Harvard Health Publishing reports that pain management is the most common use for medical marijuana in the United States. While marijuana may be less addicting than opiate medications, this drug may affect memory, learning, and understanding. Marijuana may also affect your blood pressure and contribute to respiratory problems. The Mayo Clinic lists several side effects of marijuana use, including headache, dizziness, drowsiness, paranoia, a feeling of disconnectedness, and coughing.
Oxycodone is a narcotic pain medication that is effective against moderate to severe pain. You can find oxycodone in prescription medications such as OxyContin, Percodan, and Percocet. While highly effective for treating pain, this opioid analgesic is also highly addictive. According to The Addiction Center, one of the highest risks of oxycodone use and abuse is the risk of an accidental, fatal overdose. Other side effects include nausea, vomiting, dizziness, drowsiness, and lightheadedness.
Hydrocodone, found in prescription medications such as Lortab and Vicodin, is another opioid pain medication used for severe pain. This medication is also a habit-forming drug that carries the risk of addiction. The depressant effects of this narcotic may interfere with breathing. Other possible side effects include drowsiness, headache, stomach pain, swollen ankles, and shaking.Related: 11 Medications That Cause Memory Loss
