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.
Many organic materials may be used as mulch. The most common are leaves, pine straw, pine bark, cypress, hardwood chips and shredded hardwood bark. Inorganic materials like woven weed barriers, gravel, crushed rock, and lava rock may also be used. Mulch can be applied at any time of the year.
