Sex Effects of Marijuana on Brain Structure and Function

Area of Science:

• Neuroscience
• Endocrinology
• Pharmacology

Background:

• Tetrahydrocannabinol (Δ⁹-THC), the main psychoactive component of marijuana, interacts with neurological and biological systems, including the endocrine system.
• Potential for sex-based and hormone-level-dependent differential effects of Δ⁹-THC on the human body.
• Existing research indicates Δ⁹-THC's interaction with the endocrine system suggests sex-based variations in its effects.

Approach:

• Systematic literature review examining sex-based differences in the effects of Δ⁹-THC on neural structure and function.
• Analysis of studies investigating how marijuana impacts male and female users differently.
• Synthesis of current findings on neurological and social factors contributing to these differences.

Key Points:

• Documented sex-based differences in marijuana users concerning brain structure, reward processing, attention, motor control, and withdrawal sensitivity.
• Inconsistencies in the literature highlight the need for further research into the precise mechanisms of differential effects.
• Neurological sexual dimorphism and varying social influences are likely contributors to observed sex-based variations in marijuana's effects.

Conclusions:

• Sex is a significant factor in marijuana use and the development of cannabis use disorders.
• Consideration of sex-based differences is essential for creating targeted prevention and treatment strategies.
• Further research is warranted to fully elucidate the complex interplay between sex, Δ⁹-THC, and neurobiological outcomes.
