“…It is possible that using other substances in conjunction with cannabis heightens the psychoactive effects of cannabis, resulting in greater endorsement of odd/unusual thinking or perceptual abnormalities. For example, the common practice of including tobacco in cannabis preparations substantially increases the amount of THC inhaled per gram of cannabis [37], which may increase its potency and resultant psychosis risk [38]. Further, previous work [21] found that users of both cannabis and other illicit drugs reported more positive symptoms than non-cannabis users and than users of both cannabis and legal drugs.…”

Purpose To examine how cannabis use and polysubstance use among cannabis users relate to psychosis spectrum (PS) symptoms in a large community-based sample of US youth. Methods 4,171 youth (age 14–21; mean=16.90, SD=1.85; 55% female) from the Philadelphia Neurodevelopmental Cohort (PNC) completed assessments of substance use, PS symptoms, and confounding variables (e.g., demographics, comorbid psychopathology, trauma exposure). Results After adjusting for confounds, cannabis use by itself was not associated with increased odds of being classified as “psychosis spectrum.” However, cannabis use in combination with tobacco or other substance use was associated with increased odds of PS classification (adjusted odds ratios [ORs] = 1.37 to 1.76). Follow-up symptom-level analyses revealed that cannabis use in combination with other substances was associated with subclinical positive symptoms (ORs=1.95 and 2.24) and frequent cannabis use was associated with subclinical negative/disorganized symptoms (OR=2.14). However, these symptom-level findings were reduced to trends after correction for multiple comparisons. Neither cannabis use nor polysubstance use was associated with threshold delusions or hallucinations. Conclusions After adjusting for important confounds, there was minimal evidence for associations between cannabis use by itself and PS symptoms. More compelling evidence emerged for associations between polysubstance use among cannabis users and PS symptoms. This study highlights the importance of considering polysubstance use and confounds when examining associations between cannabis use and PS symptoms. Further longitudinal research is necessary to determine whether these findings represent causal associations or shared genetic and/or environmental vulnerability for substance use and PS symptoms.

“…Reasons for this preference include the fact that the combustion of both cannabis and tobacco together increases the vaporization effi ciency of THC per gram of cannabis and may contribute to enhanced psychogenic eff ects compared with smoking cannabis alone. 20 Th is suggests that concurrent use of tobacco and cannabis could compound eff ects on airways pathology, and indeed, one study reported additive eff ects. 15 Th erefore, accurate histories regarding both cannabis and tobacco use along with additional information regarding methods of use are important clinically and in scientifi c investigations.…”
