mwa, I dont have any objection to make it like this but I cant hear people saying that we are in danger, that is crazy. I always search before I make anything for GG and I said why we are not in danger. If we think like this then e-smoking is extremely dangerous with all those metals we use and we touch them all the time with out hands, connectors are dangerous, steel is dangerous because it rusts too but slower and it contains iron, carbon, chromium, nickel, niobium, molybdenum, and titanium, atomizer connectors are dangerous because they are made from brass or zama, nickel and chromium are dangerous (if you search google about chromium you will shudder but coil inside atomizers is made from nickel-chromium alloy, rope is dangerous because its made from silica, PG is dangerous if it is inhaled, etc. Aspirin is also very dangerous (read the description about aspirine).
Its true that we try to avoid anything that hurt us, thats why we vape and we dont smoke. As for brass my final conclution is that brass is antimicrobial and its totally safe inside liquid. I dont say that we can lick it as we cant lick aluminium, steel, nickel, chromium etc, but I say that its more than ok where we use it.
