(TORONTO) -- People who take methamphetamine or other stimulants put themselves at far greater risk of contracting Parkinson's disease, according to a new study.
Researchers at Toronto's Center for Addiction and Mental Health said they looked over 300,000 hospital records from patients in California and learned that those hospitalized for use of meth or other amphetamines were 76 percent more likely to develop Parkinson's -- an incurable condition that causes uncontrolled tremors among other symptoms.
Dr. Russell Callaghan, who led the study, says the linkage of Parkinson's disease to meth use has been suspected for three decades but this appears to be the first conclusive proof of cause and effect.
Overdoses of methamphetamine and other stimulants in its category can result in cardiac arrest and death.
