Abstract

Methods and devices for sampling, processing and identifying use of a substance or substances of abuse are provided. Systems and kits for sampling, processing and identifying acute use of a substance of abuse is also provided.

Claims (31)

1. An apparatus comprising:

one or more sampling modules to process multiple samples for one or more analysis substances;

a processing unit operatively coupled to the one or more sampling modules, the processing unit being configured to:

over a first time period, perform a first sample acquisition for a first sample, and execute a first routine to determine whether a predetermined amount of a first analysis substance is present in the first sample; and

over a second time period that is concurrent to the first time period, perform a second sample acquisition for a second sample that is different from the first sample, and execute a second routine to determine whether a predetermined amount of a second analysis substance is present in the second sample; and

generate one or more signals that are based on whether the predetermined amount of the first analysis substance or the second analysis substance is present in the first and second sample.

2. The apparatus of claim 1 , wherein the first analysis substance is indicative of or includes a first target substance that includes THC, and the second analysis substance is indicative of or includes a second target substance that is different from the first target substance.

3. The apparatus of claim 2 , wherein the second target substance is alcohol.

4. The apparatus of claim 2 , wherein the second target substance is one of codeine, cocaine, morphine, or methamphetamine.

5. The apparatus of claim 1 , wherein the processing unit determines at least one of (i) an amount of the first analysis substance that is present in the first analysis substance, or (ii) an amount of the second analysis substance that is present in the second analysis substance.

6. The apparatus of claim 1 , wherein the first sample is of a first type, and the second sample is of a second type.

7. The apparatus of claim 1 , further comprising:

an output component operatively coupled to the processing unit, the output component generating an output that is based on the one or more signals.

8. The apparatus of claim 1 , wherein the processing unit is configured to determine at least one of (i) an amount of the first analysis substance based at least in on a half-life of the first analysis substance, or (ii) an amount of the second analysis substance based at least in on a half-life of the second analysis substance.

9. The apparatus of claim 1 , wherein the processing unit is configured to determine whether the predetermined amount of the first analysis substance is present in the first sample by:

executing the first routine at multiple times to determine a first gradient; and

determining an amount of the first analysis substance based on the first gradient.

10. The apparatus of claim 9 , wherein the processing unit is configured to determine whether the predetermined amount of the second analysis substance is present in the second sample by:

executing the second routine at multiple times to determine a second gradient; and

determining an amount of the second analysis substance based on the second gradient.

11. The apparatus of claim 1 , wherein in response to executing the first routine to determine that the predetermined amount of the first analysis substance is not present, repeating executing the first routine to determine whether the predetermined amount of the first analysis substance is present.

12. The apparatus of claim 1 , wherein in response to executing the second routine to determine that the predetermined amount of the second analysis substance is not present, repeating executing the second routine to determine whether the predetermined amount of the second analysis substance is present.

13. A method comprising:

over a first time period, performing a first sample acquisition for a first sample, executing a first set of steps to determine whether a predetermined amount of a first analysis substance is present in the first sample;

over a second time period that is concurrent to the first time period, performing a second sample acquisition for a second sample that is different from the first sample, and executing a second set of steps to determine whether a predetermined amount of a second analysis substance is present in the second sample; and

generating an output that is based on (i) whether the predetermined amount of the first analysis substance is present in the first sample, and (ii) whether the predetermined amount of the second analysis substance is present in the second sample.

14. The method of claim 13 , wherein the first analysis substance is indicative of or includes a first target substance that includes THC, and the second analysis substance is indicative of or includes a second target substance of that is difference from the first target substance.

15. The method of claim 14 , wherein the second target substance is alcohol.

16. The method of claim 14 , wherein the second target substance is one of codeine, cocaine, morphine, or methamphetamine.

17. The method of claim 13 , wherein in response to performing the first set of steps to determine that the predetermined amount of the first analysis substance is not present, repeating performing the first set of steps to determine whether the predetermined amount of the first analysis substance is present.

18. The method of claim 13 , wherein in response to performing the second set of steps to determine that the predetermined amount of the second analysis substance is not present, repeating performing the second set of steps to determine whether the predetermined amount of the second analysis substance is present.
