The subject invention provides colorimetric test strips and fast screening field test kits for differentiating between cannabinoids in cannabis samples, preferably, for differentiating marijuana from other cannabis plants, e.g., hemp. The fast screening field test kit can also be used for confirming the presence of marijuana in a complex cannabis sample. The colorimetric test strips use a solid substrate (e.g., capillary microextraction of volatiles (CMV) device) for the colorimetric reaction. The non-polar nature of the CMV sorbent does not allow the reaction of FBBB and THC to spread, producing an intense red color in the presence of a plant with high concentration of THC (e.g., marijuana) or an orange color in the presence of a plant with a high concentration of CBD (e.g., hemp).

Disclosed herein, inter alia, are methods of treating renal disease (e.g., chronic kidney disease or end stage renal disease).

A method for producing powderized cannabis oil, powderized cannabis oil, and edible products and beverages comprising the powderized cannabis oil. Powderized cannabis oil contains cannabis oil and maltodextrin in a ratio of at least three grams of maltodextrin for every one-eighth of a gram of cannabis oil. Edible products and beverages incorporating the powderized cannabis oil are human-consumable products that contain an emulsified, tasteless, and odorless dose of cannabis oil providing CBD, THC and/or THCA.

Systems, techniques and compositions can detect and measure a target substance, such as THC, in a constituent sample from exhaled human breath.

The present invention relates to a compound of formula (I)

##STR00001##

wherein R.sup.1, R.sup.2, and R.sup.3 are defined as in the description and in the claims. The compound of formula (I) can be used as a radiolabeled ligand.

The various technologies presented herein relate to identifying whether an individual has taken, and/or is under the influence of, a restricted drug. A density separation technique is utilized, wherein a sample (e.g., blood, saliva, urine, etc.) which may include an analyte is exposed to a first plurality of beads having an analyte attached thereto, a second plurality of beads having a metabolite-specific antibody attached thereto, and a plurality of fluorophore-labelled analyte-specific antibodies. After incubation, any analyte in the sample (e.g., delta-9-THC) is bound to the fluorophore-labelled analyte-specific antibodies, any free fluorophore-labelled analyte-specific antibodies are attached to the analyte of the first beads, and any metabolite in the sample is bound to the second antibody. By applying centrifugal separation, the first beads move to a region which undergoes irradiation. If no fluorescence occurs, the sample includes the analyte; if fluorescence occurs, the sample does not include the analyte.

A method for producing powderized cannabis oil, and the resulting powderized cannabis oil, in which concentrated cannabis oil is mixed with and absorbed by a modified starch powder, preferably maltodextrin, in a ratio of at least three grams of starch powder for every one-eighth of a gram of cannabis oil is disclosed. Further disclosed are beverages, baked goods and single-serve beverage brewing cartridges utilizing or incorporating the powderized cannabis oil to create human-consumable products that contain an emulsified, tasteless, and odorless dose of cannabis oil.
