Effects – Concentration

It is a generally accepted fact that regular and especially heavy cannabis use may lead to problems with concentration and short-term memory.

On the other hand a substantial amount of studies and patient testimonies show that medicating with cannabis helps people suffering from various mental disorders connected with inability to concentrate and keep focused, such as ADHD (attention deficit hyperactivity disorder) or autism. What is behind these contradictory effects?


Dopamine Production

One of the most renowned physicians in the field of medical use of cannabis, Dr. David Bearman, studies the relationship between human endocannabinoid system, cannabis and ADHD: “Cannabinoids seem to help patients with ADHD through an increase of dopamine production.”

Dopamine is a neurotransmitter involved in cognitive functioning, procession of memories and concentration.


Personalized Medicine

Current research needs to focus on potential effects of main cannabinoids (alone as well as in various combinations) that seem to have positive impact on disorders such as ADHD, and also study their synergic effects so that the breeders, chemists and health professionals are able to provide the most suitable strains (i.e. precise cannabinoid content) according to individual needs of each individual patient.


Everything in Moderation

At the same time it is vital to remember that heavy and regular use (especially of strains with high THC content) may not only worsen short-term memory, but also seriously affect one’s ability to stay focused even on a long-term basis.
