More than 2,700 drivers were arrested for drug-related offences in January as authorities expanded roadside inspections and medical testing. Separate road safety checks in Keighley recorded 17 offences, including one drug-driving arrest.
A longitudinal study of 460,000 teenagers found adolescent cannabis use was linked to higher risks of later bipolar, psychotic, anxiety and depression diagnoses. Separate research and expert guidance say THC effects, especially long term, still need more study.
A large Kaiser Permanente study of 463,396 adolescents found those using cannabis were twice as likely to develop psychotic or bipolar disorders, with elevated risks for depression and anxiety. The research suggests adolescence is a vulnerable period for cannabis-related mental health harms, though causality remains complex.
A study of over 600,000 patients reveals GLP-1 drugs may reduce addiction across multiple substances, with 50% fewer substance-related deaths and significant reductions in overdoses and hospitalizations. The drugs work by dampening dopamine signaling in brain reward centers. Researchers are exploring broader applications for these medications beyond diabetes and obesity treatment.
A months-long drug investigation in North Carolina led to four arrests and over 70 felony charges, with seizures including firearms and 120 grams of cocaine and methamphetamine. Separately, a traffic stop revealed cocaine, marijuana, and a firearm, highlighting ongoing regional drug activity. Law enforcement officials note challenges from differing state marijuana laws and increasing drug-related incidents.
A longitudinal study of 460,000 teenagers found that adolescent cannabis use increases the risk of developing bipolar and psychotic disorders by twofold, as well as raising risks for depression and anxiety.
