What the trial is, and whether it could suit you
Understanding how co-morbidities in persons with HIV (PWH) such as substance use affect risk-taking, decision-making, and other cognitive behaviors is important given implications for everyday functioning and transmission risk. The high prevalence of cannabis use in PWH, medicinally and recreationally, may indicate disease severity, impart therapeutic benefits, or adverse consequences. In fact, cannabis is recommended to those with HIV to alleviate nausea, improve appetite, relieve pain, and lift mood. To-date, the consequences of cannabis use in PWH remain unclear as do potential interactions with HIV treatments. In healthy participants, heavy cannabis use is associated with cognitive deficits e.g., risky decision-making, response disinhibition and inattention, but pro-cognitive effects in PWH may exist at mild use levels due to its anti-inflammatory and anti-excitotoxic properties.

๐ Eligibility rules (as published)
Inclusion Criteria
1. Aged 18-65
2. Possess the capacity to provide informed consent to a set of neurobehavioral, neuromedical and cognitive assessment procedures. Individuals unable to provide such consent will not be enrolled into the study.
3. Willing to confirm self-reported HIV using a rapid test: HIV status will be determined using the MedMira Rapid Test (Halifax, Nova Scotia, Canada). If the result differs from the participant's self-report a confirmatory Western Blot will be performed.
4. Willing to abstain from cannabis for at least 1 week prior to the baseline visit and during the study. Although there is no definitive method for determining abstinence over this period, abstinence will be confirmed as best as possible by using an oral fluid testing device (Draeger 5000) employed by law enforcement officers to detect recent cannabis use. An oral fluid value of \> 5ng suggests recent use, although in some cases it has been reported that individuals may show \> 5ng up to 20 hours after use. Thus, should the oral fluid sample indicate \> 5ng THC, the assessment may be canceled and rescheduled.
Exclusion Criteria

* Pregnancy
* Acute or recent or previous clinically disabling stroke or previous cerebrovascular events
