I worked in an electroplating plant for a couple of years in my younger days and worked with sulphuric, hydrochloric, hydrofluoric acids among others as well as a whole range of caustics alkalines and as a result, I don't want anything I ingest to have been anywhere near sulphuric acid.
I have no doubt you get results using it Stoney, I just wouldn't use it myself, I have seen too many things as a result of accidents with the stuff and having a stoner near a bottle is an accident waiting to happen.
I hear ya man. I figure we all drive, most of us have to use power tools and such, so if we can do that without killing ourselves, and are forewarned on it's dangers and precautions, it's no more dangerous than jacking your car up.
I worked with electroplating also. Only tin and LHE cadmium, both in aircraft production, but I know what you mean about the dangers involved with it.
I have the greatest confidence that all these stoners know when it's appropriate to be stoned or not. If legalization and decriminalisation are our goals, we have to show that we're all mature enough to use our form of medicine or entertainment responsibly as mature adults.
Growing it safely is step one in that process. Not harming ourselves in any way that is connected to the "smoking" experience is the next step.
It's kind of like using Bleach in the washer. You don't get your face down into it and you don't mix it with other household chemicals. We all know that and we obey the rules for it. It's the same with the sulfuric acid.
The hydroponic professionals of the world have said many times and in many places, that sulfuric acid is one of the best forms of pH control there is to use. The plants actually use the sulfur.
There is no risk at all to using it in the growing of weed as far as toxicity of the plant material after growing. It's used in the food growing industry all the time and is accepted for use by the FDA for hydroponic food crops. Nothing in the sulfuric acid is exchanged in smoking the plant material except the mineral "sulfur" which is in almost every food you eat and also in tobacco naturally.
