars.

Use on federal land is illegal:
- Since marijuana is still illegal under federal law, you can’t use on federal land, including national parks and national forests. This includes ski slopes.
Where you CAN use:
- Private property is your best bet. However, property owners can ban the use and possession of marijuana on their properties. If you rent, you may not be allowed to use marijuana in your home.
- Hotel owners can ban the use and possession of marijuana on their properties, so you may not be able to use in a hotel room. Be sure to research the places you’ll be staying in Colorado.
Drug testing at work:
- Despite legalization, employers can still test for marijuana and make employment decisions based on drug test results. Be sure you know your workplace policies before you use.

- Packaging requirements:
- Retail and medical marijuana businesses are required to sell all marijuana products in packaging that’s resealable, child-resistant and not see-through. The packaging protects children, teens and adults from accidentally eating something that they don’t realize contains marijuana. Using the packaging from the store is an important first step in safe storage.
- Labeling requirements:
- The Department of Revenue requires that all retail marijuana products use the symbol pictured here on packaging. Teach your kids not to eat or drink anything with this symbol on the package. Also, adults who can’t read the ingredient label can use this symbol as a warning that the product contains marijuana.
Pregnant people
- Marijuana use during pregnancy is unsafe and may have legal consequences.
- Some hospitals test babies after birth for drugs. If your baby tests positive for THC at birth, hospitals may choose to notify child protective services.

Impairment
- For occasional consumers, using 10 mg or more of THC is likely to cause impairment. This impacts your ability to drive, bike or perform other safety-sensitive activities.
- People may think that they’re “safer” drivers while stoned. However, research shows that driving while high may increase your risk of a crash since your reaction time is slower and your understanding of distance and speed is different. If you’re high, you shouldn’t drive, bike or operate machinery.
- Smoking:
- Wait at least six hours after smoking up to 35 mg of THC before driving or biking. If you’ve smoked more than 35 mg, wait longer.
- Eating or drinking:
- Wait at least eight hours after eating or drinking up to 18 mg of THC before driving or biking. If you’ve consumed more than 18 mg, wait longer.
- Marijuana affects individuals differently.
- These times are estimates based on research findings. If you’re unsure how marijuana will affect you, make other plans for transportation or don’t drive.
- Multiple substances:
- Using alcohol and marijuana at the same time is likely to result in greater impairment than either one alone.
Be careful where you travel
- Keep it in Colorado.
- Leaving the state with any marijuana product is against the law.
- You can’t bring marijuana to Denver International Airport or any other airport.
- Not in federal parks or on federal land:
- Since marijuana is still illegal under federal law, you can’t use it on federal land, including national parks and national forests. This includes ski slopes.
Driving and Travelling
- Driving while impaired is illegal and unsafe
- Getting high before you drive can get you arrested for a driving under the influence (DUI) charge. This is true even though marijuana use is legal for adults in Colorado.
- Similar to alcohol, there’s an established impairment level for marijuana in Colorado.
- By law, drivers with 5 nanograms of delta-9 tetrahydrocannabinol (THC) per milliliter of whole blood can be prosecuted for DUI.
- Even if marijuana is used medically, officers can arrest you for impaired driving.
- No open containers:
- Neither drivers nor passengers are allowed to open any marijuana packaging and use the product while in a vehicle, even if you are not moving.
- You can be charged with a traffic offense if the marijuana product seal has been broken, some of the product has been consumed and there’s evidence that it was used in the car.

Tax Rate
- Retail marijuana is subject to a 15 percent sales tax, levied on retail sales, and a 15 percent excise tax, levied on the first transfer of marijuana from a wholesaler to a processor or retailer.
- Adult-use retail: Sales are subject to a 15% cannabis excise tax and any additional local taxes.
- Medical marijuana: Sales are subject to a 2.9% state excise tax and any additional local taxes.
- Wholesalers are additionally subject to a 15% excise tax, levied on the first transfer of marijuana to a processor or retailer.
Tax Exemptions
- Medical marijuana is exempt from the 15 percent sales tax and 15 percent excise tax.
- Marijuana taxes
- A 15% retail sales tax at point of sale and a 15 percent excise tax was added to the wholesale price of retail marijuana (between cultivators and businesses).
- These taxes don’t apply to medical marijuana.
Distribution
- Via the Old Age Pension Fund, marijuana tax revenue is allocated to the General Fund.2 From the General Fund, revenue from the marijuana retail sales tax and excise tax are distributed differently.
- Ten percent of the revenue from the 15 percent tax on marijuana retail sales is allocated to local governments and apportioned according to the percentage of marijuana retail sales occurring within city and county boundaries. The remaining 90 percent is allocated as follows:
- 71.85% to the Marijuana Tax Cash Fund;
- 15.56% to the General Fund; and
- 12.59% to the State Public School Fund.
- Revenue in the Marijuana Tax Cash Fund is required to be spent the year after it is collected and used for health care, health education, substance abuse prevention and treatment programs, and law enforcement.
- The marijuana excise tax revenue is credited to the Building Excellent Schools Today (BEST) Fund. The BEST Fund is used to renew or replace deteriorating public schools. BEST grants are awarded on a competitive basis annually and funding is prioritized based on issues such as asbestos removal, building code violations, overcrowding, and poor indoor air quality.
Advertising
- Cannabis companies are extremely limited in what language and images they can use in advertising. In order to continue attracting customers, businesses have to devise creative alternative marketing strategies to skirt these laws.
- Colorado’s cannabis advertising laws can create obstacles for cannabis businesses that hinder their ability to reach a target audience. Social media platforms also censor cannabis content, making it difficult for cannabis companies to have a wide reach online.
- A Colorado law stated that cannabis companies cannot advertise on television or radio without “reliable evidence that no more than 30% of the publication’s readership is reasonably expected to be under the age of 21.” This rule also applied to print and digital media.
- Cannabis advertising is censored by social media platforms like Instagram, Snapchat and TikTok. Once the Flower Power Botanicals account was flagged for cannabis on Instagram, the platform continued to keep a close eye on the account, Mitchell said. He also said he attempted to advertise on TikTok, but after putting some funding into it, he was denied and did not receive a refund.
- Cannabis businesses are also restricted in outdoor advertising, although Fort Collins did allow Flower Power Botanicals a simple billboard on Mulberry Street. Flower Power Botanicals also has two banners hanging at the intersection of Lemay Avenue and Duff Drive.
- Advertising agencies also need to keep up on the current advertising laws to ensure their clients are protected.
- These laws and restrictions have led cannabis companies to create marketing strategies that differ from noncannabis businesses. Dispensaries can sponsor community events as well as highways.
- The Sponsor a Highway program is popular with dispensaries and has proved an effective way to expand reach without getting in legal trouble. Dispensaries can sponsor a stretch of highway by paying for its maintenance and, in exchange, place their logo on the highway.
