The rest of the body parts are the surgeon's assistants who are taking orders from her and can only participate in the operation under her direction and supervision. Now, imagine the brain as the control center, being clouded by the impact of marijuana. It can no longer send the correct signals and messages to the rest of the body. It is not functioning adequately as the body's control center. This is neither good for the body nor for the brain.
Serious harm can arise as a result of marijuana's interference with the brain.
Your brain gets scrambled. But, that's the lesson here. Marijuana is not harmless at all. It is a drug that is so powerful it can make the human brain incapable of doing its job. Consider this the next time you think about smoking marijuana.
