There have not been any clinical studies done on the risks of snorting Concerta, but it is likely to be more dangerous than taking it by mouth. When snorting or injecting drugs, it allows for direct entry into the bloodstream, making the drugs more potent and more dangerous. In addition, Concerta is not sterile, and injecting or snorting it may lead to infections or other problems.
Concerta® (methylphenidate extended release) is a prescription medication used to treat ADHD. It is also a medication that is commonly abused. Concerta is meant to be taken by mouth. Although the safety of snorting Concerta has never been studied, it is likely to be more dangerous than taking it by mouth.
There are many reasons why Concerta is snorted. It is a stimulant (or an "upper") that people can easily abuse. Another reason Concerta is snorted is for weight loss. Weight loss is a common side effect of methylphenidate (the active ingredient in Concerta). Because Concerta is a commonly prescribed medication, it is often easy to find.
Many people mistakenly think that snorting (or otherwise abusing) Concerta is safe, because Concerta is a prescription medication, not a "street drug." Many people who abuse Concerta take very high doses, much higher than would be normally prescribed. Also, people who snort or inject normal doses of Concerta are putting themselves at higher risk. Snorting or injecting drugs allows for direct entry into the bloodstream, making them more potent (and more dangerous). Also, Concerta is not sterile, and injecting or snorting Concerta may lead to infections or other problems.
