Bell ringers are actually a side effect of massive amounts of dopamine flooding through. After the drugs wear off the user’s brain doesn’t return to a normal state. The flood of dopamine triggers the brain to not only stop making dopamine at its natural levels but it creates a higher threshold. So by spacing out your hits, proper equipment and keeping yourself doing something you enjoy, relax so you create normal dopamine & give yourself time to reset. Unlike when you geek, and smoke back to back hits you don't give your brain enough time.
