Abstract

A system for filtering vaporized medicinal compounds includes a vaporizer configured to release one or more volatilized medicinal compounds in gaseous form, together with solid or semi-solid particulate byproducts, and one or more removable filters for efficiently removing at least a portion of the particulate byproducts while allowing passage of medicinally active volatilized compounds. The vaporizer includes a mouthpiece through which one or more volatilized medicinal compounds may be drawn. The filter is made of a chemically inert material (e.g., polypropylene or other polyolefin) and may be configured to detachably interface with an exposed surface of a vaporizer mouthpiece. The filter acts to remove solid or semi-solid particulate matter passing through the mouthpiece with minimal chemical and/or physical interference with volatilized medicinal compounds, which pass through the filter. The removable filter can also prevent cross-contamination by multiple users of the vaporizer.

Claim(s)

1. A method of filtering solid and/or semi-solid particulate matter from a medicinal vapor, comprising: providing a filter having a filter structure that is initially flat and flexible; providing a vaporizer that is a smoking device suitable for burning a plant or plant-derived material, wherein burning the plant or plant-derived material produces a medicinal vapor comprising one or more volatilized medicinal compounds and solid and/or semi-solid particulate matter selected from soot, embers, ash, and/or tar; removably applying the filter over a distal opening and mouth-contacting surface of a mouthpiece of the vaporizer so that the filter covers the distal opening and is wrapped around the mouth-contacting surface of the mouthpiece; burning the plant or plant-derived material and forming a medicinal vapor in the vaporizer, the medicinal vapor comprising one or more volatilized medicinal compounds and solid and/or semi-solid particulate matter selected from soot, embers, ash, and/or tar; passing the medicinal vapor through the mouthpiece and through the filter; and the filter removing at least a portion of the solid and/or semi-solid particulate matter from the medicinal vapor while permitting a majority of the one or more volatilized medicinal compounds in the medicinal vapor to pass through the filter.;
17. A method of oral administration of cannabinoid vapor to a group of users sharing a single vaporizer while minimizing or preventing cross-contamination of the vaporizer, comprising: providing a plurality of filters, each having a filter structure that is initially flat and flexible; providing a vaporizer that is a smoking device suitable for burning a plant or plant-derived material, wherein burning the plant or plant-derived material produces a medicinal vapor comprising one or more volatilized medicinal compounds and solid and/or semi-solid particulate matter selected from soot, embers, ash, and/or tar; removably applying a first filter over a distal opening and mouth-contacting surface of a mouthpiece of the vaporizer so that the first filter covers the distal opening and is wrapped around the mouth-contacting surface of the mouthpiece; burning the plant or plant-derived material and forming a medicinal vapor in the vaporizer, the medicinal vapor comprising one or more volatilized cannabinoid compounds and solid or semi-solid particulate matter selected from soot, embers, ash, and/or tar; a first user drawing the medicinal vapor through the mouthpiece and the first filter; removing the first filter from the mouthpiece of the vaporizer; removably applying a second filter over the distal opening and mouth-contacting surface of the mouthpiece so that the second filter covers the distal opening and is wrapped around the mouth-contacting surface of the mouthpiece; and a second user drawing the medicinal vapor through the mouthpiece and the second filter, the first and second filters each filtering at least a portion of the solid or semi-solid particulate matter from the medicinal vapor, permitting a majority of the one or more volatilized cannabinoid compounds to pass through the filters, and minimizing or preventing cross-contamination of the vaporizer by the first and second users.
