How big of a danger are metals really?

[JackTheGrower]

dont worry to much about metals. the average modern person via teflon cooking material, drinking out of plastic bottles etc etc etc it is said ever 5-10 years bascially eats a cell phone worth of plastics n metals. get into flushing.................

Ah nifty avatar there and the Toke-N-Bone is way cool. I trust your are a female..

Hate to get flirty with guys being a guy myself.

So why does flushing help? I am not in the Flush-N-Toke club.

We do need to understand Cannabis is used for toxin clean ups. The plant naturally takes up toxins.

So it is best to make your own soil and maintain it with natural and safe materials.

I avoid commercial fertilizers like a plague. I mean do they really know about every scoop or cup of material they sell? I doubt it.

We can't help being exposed to toxins. We have heavy metals in our water. We can reduce our risks.

Yep. For that ability it was planted near the Chernobyl atomic power station to reclaim the land from the radioactive material...
The heavy metals are not radioactive, but are still harmful for your health.

Oh,and don't use soil that's been used as a target practice embankment.....

Definitely follow this..don't want buckshot buds

Low PH can cause a plant to uptake toxic levels of aluminum and other metals, it's one of the reasons I tend to run a bit of a higher PH (in soil).

But, like JTG said, radioactive fertilizers like rock phosphates are probably a very real danger. The danger is already known in tobacco, and there is talk about cannabis having the same reaction to rock phosphates. They're off my list, that's for sure.

The article I originally read; Winters, TH and Franza, JR. 'Radioactivity in Cigarette Smoke,' New England Journal of Medicine, 1982

I would not be overly concerned at levels present in nutes/potting soil or the relatively less harmfull elements present.

Outdoor guerilla grows on old industrial sites however could be a real problem in some long urbanised areas .

Paint factorys , dye works , brickworks , town gas cokeing plants , electroplaters and a dozen other industries have left a legacy of poisoned soil all over the Midlands UK and many other areas worlwide from a time when waste disposal meant tipping toxic waste on site or into the nearest river.

The ground on a local derelict gas site seems good and fertile with plenty of cover as it reverts to scrub , grew well there for a decade and the smoke was fine.

Now it turns out the reason it is still vacant in a prime location is the £25 million it will cost to remove thousands of tons of soil heavily contaminated with arsenic , cobalt , mercury and really nasty organic stuff from a simple three hectare site.

Have eaten hundreds of rabbits ferreted from here till this became known , along with the buds its a bit of a worry .

your body has adapted to dispose of these 'wastes' naturally. and yes they are waste if provided in overabundance! All living cells require pretty much the same nutrients.
pine needles are a lead sink and litter the vast areas hiding outdoor grows, so how do you know if you are consuming some of that primo outdoor smileyshit or not? Unless you grow.
most if not all chemicals added as fertilizers are moleculerly identical to naturally occurring organic compounds after being denitrolized by soil microbes into chelated form.
what are you ingesting that is not provided in similar amounts in the vegetables and fruits that are watered by the rain that washes the chemicals and metals from the air?
are those healthy alternatives to fast food poisoing you too!? That IS scary.
