Well… it is a tar derivative, so considered a carcinogenic. ;)
But many people take it successfully. There are other binders like bentonite clay (also a tar derivative) and cholestyramine (Rx required). As long as you stick to the buffer periods are not feeling a herx or worse when taking the charcoal, your dose is probably ok. But yes, you can take too little and too much of any binder. If you're more comfortable with a lower dose try it and see if there is much change.
