Abstract

Disclosed herein are cannabis placebo compositions having an appearance, odor and flavour to match that of an active cannabis product, as well as methods for colour matching and colour neutralization of cannabis products. The compositions include a colourant to provide a colour match between the cannabis placebo composition and the active cannabis product; and a terpene, an ester, a flavonoid, or any combination thereof to provide an odor and flavour.

Claim(s)

1. A cannabis placebo composition comprising: – a base component matched to that of an active cannabis product; – a colourant to provide a colour match between the cannabis placebo composition and the active cannabis product; and – a terpene, an ester, a flavonoid, or any combination thereof to provide an odor and flavour match between the cannabis placebo composition and the active cannabis product, wherein the cannabis placebo composition is indistinguishable in appearance, odor and flavour from the active cannabis product.;
27. A method for producing a colour-matched placebo, the method comprising: providing an active sample of an active cannabis product; analyzing the active sample by spectrophotometry to obtain one or more absorbance measurements between 380 nm to 780 nm; converting the one or more absorbance measurements into absolute CIE ??? values; and adding one or more colourants to a cannabis placebo composition to match the absolute CIE ??? values of the active sample, thereby producing a colour-matched placebo.;
37. A method for neutralizing the colour of a cannabis placebo composition or an active cannabis product, the method comprising: providing a sample of a cannabis placebo composition or an active cannabis product; analyzing the sample by spectrophotometry to obtain one or more absorbance measurements between 380 nm to 780 nm; converting the one or more absorbance measurements into absolute CIE ??? values; and adding a colourant that is opposite to an undesired colour to reduce the effect of the undesired colour, thereby neutralizing the colour of the cannabis placebo composition or an active cannabis product.
