Smoking - Cocaine not hardening after cook?

[Blackest Death]

In all the years SWIM has been cooking in a spoon this has never happened to him. The coke is really good or so it would seem and with a touch of soda/water it cooks nicley into a great tasting oil with all the expected effects. THe problem however is that it just wont harden. THe soda all falls to the bottom and will not mix with the dope at all. Not that SWIM wants too much soda in it but some would be accptable if necessary to make it rock up.

After reading Le Junk's Crack-to-Cocaine Conversion Process I noticed that there could be large amounts of benzocaine or procaine in it causing this to happen. Has anyone else encountered this? Is there a quick fix?

Any help will be greatly appreciated.
