Meanwhile, things are moving fast in Colorado thanks to several doctors’ testimonies last yeast about the increasing cases of psychotic episodes linked to cannabis concentrate. To address the situation, a bill was unanimously passed to curb access to high-potency cannabis concentrates.

A section of the legislation also charged the medical school at Colorado University to carry out a full review of over 800 scientific articles. The articles are said to cover the effects of high-potency cannabis concentrated on both mental and physical health. The report is said to be due come July.

Heading the team is Dr. Jon Samet who is also in charge of the project. In his words, he affirmed the study won’t be an easy one given there is a lot of messy data to organize from the studies whose authors used different methods of measurement. However, he shared his anticipation of creating the latest public research database for the state.

In the state of Washington, researchers are a step further after completing a six-month review executed by 11 scientists in 2020. The research revealed that THC has a dose-response. This implies that the more THC one consumes, the higher the negative impact on mental and physical health. This research kicked off immediately after sales of THC concentrate increased from 9% to 35% between 2014 to 2020.

The researchers also revealed that young adults were most vulnerable to the side effects and getting addicted to high THC concentrations. They then concluded that there’s a need for more police declarations and considerations to support public well-being and general health.

Carlini, who led the Washington researchers, affirmed that other states looking for guidance have also reached out to her. She added that the initial mistakes are glaring for all to see and people are ready to learn from their mistakes. Researchers from both states are now keeping in touch and consulting each other when necessary

Regarding Seattle, researchers are looking for new ways to curb access to THC concentrate. Approaches under evaluation include tax established on potency level or cap on potency which is the approcahbuded in New York and Illinois.


The research team in Washington is considering warning labels like those employed in Canada. The warning label will explicitly state the risks of high THC levels to mental health. The Washington research team’s coming report is due at the end of the year. Conclusion As it stands, Vermont is the only state that placed a potency cap on legal recreational cannabis. Meanwhile, an attempt at such has failed woefully in Massachusetts and South Dakota.

Attempts at a long-lasting potency cap have proven difficult due to strong pushbacks from the cannabis industry. Many within the industry have claimed that proof backing the widespread risks of high THC levels are scant and more research needs to be done.

However, Carlini has stood by her team and the research they executed saying she and her team stand by the conclusion reached. The higher the THC levels of cannabis, the higher the chances of dangerous side effects.
