Image 1Shows how the cannabinoids bind to receptors

in order to active the effect of marijuanaYou can also see the similar cell structure of the

marijuana to naturally occurring cells in the body

For this reason the receptors accept the cannabinoids

Image 2• THC (delta-9-tetrahydrocannabinol) is

marijuana’s main active ingredient. • Scientists identified the sites in the brain and

body where marijuana acts and called them cannabinoid (CB) receptors.

• Cannabinoids are important because they influence how cells communicate

Image 3&4This shows the chemical structure of the

CannabinoidIt also displays a zoomed in depiction of the

body synthesizing the cannabinoid and THC

Image 5Takes apart different parts of the brain, and how

marijuana effects them differentlyEx: Amygdala on marijuana causes paranoia,

but the Hippocampus causes impaired memory

Image 6Similar to the last image it shows how the brain

has various functions and how they are impacted by marijuana

THC travels to the brain and can effect coordination, memory, judgment, and even pleasure

Image 7One of the most informative images explains the

receptors points, and visually shows how the THC connects to the Cannabinoid receptor

It also discusses consequences to your brain from marijuana

An interesting point at the bottom is made about dependence after one use. 9% of people claim they are dependent after one use

Image 8The bodily effects are seen in this imagePeople often get red eyes, dry mouth, and have

a rapid heart beat

Image 9• When someone smokes marijuana, THC

stimulates the CBRs artificially, disrupting function of the natural, or endogenous, cannabinoids.

• An overstimulation of these receptors in key brain areas produces the marijuana "high," as well as other effects on mental processes.

Image 10This shows how the effects of consuming

marijuana rather than smoking it are much slower and longer lasting

Also, the potency of THC is much higher when it is smoked instead of consumed
