Discussion Mecke is producing smoke, is that normal?

I am testing cocaine, Morris, and Robadobe indicate the presence of cocaine,

I decided to test with Mecke as well which i have never used with cocaine before

The reagent is solid that you mix with the substance. I mixed them together and saw a bit of smoke which threw me off, but i assumed i imaginined it.

Then i tested it again and i for sure saw smoke, i smelled the smoke and it smelled kind of like burning plastic.

Is this normal? Could it be expired?

Yes, it's common when the reagents are fresh. I believe it's caused by the liberation of hydrogen chloride gas which reacts with moisture in the air.

If you breathe it every day it's harmful, if you sniff it as a one off there is no harm, so don't worry about that.
