HB 1020 Colorado House · 2026 Regular Session

Colorimetric Field Drug Tests in Drug Possessions

Summary
Under current law, a person may be arrested and detained for level 1 drug misdemeanor possession.     The act requires that when a colorimetric field drug test was used to test for the presence of a controlled substance and a person is solely suspected of a level 1 drug misdemeanor for possession or solely suspected of a municipal drug possession charge, a peace officer shall not arrest the person and instead shall issue a summons.     The act also requires that when a colorimetric field drug test was used, before accepting a plea from a person charged with a drug possession for level 4 drug felony possession and lower, the trial court is required to issue an advisement with specified language, including language stating that colorimetric field drug tests have known error rates and that the defendant has the right to enter a not guilty plea and to request drug testing from an accredited forensic laboratory.(Note: This summary applies to this bill as enacted.)

MODERATE
This bill amends Colorado drug possession laws to restrict the use of colorimetric field drug tests (presumptive chemical screenings) as the sole basis for arrests or plea agreements. It mandates that peace officers issue summonses instead of making arrests, and judges must inform defendants of the test's high error rates and right to forensic testing before accepting pleas.
Scope change
The scope was expanded to explicitly prohibit arrests and plea acceptance based solely on colorimetric field drug tests for Level 1 drug misdemeanors and municipal drug possession charges.
DEFINITION

Added a new legal definition for 'colorimetric field drug test' to clarify that these are presumptive screening methods with known error rates, not definitive forensic evidence.

ENFORCEMENT

Prohibited peace officers from arresting individuals suspected of Level 1 drug misdemeanors or municipal drug possession if a colorimetric field drug test was the only evidence, requiring a summons instead.

REQUIREMENT

Required trial judges to issue a specific advisement to defendants before accepting pleas, informing them that these tests have known error rates and are inadmissible in court, and asserting their right to request forensic testing.

Modified arrest and release procedures to ensure that when a colorimetric field drug test is used for specific low-level drug charges, the individual is released with a summons rather than detained.
