Cannabis can affect attention, memory, coordination, reaction time, mood, and perception. Effects vary based on the amount used, THC concentration, method of use, individual factors, and whether cannabis is combined with alcohol or other drugs. This page provides UO policy information, health considerations, and support resources.
Cannabis use and possession are prohibited on University of Oregon property and at UO-sponsored activities, even when Oregon law would otherwise allow cannabis use or possession. This includes cannabis in forms such as smoking, vaping, and edibles. Review the UO Student Conduct Code for current policy language.
Oregon cannabis laws can change. For current information about legal age, possession limits, public use, home growing, transportation, and other requirements, visit the Oregon Health Authority and Oregon Liquor and Cannabis Commission.
Frequently Asked Questions
What are the effects of cannabis?
Cannabis can affect people differently. Possible effects include relaxation or euphoria, changes in perception, impaired attention and memory, slower reaction time, reduced coordination, anxiety, increased heart rate, and changes in appetite or sleep. Effects depend on the product, dose, method of use, individual factors, and whether other substances are used at the same time.
Can people become addicted to cannabis?
Some people develop cannabis use disorder, which can include difficulty cutting down, cravings, tolerance, or continuing to use despite problems at school, work, in relationships, or with health. If you are concerned about your use, a screening tool, counselor, or health care provider can help you think through next steps.
What if someone wants to stop using cannabis?
If you want to reduce or stop cannabis use, support is available. You can start with the anonymous CUDIT screening tool, schedule an initial consultation with the CRC, or connect with Counseling Services. You do not need to wait until your use feels severe to ask for support.
