Yes, like many other prescription drugs and illicit substances, Valium can be ingested by snorting the drug. However, the drug was designed to be swallowed and patients should also follow the recommended usage instructions given to them by a doctor or pharmacist. Many people who have attempted to snort Valium report that the drugs delivered the same potency and worked just as well when swallowed. Because diazepam is a lipid soluble drug, it is not absorbed that well when snorted.
