Be informed about marijuana laws and CU’s Student Code of Conduct (PDF).
- Marijuana possession and use is only legal in Colorado for adults 21 and over. Underage use is subject to an MIP ticket, fines and CU sanctions.
- It is illegal for anyone (regardless of age) to have or use marijuana on campus in any form, even with a prescription.
- Being under the influence of marijuana is a violation of the CU drug policy and may result in student conduct sanctions and processes.
- Driving high could land you with a DUI. According to medical experts, it's best to wait before getting behind the wheel: at least six hours after smoking and eight hours after ingesting edibles.
- It’s illegal to take marijuana products out of the state. Additionally, Denver International Airport has banned the possession of marijuana products on its property.
- Using marijuana in any form (smoking, eating or vaping) isn’t allowed in public places, including ski resorts, sporting and music venues, state and national parks, campsites, sidewalks, restaurants and outdoor or rooftop cafes.
If you choose to use
Marijuana and its active components (THC and CBD) exist in many forms and strengths and can affect people in different ways. Whether it's your first time or you're a frequent user, here are some things to consider:
#1 Know the serving size, especially for edible marijuana products
Double check the serving size for edible marijuana products. A single serving should contain no more than 10 mg of THC. Remember, it may take 2 hours for edibles to begin to take effect and up to 4 hours to feel the full effect.
#2 Avoid mixing marijuana with alcohol and other controlled substances
Two or more substances used together can slow breathing and result in adverse side effects. Play it safe by using one substance at a time.
#3 Wait before engaging in activities that may put you at a higher risk
It’s recommended to wait at least 3-5 hours after vaping or smoking and 6-8 hours after consuming edibles before engaging in higher risk activities like driving, skiing or swimming.
#4 Start low and go slow
If you’ve never used marijuana before, start low and go slow until you know how it will affect you. This is especially important when experimenting with edibles and concentrates. Look for products with lower THC levels and wait to see how it affects you before consuming more.
For reference, flower usually contains 10-30% THC while concentrates commonly contain 60-90% or more. If you choose to use, go with products that are within your limits, and always follow the guidelines and directions provided on the original packaging.
#5 Reduce your frequency
Using marijuana less frequently has been shown to lower the risk of dependency, negative mental health symptoms and long-term health effects. Current recommendations suggest consuming marijuana no more than 1-2 times per week.
#6 Store marijuana products safely and keep them away from pets
Keep marijuana products in the original packaging so they are easily identifiable. Be sure to store them in a safe area that cannot be accessed by pets. Marijuana can be harmful to animals. If your pet does consume any marijuana products, call a vet right away.
Campus Resources
If you'd like to talk to someone, resources are available on campus. CU Health Promotion offers an Exploring Substance Use Workshop. This free, voluntary workshop provides students with a safe, non-judgmental space where they can explore their relationship with substance use and discuss personal experiences. Students of all levels of use and non-use are welcome.
