Yes, but is it paco, or is it real Cocaine that has not yet been fully processed. There is a big difference. Cocaine paste is the last step before turning it into Cocaine Hydrochloride. Paco, which I'm told is popular in some parts of South America, is a more adulterated, dangerous version of Cocaine, which hasn't been prepared or extracted properly and still may contain some of the harmful ingredients involved in the synthesis.
Have you tried letting it air dry or in an oven on a relatively low heat? Research into melting points and such before applying any kind of excessive heat to your drugs.
