What's something a lot of ents are doing wrong but don't know it??

I think its important that if someone is spending money consistently on weed they should know how to get the most bang for their buck. I've met people who smoked daily didn't know that they should clear the piece after a hit, totally changed their smoking. What's something a more seasoned ent might need to know about??

PS. Just finished a bowl out of a bubbler and about to rock a Pax, smoke on [5}
