Understanding how people use high-potency cannabis concentrates

THC titration of high-potency cannabis concentrates: A randomized crossover trial

NIH-funded research Centre for Addiction and Mental Health · NIH-11131146

This project looks at how regular cannabis users adjust their dose when using strong cannabis concentrates and what effects these products have on their body and mind.

What this research studies

We want to learn if people naturally use less of a cannabis concentrate when it's very strong, or if they still end up taking in more THC. We will ask regular cannabis users to try different strengths of cannabis concentrates (30%, 60%, and 90% THC) in a controlled setting. We'll then observe how they adjust their use and measure the effects on their feelings, thinking, body functions, and how much THC is in their system. This helps us understand the real-world impact of these products.

Who could benefit from this research

Good fit: Ideal participants are regular cannabis consumers, specifically 18 females and 18 males, who are willing to participate in a controlled study.

Not a fit: Patients who do not use cannabis or are not regular consumers of high-potency concentrates would not directly benefit from participating in this specific study.

Why it matters

Potential benefit: This work could help inform public health guidelines and regulations for high-potency cannabis products, potentially reducing risks like cannabis use disorder or impaired cognition.

How similar studies have performed: Limited evidence suggests that while consumers may use less cannabis as potency rises, they still consume greater amounts of THC, making this a crucial area for further investigation.
