An overdose happens when you consume too much of a substance that your body can't handle it. Although there are plenty of reports of people overdosing on cocaine, meth, heroin, and other drugs, it is possible to overdose on shrooms.
However, a mushroom overdose is rarely fatal. Instead, you might experience symptoms like dizziness, muscle weakness, lightheadedness, anxiety, psychosis, excessive sweating, agitation, and confusion.
One problem about ingesting mushrooms is the lack of standard formulations, making it difficult for the average person to know exactly how much you have consumed. Additionally, there are some strains that are more potent.
