Safe to snort Concerta?

Absolutely not
It will defeat the purpose of the drugs use by hitting you quicker but also little particles get caught in the lung and can stay and build up there causing respiratory problems later in life. Concerta was made as a po drug and crushing and snorting will cause a quicker tolerance and also you could go into a dangerous arthymia because it acts quicker. take it as prescribed or put it in ice cream but dont snort them and snorting advil will also cause resp problems from the small particles that build up. Do your self a favor and take care of your self and dont put your self at riski.
