Insufflating (snorting) drugs of any kind has its unique dangers. Powdered substances, such as crushed Ritalin tablets, can irritate your nostrils and nose’s passageways. Additionally, it can cause pain, redness, and inflammation. Some substances can cause extreme pain when snorted. Furthermore, other contaminants can also damage your nasal passageways, in addition to chemically active drugs. If you use chronic intranasal drugs, it is possible you could lose the function of either your right or left nostril. You may lose the ability to smell or find it more difficult to breathe through your nose as you age. When snorting complications are severe, infections can spread to the lungs.
