Mephedrone is an amphetamine-like drug, and like other stimulants, can lead to a variety of symptoms including dizzines, headaches, and in severe cases even seizures, stroke or bleeding in the brain, vasopasm (abnormal constriction of the blood vessels in
the brain) and vasculitis (inflammation of
the blood vessels in
the brain).
The majority of these adverse effects occur at higher doses and with sustained use, but can occur even with small doses.
