1. A medication delivery apparatus comprising: an antistatic holding chamber that has an input end and an output end spaced apart along a longitudinal axis;a patient interface component connected to said output end and comprising an interior surface defining a flow passage; anda duck-bill shaped valve disposed adjacent said output end, said duck-bill shaped valve comprising a flexible material and moveable between an open position and a closed position, wherein said duck-bill shaped valve has a central opening when in said open position, said central opening having a flow path along said longitudinal axis, so as to facilitate a flow from the antistatic holding chamber to a patient,wherein the duck-bill shaped valve is configured to block a flow of exhaled air upstream in the direction of the antistatic holding chamber, and the duck-bill shaped valve configured to permit the exhaled air to be exhausted through a sidewall of a housing. 2. The apparatus of claim 1, further comprising a backpiece separate from said holding chamber and comprising an elastomeric material having a surface resistivity that reduces a risk of resistance to medicament flow, wherein said backpiece is connected to said input end of said holding chamber. 3. The apparatus of claim 2, wherein said backpiece comprises an opening formed therethrough, said opening shaped and adapted to receive a portion of a pressurized metered dose inhaler. 4. The apparatus of claim 1, further comprising a second antistatic component separate from said holding chamber and comprising a material having a surface resistivity that reduces a risk of resistance to medicament flow, and wherein said second antistatic component is connected to said holding chamber. 5. The apparatus of claim 4, wherein said second antistatic component comprises said patient interface component connected to said output end of said holding chamber. 6. The apparatus of claim 4, wherein said second antistatic component comprises a backpiece connected to said input end of said holding chamber. 7. The apparatus of claim 6, wherein said backpiece comprises an elastomeric material. 8. The apparatus of claim 6, wherein said backpiece comprises an opening formed therethrough, said opening shaped and adapted to receive a portion of a pressurized metered dose inhaler. 9. The apparatus of claim 1, wherein said patient interface component comprises a mouthpiece. 10. The apparatus of claim 9, wherein said interior surface of said mouthpiece is not antistatic. 11. The apparatus of claim 1, wherein the duck-bill shaped valve is configured to form a wedge, the wedge having sides that are configured to flex when atmospheric pressure on one side of the duck-bill shaped valve is greater than atmospheric pressure on an opposite side of the duck-bill shaped valve. 12. The apparatus of claim 1, further comprising a receptacle comprising a flexible material positioned at the input end of said antistatic chamber and configured to accept a source of medication. 13. The apparatus of claim 12, wherein said receptacle is configured to be removed from said antistatic chamber for replacing the receptacle. 14. A medication delivery apparatus comprising: an antistatic holding chamber that has an input end and an output end spaced apart along a longitudinal axis;a patient interface component connected to said output end and comprising an interior surface defining a flow passage;a duck-bill shaped valve disposed adjacent said output end, said duck-bill shaped valve comprising a flexible material and moveable between an open position and a closed position, wherein said duck-bill shaped valve has a central opening when in said open position, said central opening having a flow path along said longitudinal axis, so as to facilitate a flow from said antistatic holding chamber to a patient, wherein said duck-bill shaped valve is configured to block a flow of exhaled air upstream in the direction of said antistatic holding chamber; anda receptacle comprising a flexible material positioned at the input end of said antistatic holding chamber and configured to accept a source of medication. 15. The apparatus of claim 14, further comprising an adaptor positioned between said patient interface and said antistatic holding chamber, said adaptor comprising a housing configured with a vent. 16. The apparatus of claim 15, wherein said duck-bill shaped valve is configured to permit the exhaled air to be exhausted through said vent. 17. The apparatus of claim 14, further comprising a backpiece separate from said holding chamber and comprising an elastomeric material having a surface resistivity that reduces a risk of resistance to medicament flow, wherein said backpiece is connected to said input end of said antistatic holding chamber, wherein said backpiece comprises an opening formed therethrough, said opening shaped and adapted to receive a portion of a pressurized metered dose inhaler. 18. The apparatus of claim 14, further comprising a second antistatic component separate from said antistatic holding chamber and comprising a material having a surface resistivity that reduces a risk of resistance to medicament flow, and wherein said second antistatic component is connected to said antistatic holding chamber. 19. The apparatus of claim 14, wherein said receptacle is configured to be removed from said antistatic holding chamber for replacing the receptacle. 20. A medication delivery apparatus comprising: an antistatic holding chamber that has an input end and an output end spaced apart along a longitudinal axis;a patient interface component connected to said output end and comprising an interior surface defining a flow passage;a duck-bill shaped valve disposed adjacent said output end, said duck-bill shaped valve comprising a flexible material and moveable between an open position and a closed position, wherein said duck-bill shaped valve has a central opening when in said open position, said central opening having a flow path along said longitudinal axis, so as to facilitate a flow from said antistatic holding chamber to a patient, wherein said duck-bill shaped valve is configured to block a flow of exhaled air upstream in the direction of said antistatic holding chamber; andan adaptor positioned between said patient interface and said antistatic chamber, said adaptor comprising a housing configured with a vent. 21. The apparatus of claim 20, wherein said duck-bill shaped valve is configured to permit the exhaled air to be exhausted through said vent. 22. The apparatus of claim 20, further comprising a receptacle comprising a flexible material positioned at the input end of said antistatic holding chamber and configured to accept a source of medication. 23. The apparatus of claim 22, wherein said receptacle is configured to be removed from said antistatic holding chamber for replacing the receptacle.
