## Abstract

The non-combustible tobacco vaping insert includes a filter having a first diameter, and a tobacco element with a first end contacting the filter, the tobacco element having a second diameter that is smaller than the first diameter of the filter. The cartridge includes a housing, where the cartridge defines an air passage within the housing, and a vaping insert is positioned in at least one first portion of the air passage. The vaping insert is non-combustible and is configured to allow vapor to pass through the vaping insert prior to exiting the cartridge. The vaping insert includes a filter having a first diameter, and a tobacco element with a first end contacting the filter, the tobacco element having a second diameter that is smaller than the first diameter of the filter.

## Claims

### Claim 1

A non-combustible tobacco vaping insert, comprising:
a filter having a first diameter; and
a tobacco element with a first end contacting the filter, the tobacco element having a second diameter that is smaller than the first diameter of the filter.

### Claim 2 (depends on 1)

The non-combustible tobacco vaping insert of claim 1, wherein the tobacco element has a uniform diameter along a longitudinal length of the tobacco element, the uniform diameter being the second diameter.

### Claim 3 (depends on 2)

The non-combustible tobacco vaping insert of claim 2, wherein the tobacco element has a cylindrical shape.

### Claim 4 (depends on 1)

The non-combustible tobacco vaping insert of claim 1, wherein the second diameter is a largest diameter of the tobacco element along a longitudinal length of the tobacco element.

### Claim 5 (depends on 4)

The non-combustible tobacco vaping insert of claim 4, wherein the tobacco element has a varying diameter.

### Claim 6 (depends on 4)

The non-combustible tobacco vaping insert of claim 4, wherein the tobacco element has a varying diameter and the first end has the second diameter.

### Claim 7 (depends on 4)

The non-combustible tobacco vaping insert of claim 4, wherein the tobacco element has a conical shape.

### Claim 8 (depends on 1)

The non-combustible tobacco vaping insert of claim 1, wherein the tobacco element is shaped as a thin sheet.

### Claim 9 (depends on 1)

The non-combustible tobacco vaping insert of claim 1, wherein the first end of the tobacco element is connected to the filter via an adhesive, the adhesive being at least one of a starch-based adhesive and a dextrin-based adhesive.

### Claim 10 (depends on 1)

The non-combustible tobacco vaping insert of claim 1, wherein the first end of the tobacco element is embedded into a surface of the filter.

### Claim 11 (depends on 1)

The non-combustible tobacco vaping insert of claim 1, wherein the tobacco element includes at least one of tobacco leaf, compressed tobacco, tobacco strands, rolled tobacco, reconstituted tobacco, filler, tobacco beads, compressed tobacco rod, shaped tobacco and tobacco powder.

### Claim 12
