How does cannabis affect the brain?

Some do it daily, some even several times a day. There are stoners for whom a joint is part of everyday life as naturally as butter on bread or coffee with cake.
The brain of these Cannabis users is constantly flooded with THC, the main active ingredient in cannabis.
This is especially true when using highly potent cannabis strains.

How harmful is cannabis to the brain?

There are a number of partially contradicting research results on the question if and how harmful is cannabis to the brain.
For this reason, researchers from the Center for Medical Cannabis Research at the University of California collected and analyzed all available research results on the neurocognitive effects (effects on the brain) in long-term users in 2003
Few studies provide reliable results.
Of the 1,014 studies identified that examined neurocognitive functions in cannabis users, only 15 studies could meet methodological criteria that produce reliable results.
These 15 studies include 704 long-term cannabis users and 408 non-users.
The neurocognitive studies, examines the response time, learning ability, memory and attention and no brain damage was found – but impaired learning and memory performance where low.

After summarizing and analyzing all the results of the study, the researchers came to the conclusion that there was no substantial loss in cognitive brain functions.

However, there were slight losses in the areas of learning ability and memory.
“Surprisingly, we have hardly found any evidence of harmful effects (related to brain performance).

The only exception is an extremely small effect when learning new information, “said Prof. Igor Grant, head of the study.

In addition, the restrictions in brain performance that were found could not be attributed with absolute certainty to cannabis, since the consumers may also have previous burdens – e.g. have had
