How many years of taking amphetamines causes damage?

The duration of amphetamine use that leads to damage can vary significantly among individuals and depends on factors such as dosage, frequency of use, and individual susceptibility. Some studies suggest that even a few months of regular use can result in changes to brain structure and function, while chronic use over several years is more likely to cause severe cognitive deficits and mental health issues. It's important to recognize that the risk of damage increases with higher doses and prolonged use. If you or someone you know is struggling with amphetamine use, seeking professional help is crucial.
