Does Marijuana Lower IQ?

Recreational. Medical. Research. Bias. Four of these are based on sound principle while the last relies on emotion and preconceived judgment to sway logical opinion. MATFORCE, an organization out of Yavapai County, AZ has been posting billboards against marijuana since earlier this year. Their first billboard questioned whether our children would know if a cookie contained marijuana. It’s a valid question with an easy answer that begins with good parenting and ends with responsible marijuana packaging. After a social media fiasco, the company replaced the billboard with another that claims marijuana lowers IQ.

A Google Scholar search sheds some light on this issue. The methods and procedures for most of the studies I dug into improperly utilized the scientific method. However, one study performed MRI and PET scans to explore marijuana’s relationship with our brain morphology. The researchers found that patients who began use in their teens compared to early twenties had decreased grey cortical matter and increased white cortical matter. They also found increased levels of cerebral blood flow (which is a good thing).

The IQ tests used in many of the studies focused on a single metric without accounting for other variables associated with the age range studied. Alcohol, cigarettes, recreational drugs such as cocaine and heroin, and prescription pill use all have to be considered when looking into IQ. There is controversy surrounding IQ measurements and methods to test for it. Any study attempting to link IQ and marijuana should take into account the different types of IQ: logical, spatial, visual, musical, interpersonal, and intrapersonal.

So what does this mean?

Grey matter is the outer layer to our brain and surrounds the spinal cord brain tissue with unmyelinated (non-insulated) tissue. It’s primarily associated with cognition, speech, emotions, motor movement, and the senses.

White matter is the inner layer and consists of long myelinated (insulated) axons, or nerve fiber bundles, that transmit information throughout the CNS. Grey matter processes information and white matter transmits it.[/fusion_text][/fusion_builder_column][/fusion_builder_row][/fusion_builder_container][fusion_builder_container hundred_percent=”yes” overflow=”visible”][fusion_builder_row][fusion_builder_column type=”1_2″ last=”no” spacing=”yes” center_content=”no” hide_on_mobile=”no” background_color=”” background_image=”” background_repeat=”no-repeat” background_position=”left top” border_size=”0px” border_color=”” border_style=”” padding=”” margin_top=”” margin_bottom=”” animation_type=”” animation_direction=”” animation_speed=”0.1″ class=”” id=””][fusion_imageframe lightbox=”no” lightbox_image=”” style_type=”none” bordercolor=”” bordersize=”0px” borderradius=”0″ stylecolor=”” align=”none” link=”” linktarget=”_self” animation_type=”bounce” animation_direction=”down” animation_speed=”0.8″ hide_on_mobile=”no” class=”” id=””] [/fusion_imageframe][/fusion_builder_column][fusion_builder_column type=”1_2″ last=”yes” spacing=”yes” center_content=”no” hide_on_mobile=”no” background_color=”” background_image=”” background_repeat=”no-repeat” background_position=”left top” border_size=”0px” border_color=”” border_style=”” padding=”” margin_top=”” margin_bottom=”” animation_type=”” animation_direction=”” animation_speed=”0.1″ class=”” id=””][fusion_text]Myelin is the key difference between the two fibers as it directly affects motor coordination and effectiveness of traveling nerve signals. Like an insulation to a cabling inside a music studio, healthy myelin structure and growth are crucial for signal transmission.

We know from research that myelin deterioration is directly related to movement disorders such as multiple sclerosis as well as cognitive impairments that occur with age. We also know that learning new skills and motor movements are directly related to white matter. THC is effective at treating these disorders of muscle movement precisely because of the findings that the morphology study implied. The increase of white matter means an increase of overall myelin levels and, physiologically, this is amazing news![/fusion_text][/fusion_builder_column][fusion_builder_column type=”1_1″ background_position=”left top” background_color=”” border_size=”” border_color=”” border_style=”solid” spacing=”yes” background_image=”” background_repeat=”no-repeat” padding=”” margin_top=”0px” margin_bottom=”0px” class=”” id=”” animation_type=”” animation_speed=”0.3″ animation_direction=”left” hide_on_mobile=”no” center_content=”no” min_height=”none”][fusion_imageframe lightbox=”no” lightbox_image=”” style_type=”none” bordercolor=”” bordersize=”0px” borderradius=”0″ stylecolor=”” align=”none” link=”” linktarget=”_self” animation_type=”0″ animation_direction=”down” animation_speed=”0.1″ hide_on_mobile=”no” class=”” id=””] [/fusion_imageframe][/fusion_builder_column][/fusion_builder_row][/fusion_builder_container][fusion_builder_container background_color=”” background_image=”” background_parallax=”none” parallax_speed=”0.3″ enable_mobile=”no” background_repeat=”no-repeat” background_position=”left top” video_url=”” video_aspect_ratio=”16:9″ video_webm=”” video_mp4=”” video_ogv=”” video_preview_image=”” overlay_color=”” overlay_opacity=”0.5″ video_mute=”yes” video_loop=”yes” fade=”no” border_size=”0px” border_color=”” border_style=”” padding_top=”20″ padding_bottom=”20″ padding_left=”0″ padding_right=”0″ hundred_percent=”no” equal_height_columns=”no” hide_on_mobile=”no” menu_anchor=”” class=”” id=””][fusion_builder_row][fusion_builder_column type=”1_1″ background_position=”left top” background_color=”” border_size=”” border_color=”” border_style=”solid” spacing=”yes” background_image=”” background_repeat=”no-repeat” padding=”” margin_top=”0px” margin_bottom=”0px” class=”” id=”” animation_type=”” animation_speed=”0.3″ animation_direction=”left” hide_on_mobile=”no” center_content=”no” min_height=”none”][fusion_text]Raise your hand if you use cannabis to:

  • Study
  • Play an instrument
  • Workout
  • Enjoy the outdoors

Perhaps you notice that it’s easier to focus on the task you set yourself to. For the active group, do your workouts become more intense and rewarding? In nature, is it easier to appreciate the moment instead of thinking of work and other responsibilities you left in the city?

Since becoming a medical marijuana patient, I have learned to play the drums, produce music, yoga, found a passion for writing and poetry, and taught myself how to dribble a basketball (a long time childhood goal).

IQ is measured in more than rudimentary tests. It’s more than simply processing information and regurgitating the same. IQ is the words that we use to communicate with others, how we physically manipulate our environment, emotionally connecting with those around us, and, of course, our ability to logically understand the world.

MATFORCE should heed their own advice and think again.[/fusion_text][/fusion_builder_column][/fusion_builder_row][/fusion_builder_container]
