I knew someone who was scared to go to the dentist and be administered it because he was in AA when I was forced to go. Just in case your pulling a leg I need a few things...
1. Please provide a pic (holding in you hand, not the ones on the net)
2. If you do have it then could you tell me why you are prescribed it? I mean, yes, it is VERY rarely indicated for specific reasons (after having them removed is not) I guess during your wisdom teeth extraction but why were you prescribed it? Continued on the next question...
3. Cocaine solution/topical has been largely replaced by synthetic local anesthetics such as benzocaine, proparacaine, lignocaine/xylocaine/lidocaine, and tetracaine. So why were you given it? It isn't "prescribed" for wisdom teeth" pain. They administer narcotics and benzodiazepines (as needed) after you leave. Cocaine is rarely prescribed for "anesthesia", not so much pain.
4. Although cocaine is an acceptable topical anesthetic for dental procedures, it is no longer extensively used in dentistry because of its toxicity. There is about two reasons why it is prescribed, going home because of wisdom removal, not really one.
BUT whether or not you were actually prescribed it, I'll try to answer your question. Is the solution clear? If so, do the same is if you were cooking ketamine. Pour a large pan with water and wait until it starts to boil. Take out a flat pyrex plat and pour the solution on it. Put the pyrex plate with the solution on top of the boiling pan. Wear gloves because you'll want to move around the plate slowly in a circle o that you get the solution around the plate. It will turn to dry paste. Once it completely does, remove the plate. If you leave the dry paste for too long it may start to turn drown. Now your ready to get a razor blade and scrape ALL the dry paste into fluffy powder. Remember that the powder is pure and you will only need to snort roughly 1/10th of what you have to get high, considering you have the 10ml 100mg solution.
This is *only* if the solution is completely clear.
