Not that fast.: Marijuana may cause some chemical or physiological changes after long time use, but not in 4 uses. Marijuana can hang around in your body system for several weeks, due to its high lipid solubility, but I suspect things should clear up for you in a few days. I am not sure how strong that weed was, but the demographics suggests a male to the name Shirley303. Hmmmm.

Be Wary of Weed: Marijuana coupled with other agents like hallucinogens can result in occasionally long lasting side effects. Chronic use can result in permanent damage to the brain and affect cognitive function and memory. Marijuana has also been noted to make changes in the lung similar to tobacco, resulting in chronic disease. The eyes are the windows to the brain and the mind; get checked if persistent.
