Long-term effects of early THC consumption
In this field of research, we found empirical evidence for the claim that early (around onset of puberty) and regular THC users may suffer from long-term deficits of visual orientation (oculomotor control) later in life. These specific deficits are demonstrated by measuring performance in basic oculomotor tasks. Crucially, these deficits also appear to affect performance in everyday activities that necessitate efficient oculomotor control, such as reading or visual search.
