Fatal Vision Marijuana Goggles model the effects of recreational marijuana so you can experience the impact of what it’s like to be under the influence. Marijuana affects the brain differently than alcohol, and our marijuana goggles reflect that difference. Rather than distorting the vision so the participant stumbles and loses coordination, the goggles simulate marijuana’s true effects — they diminish the participant’s capacity to make quick, accurate decisions, and that causes her to miss important external cues that could lead to an accident. The goggles accomplish this by impairing her ability to perceive the color red. This lack of perception means the participant does not have all the necessary information to complete specially designed activities. When you are under the influence of marijuana, you do not, in fact, lose your ability to perceive the color red.
