Holding hits does nothing but damage. A natural breath is roughly 3 seconds, you shouldnt have to hold it any longer than that. If you do your damaging your brain, your lungs... everything!

Theres no THC to be absorbed... it's absorbed instantly... so all holding it does is coat your lungs in a lovely thick tar, and while your not breathing... no oxygen... and what does that mean? It means not breathing turns people into vegtables.

Dont hold your hits... theres no point at all... unless you want to be ill.
