You've gotten some good answers already. However, I disagree with the poster that said sharing drug information is bad. It is exactly this sharing of info that enlightens people and keeps them in the loop of what is going on. Ignoring the drug problems in the world will not make it go away, neither will restricting the information. In fact restriction of information makes things even worse!
Back to the question:
Snorting anything usually is an efficient method of getting the drug into your bloodstream quickly. It is almost as effective as intravenous (IV) use. The drugs that are commonly snorted:
* Amphetamines - Prescription only
* BZP (Benzyl-Piperazine) - Just been banned. It is now scheduled just like Amphetamines but not used clinically except in research.
* Ritalin (methylphenidate) - Prescription only
* Ephedrine (not common) - OTC
* Cocaine - by far the most common drug snorted. Not even given under prescription. Used only in hospitals.
* Drugs like Benzodiazepines (Valium, Xanax etc) are NOT usually snorted. They are not water soluble, with the exception of Midazolam (Versed/Dormicum). I have only encountered cases of snorting with Midazolam. All of the drugs in this category are Prescription only.
* Methaqualone (Quaalude/Mandrax) - Not produced anymore except clandestinely and perhaps for research. Snorting this is a common phenomenon in certain other countries like South Africa for example.
* Yopo seeds - These are herbal psychedelics not used in medicine(yet). This particular concoction is a snuff that is made from seeds and snorted, or someone else blows it into the participants nose using a bamboo tube during Shamanic rituals
* Ketamine - Only available in hospitals, animal hospitals etc.
* Heroin - Illicit
* Oxycodone - Prescription only
Many other opioids, with the exception of Codeine and Dihydrocodeine are snorted.
Sometimes people are known to try snorting with other kinds of drugs just to see what happens (very stupid)
* Bupropion (Zyban) - Prescription anti-depressant
* Gabapentin (Neurontin) - Prescription anti-convulsant also used off-lable as a sedative
* Mirtazapine (Remeron) - Prescription anti-depressant
This is by no means a complete list, but it covers the commonly snorted drugs. Snorting might be an efficient way to deliver drugs into one's system but it is a very BAD IDEA! Not only are you snorting the drug, but you will be snorting all sorts of fillers and binders that make up the tablet. This can severely damage nasal mucous membranes and lead to infection or other problems.
Hope this helps. Feel free to drop me a line if you need any more.
