Throughout history, marijuana has been and remains frequently associated with artistic creativity and innovation. It has been used by great writers, painters, musicians, and even chefs. The idea that it serves as a catalyst for brilliant ideas and unfettered creativity has permeated popular culture and persisted to such an extent that numerous scientists have explored the topic. Does marijuana influence creativity, and if so, to what extent?

Can creativity be measured scientifically?

No, but the factors that influence it can be carefully examined, and scientists now know enough about the human brain to allow them to attempt to test whether marijuana has an effect on changing thinking processes.

What is creativity in the thinking process?

Creativity is based on two important ways of thinking – divergent thinking and convergent thinking.

The former is responsible for creating loose associations and searching for new, original ideas. The latter is associated with integrating them and finding the best common solution. Their combination constitutes the ability to think creatively.

Some scientists note that dopamine plays the most important role in this, which is an important neurotransmitter. THC clearly affects its levels, which leads to an increase or decrease in specific thinking abilities.

In the case of divergent thinking its level suggests an inverted "U"„, which means that too little and too much dopamine will negatively affect creativity, which limits the ability to create innovative ideas.

Optimal value brings success in innovative thinking. In the case of convergent thinking, dopamine increases may hinder concentration and analytical skills, but it has advantages in unconventional approach to the issue.

What conclusion can be drawn from this? Marijuana in the right amount supports divergent thinking, but at the same time hinders convergent thinking.

Does marijuana stimulate creativity and at the same time limit it?

Various researchers have approached the topic in several different ways and have discovered that THC can trigger a wide range of creative responses, depending on individual characteristics, the subject's mental state, lifestyle, dosage, regularity of use, and even social and environmental factors. However, there are clear differences in the increase or decrease of dopamine and its impact on creativity.

Short-term and long-term creativity boost. On the one hand, marijuana can increase creativity, with users reporting an increase in ideas, more fluid thinking, and the ability to make non-obvious connections. On the other hand, this is only a short-term effect, and over time, when marijuana is used regularly, it can impair cognitive abilities, memory, concentration, and problem-solving.
Single dose. The effect of marijuana on creativity may also be dose-dependent. Low doses may promote creative thinking, while higher doses can lead to disorganized thoughts and difficulty concentrating, which can negatively impact creativity.

Does marijuana affect creativity? Yes, but nothing has been decided yet.

The first large-scale studies on whether marijuana stimulates creativity were initiated in the 1970s, followed by others, and the research process continues to this day.

The conclusions that can be drawn from them are as follows: Improving creativity with marijuana is a complex and individual process, which is not yet fully understood. Scientists even argue about whether it is the rise and fall of dopamine that influences thought processes.

It is clear that marijuana can have both positive and negative effects on creativity depending on many variables, but conclusive evidence is still lacking and can only be obtained through reliable studies on a large group of people taking into account many variables.
