Effects of Cannabis on the Developing Brain

What is cannabis?


The usage of cannabis has peaked after legalization in California in late 2016. Cannabis or Marijuana is known as “weed” and according to the World Health Organization (WHO), is commonly used by adolescents for socialization and some young teens may think it “relaxes” their anxiety and depression. In reality, it can worsen anxiety and also negatively alter the brain. Cannabis may come in the form of gummies, baked goods, joints for smoke inhalation, chocolates, etc.


What are side effects of cannabis?
Common toxic effects of cannabis include sleepiness, behavioral changes, red eyes (conjunctival injection), irritability, tachycardia, persistent nausea/vomiting, and respiratory depression. In addition, if a child already has a respiratory condition like asthma, cannabis can trigger their symptoms and potentially cause asthma exacerbations.


What are some long term effects of cannabis?


While cannabis may initially “relax” symptoms of anxiety, it can actually produce a rebound effect and worsen anxiety with long-term use. Neuroimaging studies show that cannabis will physically alter the brain’s chemistry which can lead to decreased cognitive function, attention, memory, concentration, and dependence with higher-tolerances. Additionally, cannabis use disorder may lead to both liver and kidney damage. These lasting neurological effects can negatively influence how your child’s brain develops.
