Since methamphetamine and other amphetamine-type stimulants (meth/amphetamine) can damage dopaminergic neurons, researchers have long speculated that these drugs may predispose users to develop Parkinson's disease (PD), a dopamine deficiency neurological disorder.

The meth/amphetamine cohort showed increased risk of PD compared to both that of the matched appendicitis group [hazard ratio (HR) = 1.76, 95% CI: 1.12–2.75, p = 0.017] and the matched cocaine group [HR = 2.44, 95% CI: 1.32–4.41, p = 0.004]. The cocaine group did not show elevated hazard of PD compared to the matched appendicitis group.

These data provide evidence that meth/amphetamine users have above-normal risk for developing PD.
