I use my Volcano and hold my hits in for around 30-50 seconds that is when it turns into a ghost hit, for thick clouds at a min it should be a ghost hit, regardless of size.
I been practicing the 45 second inhale/exhale thing and already seeing vast improvements and lungs feel really healthy...
Is it worth getting oil to use it in the volcano?
I have never tried hash oil before, so will it be significantly higher than I would be with dank weed?
& will it be saving
