Where i live almost every k users here believe that k need to be heated up before snorting. I have yet met anyone who think otherwise

K here is mostly in rock form, powder is also available but harder to find, shard is super rare and vial is extremely rare.

So what we do is to crush the rocks into grains then put them on cotton bill note and use a lighter to heat up the crushed ketamine, make sure not to burn the bill. Make a few passes of the flame then stop and stir, repeat 3-4 times or until you can smell the ketamine. Timing under the flame is vary from person to person. But they all believe that ketamine need a specific amount of heat to give you the best high possible, too little heat wont give you the best high and too much heat will give you headache and confusion when use

This is widly know across the country to the point everyone accept it as fact. I think most of people in here would have very different thought. But is there more to this? Maybe those rocks are not exactly ketamine but something else? Or maybe it's somewhat true?
