The Link Between IQ & Weed Consumption

Cannabis, a plant known for its psychoactive properties, has long been a subject of intrigue and debate. One aspect that has captured the interest of researchers is the potential link between higher intelligence quotient (IQ) and cannabis consumption. While it’s important to approach this topic with an open and critical mind, several studies have suggested a correlation between higher IQs and a propensity to consume cannabis. In this blog, we will explore the findings of these studies, the potential reasons behind this correlation, and the implications it may have.

The Studies

James W. White’s Research

In 2011 and 2012, James W. White conducted two significant studies that delved into the relationship between intelligence and cannabis consumption. These studies involved 3,818 men and 4,128 women, spanning the ages of 16 to 30. Participants were regularly monitored to gather data on their marijuana habits and overall intelligence.

The findings from these studies indicated a noteworthy connection. People with higher IQs were more likely to consume cannabis. While these results are intriguing, they raise an important question: What might be driving this correlation?

Women and Higher IQs

In 2017, researchers from the Journal of Epidemiology and Community Health conducted a study focusing on 800 female cannabis consumers. The goal was to examine the connection between their intelligence, smoking habits, lifestyle, and educational background. The results indicated that female cannabis consumers, on average, had higher IQs compared to the general population. They were found to be 50 percent more intelligent than the average woman.

Possible Explanations

Seeking New Experiences

One potential explanation for the link between high IQs and cannabis consumption is the desire for new experiences. Intelligent individuals may be more inclined to explore various modes of thought and consciousness that cannabis can provide. This suggests that higher intelligence may correlate with a penchant for diverse mental stimulation.

Evolutionary Psychology

Satoshi Kanazawa, a writer and psychologist, proposed an interesting perspective. He suggested that the consumption of cannabis might be rooted in evolutionary psychology. According to Kanazawa, cannabis could offer stimulation that encourages human progress and adaptation to changes. In essence, the plant may act as a catalyst for creativity and innovation, qualities associated with higher intelligence.

Decision-Making Ability

Clinton B. McCracken, an expert in substances such as cannabis, posits that individuals with higher IQs may be better at discerning what can or cannot affect them. This enhanced decision-making ability could lead them to make more informed choices about cannabis consumption and its potential effects on their well-being.

Social Adaptation

On the flip side, some experts believe that the correlation may be related to social adaptation. Isolation, often experienced by exceptionally intelligent individuals from a young age, might drive them to seek new experiences to overcome boredom and social challenges. Cannabis could serve as a means of coping with social isolation or as a tool for connecting with like-minded individuals.

Trends and Cultures

Lastly, the link between high IQs and cannabis consumption could also be influenced by trends, cultures, and specific moments in time. Cultural shifts and changing attitudes toward cannabis might play a role in this relationship. For example, during periods of increased acceptance and legalization of cannabis, more intelligent individuals might feel more comfortable experimenting with it.


While the correlation between high IQs and cannabis consumption is intriguing, it’s crucial to remember that correlation does not imply causation. These studies provide valuable insights, but more research is needed to establish the reasons behind this phenomenon definitively.

Moreover, it’s essential to approach cannabis consumption responsibly, considering its potential effects on cognitive function and emotional maturity, especially among younger individuals. As we continue to explore the complex relationship between intelligence and cannabis, let’s remain open to new findings and perspectives while prioritizing informed decision-making.

In the ever-evolving landscape of cannabis research, it’s important to approach this topic with a curious and critical mindset. While intelligence and cannabis consumption may indeed be connected, the full extent of this relationship is still shrouded in mystery. As science delves deeper into the subject, we can anticipate further revelations that may shed more light on this intriguing phenomenon.
