This formula was quite effective in protecting the wood but had issues with toxicity, not only for those who worked with the wood but also for any animals that came into contact with the lumber. For instance, dogs that chewed on the wood often succumbed to toxic arsenic poisoning. As a result, early in the 21st century, wood manufacturers began experimenting with other formulas, primarily Alkaline Copper Quartenary or ACQ lumber.

While this new ACQ-treated lumber did not have the issues with the toxicity of the traditional formula, the new pressure-treated lumber had its own problems. In particular, the high levels of copper in the material made it far more conductive, causing increased levels of corrosion in the material as it reacted with traditional nails and wood screws.

Since warped lumber doesn't sell, manufacturers want to get the wood to the lumberyard or home center as quickly as possible with all of the wood dripping wet so that it will sell before it begins to dry unevenly.

When wet, wood acts like a sponge, with the fibers forming the grain along the long axis of the tree trunk soaking up as much liquid as possible.
