A double-blind, placebo-controlled, within-subjects crossover design will be used to examine the dose-effects of THC (0, 5mg, 30mg) on oculomotor performance tasks and a sustained attention task in frequent and infrequent cannabis users. Results from the study will advance the investigators' understanding of the effect of THC and cannabis use frequency on oculomotor function and sustained attention, and will directly inform the validity of the investigators' oculomotor platform for identifying acute THC- induced impairment in frequent and infrequent users.",[27,28,29],"Cannabis Use","Impaired Driving","Cognitive Impairment",[31,32,33],"cannabis","THC","impairment","NOT_YET_RECRUITING","2026-05-26",{"date":37,"type":38},"2026-05-27","ACTUAL",{"date":40,"type":21},"2026-08-01",{"date":42,"type":21},"2027-07-01",{"name":44,"class":45},"Johns Hopkins University","OTHER",1,{"id":48,"slug":49,"hasResults":11,"nctId":50,"briefTitle":51,"officialTitle":51,"acronym":52,"eligibilityCriteria":53,"healthyVolunteers":11,"sex":16,"minAge":17,"maxAge":54,"enrollmentInfo":55,"targetDuration":4,"studyType":22,"phases":57,"briefSummary":59,"conditions":60,"keywords":4,"overallStatus":34,"whyStopped":4,"lastUpdateSubmitDate":61,"lastUpdatePostDateStruct":62,"startDateStruct":64,"completionDateStruct":66,"leadSponsor":68,"locationsCount":4},"100621305","assessing-the-effectiveness-of-screening-brief-intervention-and-referral-to-treatment-sbirt-with-personalized-feedback-intervention-to-reduce-polysubstance-impaired-driving-in-young-adults-aged-18-30-100621305","NCT07368894","Assessing the Effectiveness of Screening, Brief Intervention, and Referral to Treatment (SBIRT) With Personalized Feedback Intervention to Reduce Polysubstance Impaired Driving in Young Adults Aged 18-30","ADAPT","Inclusion Criteria:\n\n* Aged 18-30 at enrollment\n* Received Screening, Brief Intervention, and Referral to Treatment (SBIRT) in the past 3 month\n* Through SBIRT screened at moderate or moderate-to-high risk based on substance use OR reported any impaired driving the past 6 months\n* Lives in Washington State\n* Received a study information card from an SBIRT provider\n* Consents to having Zip Code use for analyses\n* Consents to randomization to receive brief online personalized intervention or waitlist control\n\nExclusion Criteria:\n\n* Not meeting eligibility criteria\n* Inability to confirm participant's identity, residency, or date received SBIRT.","30 Years",{"count":56,"type":21},600,[58],"NA","The current study is assessing the effects of receiving Screening, Brief Intervention and Referral to Treatment alone versus also receiving a brief online personalized intervention on impaired driving behaviors among Washington State young adults aged 18-30.",[28],"2026-01-20",{"date":63,"type":38},"2026-01-27",{"date":65,"type":21},"2026-01-31",{"date":67,"type":21},"2028-09",{"name":69,"class":45},"University of Washington"]
