I took a baby step of 10mg maybe 6 weeks ago, with the machine and the burned and washed copper mesh. Since then the copper has been in a plastic bag in a cool dark place. Is it dangerous to use again at this time? It's not the last copper I have, but if it becomes unsafe this quickly then at this rate I'll have to cut and burn a new piece of copper every time I smoke.
and I am sure many people here would tell you the same
