Chemical Effects:


Marijuana as most of the other drugs stimulate brain cells to release de chemical dopamine, the neurotransmitter responsible for emotions, movements, humor, etc. People who are under THC effects get euphoric and have heightened sensory perception, e.g.: they see brighter colors. Brought by the blood stream to the brain, it also blinds with the cannabinoid receptors in the brain that control perception, so they have a distorted perception.

Vision:
The eye is the organ of vision. It has a complex structure consisting of a transparent lens that focuses light on the retina. The retina is covered with two basic types of lightsensitive cells-rods and cones. The cone cells are sensitive to color and are located in the part of the retina called the fovea, where the light is focused by the lens. The rod cells are not sensitive to color, but have greater sensitivity to light than the cone cells. These cells are located around the fovea and are responsible for peripheral vision and night vision. The eye is connected to the brain through the optic nerve. The point of this connection is called the "blind spot" because it is insensitive to light. Experiments have shown that the back of the brain maps the visual input from the eyes.

THC increases the blood pressure and vasodilatation and the pupils widen.

Taste:

The receptors for taste, called taste buds, are situated chiefly in the tongue, but they are also located in the roof of the mouth and near the pharynx. They are able
