Further effects include: a racing heartbeat, palpitations, chest pain, agitation, excessive sweating, raised temperature, headache, nausea, abdominal pain, tremor/shaking and elevated blood pressure.
Anxiety, dizziness, sleep disturbances, teeth grinding, muscle twitching, poor concentration, depression and short term memory loss are also common following the use of stimulants, which frequently affect mental health.
Convulsions, hallucinations, and skin rashes have also been reported in some users. Nasal irritation and nose bleeds may occur after snorting/keying or inhalation.
In severe cases, stroke, heart attacks, kidney failure and liver damage may occur after the use of ethylphenidate and other similar compounds to amphetamines.
