I've always been apprehensive sharing how to hit with newcomers. I've rarely given a wakeup on the street as I never wanted to be the one to get someone started.
Years ago my lady refused to fix my pipe for me. She was a scientist with this shht lol she just didn't want me to get that massive blast and she would feel guilty if I began selling my a$$ for crumbs of another hit!
Today, here I am cheeks still preserved yet I have in my own right mastered a good blast.
My advice, throw it away. As a beginner it's much easier to mess up your hit than it is to get a decent hit. There is truly a science behind hitting crakk especially in a stem. Heat, flame control, breath control, size and quality of chore, quality of rokk, size of rok, clean apparatus, broken apparatus and so on.
Nothing will have the average crakk smoker back out in the wilderness for just one more than a messed up hit. I had a companion tell me "I'll give you my last 10$ before I give you my last hit" as the street veteran she was she kept her word and gave me $10!!
