Illegal drug users get fired more frequently (4.6 percent were terminated within the past year compared to 1.4 percent of non-users). Drug users also switch jobs more frequently; 32.1 percent worked for three or more employers in the past year, compared to 17.9 percent of non-drug-using workers.
This can mean a good supply of mulch alternatives. Grass clippings can only be used as mulch if the clippings are added to other types of mulching ingredients. The reason for this is that grass clippings do not have a free circulation of oxygen and actually can build up methane gas in larger volumes.
There are many types of mulch, from wood chips and bark to straw and even shredded paper. Mulch weight varies significantly among types. Even in loose piles, mulches such as wood chips can be quite heavy due to the density of the material. Others, such as straw, are much lighter and more airy.
