On the rules and restrictions side of the argument, logic dictates that if it is within the law to use it, then by no means should there be a problem for its use.

On the physical side of it is that, there seem to be more harm in its usage than any undue advantage it will ever provide. It will not set the hands for heavier hitting like a plastergate will, and it can never add any power to the punches.

It does add a sense of false security in striking for volume tho, but to which end can eventually, in the future, move the drug user to a state of incapacity.

More cons than pros, in my view.
