In today’s world, marijuana use is becoming increasingly popular, with states such as Oregon and Colorado legalizing marijuana for recreational use. Many people have wondered what marijuana does to the brain. However, does the legalization of marijuana suggest that the drug is not as harmful as the public previously thought? What does the research show? How does marijuana really affect the brain? A few recent studies reveal some important facts about the dangers of marijuana.
General Effects on the Brain
For years studies have shown the devastating effects marijuana has on the brain, particularly on the orbitofrontal cortex of the brain, which is tied to addiction. Other studies have shown that those who smoke pot during their teenage years have lower IQs later in life. Another study, performed by geneticist Arpana Agrawal of Washington University in St. Louis, revealed that teens who smoke pot even once had a smaller amygdalla and ventral striatum, which are brain regions associated to emotion processing, reward seeking, and reward processing. Other effects include, impaired learning and coordination.
Psychosis
More and more research is pointing to marijuana use as a cause to psychotic symptoms such as schizophrenia and bizarre thoughts. Study participants between the ages of 12 and 18 in the UK each experienced symptoms of psychosis, which can be dangerous to ones self and others.
Motivation and Judgement
Backing up an already existing stereotype, recent research also shows that the brains of those that frequently smoke marijuana produce less chemicals related to motivation and initiative. These same users produced less dopamine, which is also related to reward-driven behavior.
While research is continually being performed on the effects of the drug, our doctors recommend avoiding anything that significantly alters brain activity or causes hallucinations. Almost any outside force used to create pleasure or reduce stress, other than eating right, sleeping well, and exercising is generally a bad idea.
