Oxycontin or oxycodone. Contin is the extended release, it releases the drug over a period of about 12 hours. So if you take it WHOLE, you get less mgs per hour. There is no saying what is a "safe" dose. It depends on your tolerance to opiates, your make up, and other things. www.erowid.com more specific http://www.erowid.org/cgi-bin/search/htsearch.php?method=and&restrict=www.erowid.org&format=long&config=htdig&exclude=&words=oxycontin
Depends on how fucked up you wanna get, if you got something important to do then snort 10-15 mg, if not then do a whole do or more!
