The Deep Dive
As tolerance develops, the margin of safety narrows, meaning that an individual needs to consume more of the substance to achieve the same effect, increasing the risk of overdose. Essentially, the body adapts to the presence of the drug, making it less effective at lower doses, which can be dangerous.
Vivian’s experience of shaking, sweating, pain, and headaches is a clear indication of withdrawal symptoms. When a person who is dependent on a substance suddenly stops using it, their body reacts negatively, and these symptoms can vary widely in intensity and duration, showcasing the body’s struggle to adjust to the absence of the drug.
