Marijuana and its active components, THC and CBD, exist in many forms and strengths and can affect people differently.

Know the laws

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.

Consider these questions:

Do you know your limits?

If you plan to use, consider when you’ll be using, where you’ll be and who you’ll be with. The effects of marijuana can differ for each person and depend on how it’s used or consumed.

If using edibles, follow the serving size and give your body up to two hours to react before using more. This can help reduce the likelihood of experiencing a bad high.

How does marijuana affect your health?

According to research from the U.S. Department of Health and Human Services, smoking marijuana can increase an individual’s risk of lung and heart disease in the same way as smoking cigarettes. This research also shows, regardless of how it’s used, marijuana can significantly impact brain health.

The short-term effects of marijuana use include attention deficit and decreased memory and learning. Long-term effects include potentially permanent decreased learning and synapse formation and an increased risk of certain mental health disorders, according to studies published by the Proceedings of the National Academy of Sciences and the Schizophrenia Bulletin.

How will you know if your marijuana use is a problem?

People may not realize how their use may be affecting them. There are all sorts of ways this can happen—missing deadlines, dealing with a chronic cough, memory problems or facing failed attempts to cut down or stop using.
