The scented article of claim 1, wherein the multilayered rod comprises a hollow core. 3. The scented article of claim 2, wherein an exposed surface of the hollow core is treated with a porosity-altering material such that a porosity of the treated exposed surface of the hollow core is different from the second porosity of the at least one interior layer. 4. The scented article of claim 1, wherein the porosity-altering material is configured to at least partially inhibit release of the at least one olfactory-active composition from the absorbent matrix material. 5. The scented article of claim 1, further comprising an engaging means for engaging the scented article with a surface, another article, or another structure. 6. The scented article of claim 5, wherein the engaging means comprises a clip, a hook, a circle, a hook and eye means, a string, prongs, a loop, adhesives, a spike, a holder, a vase, a container, and a receptacle. 7. The scented article of claim 1, wherein the multilayered rod is a spiral wound multilayered rod. 8. A scented article comprising: an absorbent matrix material wound about a central axis to form a multilayered rod having a hollow core;at least one olfactory-active composition releasably retained in the absorbent matrix material;wherein at least a portion of exposed surfaces of the rod are treated with a porosity-altering material;wherein a porosity of the treated exposed surfaces of the rod is different from a porosity of at least one non-exposed layer of the rod;wherein the porosity-altering material comprises a dye, pigment, a wax, soy wax, paraffin, bees wax, polyethylene wax, microcrystalline wax, waxes that soften or melt at a temperature greater than about 150 F, acrylates, polylactide, polyglycolide or polycaprolactone, or a polyester copolymer selected from poly(lactide/glycolide) acid (PLGA) or poly(lactid-co-epsilon-caprolact-one) (PLCL), alkyl- or alkoxyalkyl-2-cyanoacrylates, n-butyl-2-cyanoacrylate, 2-methoxybutyl-2-cyanoacrylate, crosslinked cyanoacrylate, polylactic acid, polyglycolic acid, lactic-glycolic acid copolymers, polycaprolactone, lactic acid-caprolactone copolymers, poly-3-hydroxybutyric acid, polyorthoesters, polyalkyl acrylates, copolymers of alkylacrylate and vinyl acetate, polyalkyl methacrylates, copolymers of alkyl methacrylates and butadiene; dioctyl phthalate, dimethyl sebacate, trethyl phosphate, tri(2-ethylhexy)phosphate, tri(p-cresyl)phosphate, glyceryl triacetate, glyceryl tributyrate, diethyl sebacate, dioctyl adipate, isopropyl myristate, butyl stearate, lauric acid, dibutyl phthalate, trioctyl trimellitate, dioctyl glutarate, or a starch. 9. The scented article of claim 8, wherein the porosity-altering material is configured to at least partially inhibit release of the at least one olfactory-active composition from the absorbent matrix material. 10. The scented article of claim 8, wherein the multilayered rod is a spiral wound multilayered rod. 11. A scented article comprising an absorbent matrix material wound about a central axis to form a multilayered rod;at least one olfactory-active composition releasably retained in the absorbent matrix material;a barrier material applied to at least a portion of an exterior surface of the rod;wherein the barrier material retards a release of the at least one olfactory-active composition through the exterior surface of the rod; andwherein the barrier material comprises a paper wrapping, dye, pigment, a wax, soy wax, paraffin, bees wax, polyethylene wax, microcrystalline wax, waxes that soften or melt at a temperature greater than about 150 F, acrylates, polylactide, polyglycolide or polycaprolactone, or a polyester copolymer selected from poly(lactide/glycolide) acid (PLGA) or poly(lactid-co-epsilon-caprolact-one) (PLCL), alkyl- or alkoxyalkyl-2-cyanoacrylates, n-butyl-2-cyanoacrylate, 2-methoxybutyl-2-cyanoacrylate, crosslinked cyanoacrylate, polylactic acid, polyglycolic acid, lactic-glycolic acid copolymers, polycaprolactone, lactic acid-caprolactone copolymers, poly-3-hydroxybutyric acid, polyorthoesters, polyalkyl acrylates, copolymers of alkylacrylate and vinyl acetate, polyalkyl methacrylates, copolymers of alkyl methacrylates and butadiene; dioctyl phthalate, dimethyl sebacate, trethyl phosphate, tri(2-ethylhexy)phosphate, tri(p-cresyl)phosphate, glyceryl triacetate, glyceryl tributyrate, diethyl sebacate, dioctyl adipate, isopropyl myristate, butyl stearate, lauric acid, dibutyl phthalate, trioctyl trimellitate, dioctyl glutarate, or a starch. 12.
