no its not the acitve ingredient in shrooms because heat destroys pshycolobin (spelling) which is the main physcoactive ingredient in shrooms id tell him you know this and ask again what is in it because you dont want to be smoking weed that is laced with something that you dont know what it is and that he is lying about. u cant get anything from smoking a magic mushroom if the black specs are big enough take them out and burn it itself and smell the smoke he may just be putting bits of crushed black pepper in it and charging more or using it to say his weed is better i hope this helps
