Title & Source: Longitudinal Effects of Cannabis Use on Suicidal Behaviour in Early Adulthood in Washington State, United States and Victoria, Australia. (PubMed, 2026Sep24)
Lead Authors & Identifiers: Abbey J Fitzpatrick, Jessica A Heerde, Bosco Rowland, Ebru A Batmaz, John W Toumbourou. | Primary Record: DOI: 10.1007/s11121-026-01987-z | PMID: 42782471 Content lane: Evidence Check.
1. Scientific & Clinical Background: Investigating Longitudinal Effects of Cannabis Use on Suicidal Behaviour in Early Adulthood in Washington State, United States and Victoria, Australia., researchers evaluated This study aimed to investigate the impact of cannabis use on young adult suicidal behaviour. Matched cohorts were compared across two regions: Washington State, USA (where recreational cannabis use was legalised in 2012) and Victoria, Australia (where recreational cannabis use remains illegal).
2. Detailed Findings & Primary Data: Primary observations demonstrated that Data were drawn from the International Youth Development Study (IYDS) involving 1,470 participants (55.4% female; 726 Victoria, 744 Washington State) surveyed at average ages 25 and 29 in 2014 and 2018, respectively. Victorian participants reported a reduction in cannabis use from age 25 to 29, while increased use was reported by Washington State participants across the same period. Regression analysis showed higher rates of cannabis use at 25 years and increased cannabis consumption at 29 years predicted increased suicidal behaviour.
3. Dr. Caplan’s Clinical & Practical Guidance: Despite increased risk from cannabis use, Washington State maintained lower rates of suicidal behaviour compared to Victoria, emphasising the need to understand multiple determinants of state differences in suicidal behaviour. In practical terms, these data offer a useful baseline for evaluating realistic therapeutic expectations.
4. Study Boundaries & Methodological Limits: These outcomes must be interpreted within the specific design parameters and cohort bounds of Longitudinal Effects of Cannabis Use on Suicidal Behaviour in Early Adulthood in Washington State, United States and Victoria, Australia. before generalizing broadly.
Title & Source: Cannabis use is associated with increased risk of violence: A systematic review and meta-analysis. (PubMed, 2026Sep24)
Lead Authors & Identifiers: Giulia Trotta, Victoria Rodriguez, Paolo Marino, Meklit Gurmesa, Edoardo Spinazzola, Zhikun Li, Luis Alameda, Marta Di Forti, Robin Murray, Evangelos Vassos. | Primary Record: DOI: 10.1017/S0033291726105856 | PMID: 42779465 Content lane: Clinical Evidence Update.
1. Scientific & Clinical Background: Investigating Cannabis use is associated with increased risk of violence: A systematic review and meta-analysis., researchers evaluated Cannabis use is a known risk factor for adverse mental health outcomes, including psychosis, which is frequently associated with aggression. However, the specific impact of cannabis use on the risk of violence remains unclear.
2. Detailed Findings & Primary Data: Primary observations demonstrated that Cannabis use is a known risk factor for adverse mental health outcomes, including psychosis, which is frequently associated with aggression. However, the specific impact of cannabis use on the risk of violence remains unclear. Random-effects models revealed that cannabis users are at a significantly higher risk of perpetrating violent acts.
3. Dr. Caplan’s Clinical & Practical Guidance: It also highlights the potential of cannabis use as a target for interventions to decrease violence, and underscores the need for routine assessment of cannabis use among psychiatric patients. In practical terms, these data offer a useful baseline for evaluating realistic therapeutic expectations.

Title & Source: Efficacy and Safety of Cannabinoid-Based Interventions for Low Back Pain and Migraine: A Systematic Review of Randomized Controlled Trials. (PubMed, 2026Sep22)
Lead Authors & Identifiers: Claudete da Costa-Oliveira, Magnólia de Jesus Castro, Luiza Aparecida Luna Silvério, Maria Fernanda Barros de Oliveira Brandão, Ygor Jessé Ramos, Priscila Gava Mazzola. | Primary Record: DOI: 10.1177/25785125261490003 | PMID: 42773786 Content lane: Clinical Evidence Update.
1. Scientific & Clinical Background: Investigating Efficacy and Safety of Cannabinoid-Based Interventions for Low Back Pain and Migraine: A Systematic Review of Randomized Controlled Trials., researchers evaluated Low back pain, migraine, and other headache disorders are major contributors to disability, and interest in cannabinoid-based interventions has increased despite uncertainty regarding their indication-specific therapeutic value. This systematic review evaluated the efficacy and safety of isolated cannabinoids, synthetic cannabinoids, vaporized Cannabis products, and standardized Cannabis extracts for low back pain, migraine, and medication-overuse headache.
2. Detailed Findings & Primary Data: Primary observations demonstrated that Low back pain, migraine, and other headache disorders are major contributors to disability, and interest in cannabinoid-based interventions has increased despite uncertainty regarding their indication-specific therapeutic value. Eligible studies were assessed using Risk of Bias 2, synthesized narratively according to synthesis without meta-analysis guidance, and rated for certainty using Grading of Recommendations Assessment, Development, and Evaluation (PROSPERO registration: 582772). THC-containing inhaled formulations were associated with more psychoactive adverse effects and possible functional unblinding.
3. Dr. Caplan’s Clinical & Practical Guidance: Larger independently replicated trials using analytically standardized formulations, harmonized outcomes, active-placebo strategies when THC is present, and additional studies evaluating repeated use across multiple migraine attacks and longer-term safety are needed. In practical terms, these data offer a useful baseline for evaluating realistic therapeutic expectations.
4. Study Boundaries & Methodological Limits: These outcomes must be interpreted within the specific design parameters and cohort bounds of Efficacy and Safety of Cannabinoid-Based Interventions for Low Back Pain and Migraine: A Systematic Review of Randomized Controlled Trials. before generalizing broadly.
