Marijuana has both short- and long-term effects on the body.
Within a few minutes of smoking marijuana, a person feels the effects of pot, as THC is rapidly passes from the lungs into the bloodstream, making its way to the brain and other organs.
What causes the “high” people experience is marijuana’s effect on over-activating parts of the brain containing specific brain cell receptors. This leads to feelings of an altered sense of time, other altered senses, changes in mood, impaired body movement, impaired memory and difficulty in thinking and problem-solving.
Researchers are still studying the long-term effects of marijuana. But what is known is that the younger a person begins using pot, such as in the teen years, the greater the declines in general knowledge, impaired thinking, learning difficulties and lowered IQ.
