Opioid-related deaths fell 6.5% in Colorado due to Marijuana legalization

A new study finds the legalization of cannabis in Colorado associated with significant reduction in opioid-related deaths. Another study shows that long-term use of marijuana changes the brain at a cellular level.

Researchers from Brigham Young University’s neuroscience department found long-term use of cannabis depressed gamma-aminobutyric acid (GABA) cell activity in the ventral tegmental area (VTA), they said  “necessary for reward behavior with dopamine cells critically involved in reward signaling.”

In their study, researchers injected adolescent mice with THC. The psychoactive component of marijuana, and found the drug triggers cellular-level changes in the VTA of teenage mice. Making them dependent on the drug.

After one week of daily injections, researchers found that THC affected the function of GABA neuron cells in the mice. Making it harder for them to reach the same high without the use of greater amounts of marijuana. Mice that only received one injection did not show the same changes. Leading researchers to conclude that persistent consumption of THC may affect the function of the brain over time.

“Marijuana use and legalization is a pressing issue for many states. Although marijuana is the most commonly abused illicit drug, the implications of legalized, widespread or continued usage are speculative,” one researcher wrote.

Twenty-nine states and the District of Columbia currently have laws legalizing marijuana in some form. California has legalized weed for recreational use, with markets set to open in January 2018.

The legalization of marijuana in Colorado has led to a 6 percent reduction in opioid-related deaths in the state. According to a new study published online last week in the American Journal of Public Health.

“After Colorado’s legalization of recreational cannabis sale and use. opioid-related deaths decreased more than 6 percent in the following two years,” said the team of investigators from the University Of North Texas School Of Public Health, the University of Florida, and Emory University concluded.

Opioid crisis

The authors of the study said the reductions in opioid-related deaths related to “a reversal of the upward trend in opioid-related deaths.” However, they stressed only the preliminary results. Given that they only studied data from the two years after recreational marijuana was legalized in 2014.

Using data from the Centers for Disease Control and Prevention’s (CDC) Wide-ranging Online Data for Epidemiologic Research (WONDER) to chart the number of opioid-related deaths each month from 2000 to 2015.

This is the first study to look at the correlation between recreational marijuana and opioid deaths. The study states that their research “extends” on prior studies “on the potential protective effect of medical cannabis legalization on opioid-related deaths.”

Researchers isolated the effects of legalized recreational cannabis by comparing data from Colorado and Nevada, since both states legalized medical marijuana in the same year, but Nevada did not legalize recreational weed use until 2017.

Opioids killed more than 33,000 people in 2015, according to the CDC. Half of those deaths involved a prescription opioid.

The CDC does not include any statistics for marijuana-related deaths. However, it states that cannabis use can lead to addiction. Adversely affect brain health, lung health, heart health and mental health.

Reasons Behind growth of Alternative Medicine

The researchers warned that they found health benefits from reducing the number of opioid-related deaths, they noted that “expanded legalized cannabis use is also associated with significant potential harms.”
