From a Chinese Medicine perspective it is well known that Hash can be crippling for the body.
It does not give you extra Qi just because you experienced a head and body rush that was the THC in the hash nitwit.

Hash, damages the kidneys by draining it and dissipating Jing, and it totally messes up the Liver by causing qi to move in an unco-ordinated manner and then leaves you with Qi stagnation the next day not to mention it effects the Hun of the Liver massively.

If you want to bong out in your leisure time, fair enough, but don't be an idiot and think it will enhance any internal cultivation, because it will do the exact opposite, FACT!
