many people here may already know about this but there might be some that don't. ok you have a pill in your possession and you are wondering if it has recreational value. you go to erowid to look in their pharms list only to see that it isn't listed. well here's what you do. go to google and type in "name of drug" (no quotes) site:erowid.org doing this i have found erowid's page for propoxyphene which isn't listed in their pharms section. I have also used this method for other pills to see if they held any recreational value.
I really don't suggest Erowid as the best site for Pharm experiences. Use something more user-based, like a forum dedicated to Pharms. Opiophile.org Bluelight.ru Erowid is on the slow end when it comes to learning about things, and it USED to be one of the best places for really good info, but I really think forums are a much better resource. Regardless, that is a pretty cool tip, thanks for that! Most of the good recreational drugs should be listed, it's funny Darvocet isn't. I know it isn't considered "good," but they have a lot of substances, and it's really odd that you can't find that by just browsing the site.
adding on to what meatwagon said: if you put pill-id first (with the hyphen) and then your pill imprint, it will be alot easier and save you the hassle of browsing through links that have nothing to do with your pill.
All you have to do is put: (color) (imprint) and the word pill. Green OC80 pill You will get the results you need, and the first results will always have what you need. Pharmer.org usually is the first website to come up with results, which always relates to the search you made.
