Driving a motor vehicle after the use of narcotic substances constitutes a criminal offense under Article 343b, paragraph 3 of the Bulgarian Criminal Code. Bulgarian criminal law adopts a \u201czero tolerance\u201d model, under which no specific concentration threshold is required, nor is it necessary to prove an actual degree of impairment.<\/p>\n
Unlike alcohol-related offenses, where statutory concentration limits exist, any detected amount of a narcotic substance is sufficient to trigger criminal liability. It is not necessary to establish actual incapacity to drive or the occurrence of danger; the mere presence of a substance included in the legally defined list is sufficient.<\/p>\n
This legislative approach is justified by the absence of a universally recognized and objective medical method capable of determining the degree of impairment and the functional fitness of the driver at the relevant time.<\/p>\n
For criminal law purposes, narcotic substances are those included in the lists contained in the Final Provisions to Council of Ministers Decree No. 9 of 27 January 2022 amending the Ordinance on the Procedure for Classifying Plants and Substances as Narcotic, adopted by Decree No. 293 of 2011.<\/p>\n
Therefore, criminal liability depends not on the general medical definition of a narcotic, but on its explicit inclusion in the statutory lists. If a substance is not listed, its presence in the driver\u2019s body cannot form the basis for liability under Article 343b(3) of the Criminal Code.<\/p>\n
The substances are divided into three groups:<\/p>\n
\u2022 High-risk substances prohibited for medical use \u2013 including amphetamines, cannabis, hashish, LSD, methamphetamines, coca leaves, and others.
\u2022 High-risk substances permitted for medical use \u2013 including codeine, morphine, hydrocodone, and benzodiazepines (e.g., diazepam).
\u2022 Risk substances permitted for medical use \u2013 such as alprazolam.<\/p>\n
It is important to note that some of these substances are components of widely prescribed medications. Consequently, a driver may test positive following lawful medical treatment without intending narcotic use in the common sense.<\/p>\n
Criminal liability requires actual driving of a motor vehicle on a public road. Being inside a parked vehicle with the engine off does not constitute driving.<\/p>\n
Before conducting a test, police officers prepare a protocol describing observed behavioral indicators suggesting drug use.<\/p>\n
Testing is performed using approved single-use kits and includes:<\/p>\n
\u2022 Collection of an oral fluid sample;
\u2022 Placement of the sample in a container;
\u2022 Immersion of a test strip marked with identification data;
\u2022 Visual reading of the result via a control indicator.<\/p>\n
A control line confirms test validity. The absence of a line opposite a specific substance indicates a positive result. The sample must then be sealed.<\/p>\n
The driver is legally obliged to cooperate. In case of refusal, dispute, invalid sample, or impossibility to provide one, a referral for chemical-toxicological testing is issued.<\/p>\n
The procedure includes:<\/p>\n
\u2022 Two blood samples (one control sample);
\u2022 One urine sample;
\u2022 A medical protocol describing the driver\u2019s condition;
\u2022 Storage of samples for up to one year.<\/p>\n
The results are documented in an expert report and forwarded to the investigative authorities. The individual may request a repeat analysis at their own expense.<\/p>\n
Failure to comply with statutory testing methodology may render the expert report inadmissible as evidence. For example, conducting only one analysis without a second confirmatory analysis may constitute a procedural violation.<\/p>\n
Such violations may lead to exclusion of evidence and possible acquittal.<\/p>\n
Driving after the use of narcotic substances constitutes a criminal offense whenever any concentration of a listed substance is detected. The law does not require proof of actual impairment.<\/p>\n
Given the strict liability regime and complex evidentiary standards, strict procedural compliance is crucial for the outcome of the case.<\/p>\n
