1
For centuries, humans have been using substances to alter their state of mind.
2
From caffeine, cigarettes and alcohol to more extreme drugs.
3
But as the most commonly used illicit drug in North America, Where does marijuana fit in and how exactly does it affect your brain?
4
First, we need to understand how the brain functions.
5
Neurons are the cells that process information in the brain.
6
By releasing chemicals called neurotransmitters from the axon of one neuron to the dendrite of another they change the electrical charge of the receiving neuron consequently exciting or inhibiting it.
7
If excited, the signal is passed on.
8
Though it sounds simple these signals work together and the effect is quickly compouned into complex configurations within milliseconds flashing over the entire brain.
9
This is what happens every single time you think, breathe or move.
10
So what is going on inside your brain when you’re smoking marijuana?
11
Well unlike alcohol, which contains molecules nothing like those in our body, cannabis contains molecules that resemble those produced in our very own brains: cannabonoids.
12
Although naturally these cannabonoids circulate at much lower quantities compared to the large influx imposed by smoking, specifically the chemical tetrahydrocannabinol or THC resembles a natural transmitter called “anandamide”.
13
These cannabonoids are specialized neurotransmitters released by neurons having just fired.
14
Neurons temporarily become unresponsive after firing to prevent them from overracting or being too dominant.
15
This allows your brain to function in a calm and controlled manner.
16
But cannabonoids interrupt this approach in some parts of the brain.
17
Instead, they remove the refractory period of neurons that are already active and can cause your thoughts, imagination, and perception to utterly magnify itself.
18
This means, once you begin your train of thought it becomes the most significant and profound thing ever.
19
You can’t see the big picture or even recall your last epiphany because you’re caught up in the momentum of a particular idea and your neurons keep firing until a new idea takes hold and you go off on a new tangent.
20
These cannabonoids also affect the levels of dopamine and norepinephrine in your brain often leading to a sense of euphoria, relaxation, pain modulation and general enhancement of an experience, though sometimes causing anxiety.
21
Furthermore, there are cannabonoid receptors in areas controlling short-term memory, learning, coordination, movement control and higher cognitive functions.

What is the Shadowing Technique?

Shadowing is a science-backed language learning technique originally developed for professional interpreter training and popularized by polyglot Dr. Alexander Arguelles. The method is simple but powerful: you listen to native English audio and immediately repeat it out loud — like a shadow following the speaker with just a 1–2 second delay. Unlike passive listening or grammar drills, shadowing forces your brain and mouth muscles to simultaneously process and reproduce real speech patterns. Research shows it significantly improves pronunciation accuracy, intonation, rhythm, connected speech, listening comprehension, and speaking fluency — making it one of the most effective methods for IELTS Speaking preparation and real-world English communication.
