sure you do not take ritalin up the nose, but someone who isnt you may.

swim has read about kids dieing from cardiac arrest from ritalin, but they were merely taking it orally daily for AD(H)D;

not so personally, swim likes adderall more, has more euphoria w/ it...ritalin just makes him irritable.

HEALTH CONSEQUENCES
Ritalin (methylphenidate) is a central nervous system stimulant, similar to amphetamines in the nature and duration of its effects. It is believed that it works by activating the brain stem arousal system and cortex. Pharmacologically, it works on the neurotransmitter dopamine, and in that respect resembles the stimulant characteristics of cocaine. When taken in accordance with usual prescription instructions, it would be classified as having mild to moderate stimulant properties, but when snorted or injected it has a strong stimulant effect.

Even when taken according to the prescription directions, there is a risk of developing dependence and tolerance to the drug. The manufacturer cautions physicians to be on the lookout for the following adverse effects:

nervousness and insomnia;
loss of appetite, nausea and vomiting;
dizziness, palpitatons, headaches;
changes in heart rate and blood pressure (usually elevation of both, but occasionally depression);
skin rashes and itching;
abdominal pain, weight loss, and digestive problems;
toxic psychosis, psychotic episodes, drug dependence syndrome; and
severe depression upon withdrawal.

High doses of stimulants produce a predictable set of symptoms that include:

loss of appetite (may cause serious malnutrition);
tremors and muscle twitching;
fevers, convulsions, and headaches (may be severe);
irregular heartbeat and respirations (may be profound and life threatening);
anxiety, restlessness;
paranoia, hallucinations, and delusions;
excessive repetition of movements and meaningless tasks; and
formicaton (sensation of bugs or worms crawling under the skin).
While death due to non-medical use of Ritalin is not common, it has been known to occur.

In order to make the 5- to 20 mg. dose tablets large enough to handle easily, at least 100 mg. of "inert ingredients" are added to the tablets to increase their size. Depending upon size and formulation, the following inert ingredients are found in Ritalin tablets, according to the manufacturer: lactose, starch, polyethelene glycol, magnesium stearate, sucrose, talc, cellulose, mineral oil, and various dyes and conditioning agents. While these ingredients are "inert" when taken by mouth, they can cause serious problems when injected or snorted.

This is odd.... swim never ever could stay awake on 30mg of ritalin taken once... it´s out of your system in 4 hours... let it be 6 and that´s it.

bioavailaility comes to mind by short-cutting the first pass metabolism, but still.... naaahh.
